Cornish Pasties

Now we’ve made some pastry we are going to use it to make Cornish pasties. These are a great traveling food. They are a complete portable meal and originated as a convenient way for farm workers and miners to carry a wholesome meal for the day. The pastry edge is used to hold the pie.

You can read about their origin here at the Cornish pasty association.

A pasty is basically a kind of pie where the ingredients are wrapped up in an easy to hold way. There are lots of possible ingredients. Today I will make meat pasties and cheese and onion pasties.

The pastry from before is enough to make 4 large and 4 small pasties. you can prep while the pastry dough is cooling in the fridge.

First start browning the meat. Here I have 1kg of minced beef. You can also use cubes of meat and chopped potato.

While that is cooking, chop the vegetables. Here are 4 onions with the one powered kitchen tool I use, the fantastic Bosch Ergomix 750 chopper.

I also finely shred potatoes and carrots to add to the mix. Pretty much anything can go in.

And some cheese blocks.

I added half the onion and shredded potatoes to the meat with some seasoning.

And separately sauteed more onion and potatoes for the cheese and onion pasties. Then I added some crushed tomatoes to the meat. You can also add flavourings like curry powder and chili.

 

Now lets use the pastry. It needs to have been out of the fridge for half an hour so it is pliable. We’ll need an egg to make it stick when we seal the pasty.

Roll it to less than 1/4 inch.. you will need some flour to stop it sticking to the roller and surface. Pictured is one quarter of the doubled pastry recipe.

Don’t worry if it tears… worst case you can reform it into a ball and start again. Next use a guide to cut it into a circle.

Then add the filling. You can add flavourings before you fill. I like to add Thai Chili, Indian Curry, or Brown Sauce.

Brush the edge with the egg… and fold over.

Then crimp it shut with your fingers. You can make a nice fancy crimped edge if you get good at this. I tend to overload the pasty with too much filling … try not to do that as it makes the pie difficult to seal.

I take the remaining pastry, form it back into a ball and make another  one.

Here is the Potato and Onion mix with some cheese added.

Poke a hole in the top to let steam escape.. here I made a different shape with the crimp in the top as well. Ready to go on an oven tray on some parchment (baking) paper.

Put in the oven at 220C for about 10 minutes and then reduce the temperature to 180C for the next 20 minutes. And you get delicious pasties.

They freeze well. The large ones make a good meal for 2 at lunch.

Pastry for pies

I decided it was a good time to stock up on some food for our upcoming ski trip. First step was to make pastry. There are a lot of recipes around so I blended a few of them.

You need:

2 1/2 cups of Flour, 250g Unsalted Butter, 1 egg, 1 tsp Salt, 1 tsp of lemon juice, 1 tsp Sugar, 2tbsp water, and if you have it 1 tsp baking powder.  I doubled the entire recipe as I was stocking the freezer and feeding 4 so I used 5 cups of flour and 500g butter etc.

First step is to freeze the butter. Make sure it was the unsalted kind. This helps a lot with cutting it up small enough to blend in the flour.

You want to Cut it into small cubes. Be very careful cutting up the frozen butter as you can get hurt if you slip. Because it is frozen you have time to  sowork the butter.

 

I find that if you use only chilled butter, it becomes very soft before you are done whereas the frozen works well.

Next mix the flour, salt, sugar and baking powder (don’t worry if you don’t have the later as we will be making pies so the rising is not critical).

pastry5a.JPG

Now mix in the butter and cut it into the flour until it is well blended and the lumps of butter are gone.

pastry5

I use 2 spatulas to start… you can see here the lumps are coated and are blending in. You may find the lumps are too frozen still… just be patient as with the constant motion of the spatulas in a criss-cross motion the lumps will break up.

pastry6.JPG

Then towards the end I use my hands… the warmth from my hands helps the final blending in of the butter into a nice crumbly mix. You can feel the dough forming at this stage.

pastry7.JPG

Now mix all the liquid ingredients (egg, water, lemon juice) in a mixing jug and add it to the dough. It will start to bind the mix together and form into a real dough very rapidly. You may find you need to use some extra water for the rest. I find that recipes are never exact as  there is some variability due to humidity etc. You just need to get a feel for the process and feel of the dough when it is ready.  Remember that these pictures show a double recipe. I find that it is pretty forgiving.. no need to worry about being precise.

Then form the dough into patties (lumps) that you will eventually roll to make the pastry. Wrap the dough in plastic film and put it in the fridge for at least 1 hour before using. My double recipe made 4 manageable lumps of dough.

When you use it you will need to remove it from the fridge for 30 minutes before rolling so that it becomes pliable (as the butter warms) and does not crack when rolled.

Oscilloscope

Once you are building electronics projects, the ability to take a look at what is going on in the real world is invaluable for troubleshooting. For this you really need an oscilloscope which are usually quite expensive. I found this kit that gives a low cost way of entering the world of electronics instrumentation.

oscilloscopekit

I bought the version with the surface mount chips presoldered as they are tiny and I was careful to sort the components before starting.

oscilloscopechip

I used my component tester to make sure that I was using the right components. Here it is working connected to the test signal.

oscilloscope1 (3)

You can power it from a small 9V battery making it very portable. While it only works up to 200kHz and the screen in tiny at 2.4 inches, that is plenty good enough for most projects and you can’t beat being able to see what is happening when you are building a project or writing some software that interacts with the real world.

Roast Chickpeas

If you are looking for a healthy alternative to crisps (chips) roasted chickpeas make a nice snack.

Drain some cans of chickpeas and pat them dry (pictured are 2 cans worth). Put them on an oven tray on some parchment (baking) paper) and add 1 table spoonful of oil and flavour to taste. Here you can see from left to right:

  • cayenne pepper
  • garlic
  • curry powder

roastchickpeas1

Heat at 450F (230C) for about 40 minutes… take care near the end of the cooking as they finish roasting quite quickly… check at 35 minutes and keep an eye on them until they are done.

roastchickpeas2

Yummy!

 

 

 

 

Component Tester

When doing electronic projects, its critical to put in the right components. I found this fantastic component tester that solves that problem economically.

componenttester1 (2)

It can test Transistors, Diodes, LEDs, resistors, capacitors and Inductors.

Here are a few more modes.

 

The unit automatically detects the type of device under test. See how for the LED the forward voltage has been tested.

I purchased it from here: Banggood Component Tester

You can get kits and a few variations on the basic theme. I purchased a ready made one as the point was to be able to test components for building other kits. So far its been $22 well spent as I was able to avoid making mistakes when reading tiny 5 band resistor colour codes  like these that I had to use an eye loupe to read. In this case the red and brown were so close in colour I really needed the tester to be sure. Its much easier than a multi-meter. It has 3 ports for transistors. The only slight flaw i can see is sometime with an open port it thinks there might be a very large resistor present, but it still measures the device under test correctly. Also it does not measure under 30pF capacitors.

resistors1

I did some research and found these original sources that contain the schematics and code and theory of operation.

More Dehydration

We’ve really enjoyed the dehydrated food we have made, but the oven is not that energy efficient and you have to keep an eye on it…. we don’t like leaving the oven running overnight and the temperature is a bit tricky to keep constant at the low levels needed for dehydration. So we’ve taken the step of buying a real dehydrator.

We looked at a lot of reviews with the following criteria; works well at the primary job of dehydrating; can dehydrator a large quantity; not too much counter space taken up; inbuilt fan, temperature control and timer; a reasonable price; and we came up with the following unit which so far has really impressed us. Here it is at the manufacturer’s site.  Klarstein Dehydrator

dehydrator1

 

The unit takes 6 trays in a stack. You can adjust them for 2 thicknesses of food easily just by rotating them, and it comes with a fine mesh insert for small foods like berries. It has a timer and temperature control. The heater is at the bottom and there is a fan for circulating the air.

Here it is in action with some fruit. As you can see we are using 3 of the 6 possible trays which is another advantage of this design. Its also rectangular which is efficient on the counter space and for storage, whereas there were several round ones we looked at that were less easy to store.

So far it seems great. You can adjust the order of the trays easy to compensate for different speeds of drying and the timer and temperature control mean we can set it running overnight.

 

Replacing a Zipper pull

I’m a fan of trying to repair stuff as it can really prolong the value. Too often in this day and age people throw out perfectly good stuff that can be fixed with a little bit of patience. The zipper on one of my favorite fleeces failed and I could not do it up or remove it… a repair was pretty simple and a fraction of the price of  taking it in to be fixed. This fleece has a plastic zipper so I could not remove teeth to get the slider off (with metal teeth you can replace the slider by removing a tooth and then re-attaching it). As you can see the pull had worn through and it kept coming off the slider.

zipper1

First I removed the broken part. Then I made a replacement from 1.5mm copper wire (16-14AWG). I formed this into a rectangular shape with an overlap using needle nose pliers.

zipper2

Then put this through the hole in the slider and closed the loop. (oops forgot to take a picture before I soldered it). I own a soldering iron so I joined the wire with solder (being careful to keep the heat from the zipper and fleece by using the pliers as a heatsink), but epoxy glue will work just as well. File the ends to keep them smooth so they don’t snag.

zipper3

and now it works just like new.

zipper4

You can do the same with a paper clip (although copper will wear well as it is ductile and was easy to join)

Dehydrating Fruit

As we like backpacking, we have started experimenting with dehydrating food to keep weight down. While you can buy special dehydrated meals, they are expensive and we’ve found its pretty easy to do it yourself.

Here is our process for dehydrating fruit. You can do this with canned or fresh fruit. If the fruit is canned you need to drain the juices.

fruitdehydration1

Here we have a mix of fresh apples, and canned peaches, pears and pineapples (We’ll report on the mandarins pictured in a future post). You need airflow to dehydrate the fruit so we have put them on an oven rack above a tray lined with some parchment (baking) paper to catch any drips. Note: do not use wax paper… it will catch fire.

fruitdehydration2

We can dehydrate them in the oven (electric). To do that we put it on a low temperature and use a oven thermometer to monitor the temperature. You want a max of about 70C as above that temperature the fruit cooks. We prop the door open a bit using the handle of a wooden spoon to allow for air to circulate.

fruitdehydration3

After 6 to 12 hours depending on the moisture levels you have delicious fruit strips.

fruitdehydration4

Here you can see that I got the temperature a little bit high as the pineapple has browned a bit. You don’t need any sugar or oils to do this. You end up with incredibly concentrated fruit strips. Remember to drink water with them when you eat them as they have very little moisture inside. If you do a good job the fruit will last for months if you seal them (they reabsorb moisture from the air) … although they are so tasty we eat them pretty quick. The fruit is fantastic in home made granola as it really adds a bit of zing to the flavour.

Zombie Candles

If you are like us and you live in a northern clime, you may like the brightness of candles. We typically burn them in our fireplace as it a great safe place for it.

candlesburning

And of course you end up with lots of left over wax.

Well its pretty simple to generate an everlasting supply. We call them Zombie candles as we can take some larger Ikea candles and get at least 3 or 4 lives from each one. We light them in a handy ceramic tray that we also purchased at Ikea and when they burn down we recover the wax.

candles1

To melt them we use a steel pot in a pan of water that we heat on the electric stove… that way you don’t run a risk of fire. Keep the pan below boiling temperature … paraffin wax melting point is less than 70C.

candles1acandles2candles1b

For moulds, you can purchase fancy ones, but we just use the typical cardboard milk and juice cartons that have a waxy layer inside so they release easily.

candles3

For the wicks you need cotton twine.. you can buy it made for wicks with a loose weave very cheaply … I’ll stress that you need to use cotton… don’t use any type of plastic string as it will burn. We’ve tried a few methods for keeping the wicks straight… you can tie it to a washer (that you will recover when you remelt the next time)… or pre-dip it in the hot wax you are melting. Hang the wick from a wood skewer.

candles3a

Once the wax is melted, the old wicks and any washers tend to sink to the bottom… so you can now take the pot with oven gloves and pour the wax carefully into the moulds.

candles4

Let the candles cools for 24 hours and you have a reborn candle.

candles6

If you want to inject more colour, you can use cheap kids wax crayons added to the mix. We think this is a great way to enjoy candles and be economical about it without throwing away the usual wax meltings.

As always.. be safe with candles. Never leave burning candles unattended or use them near flammable items, children or pets. We use a butane lighter to light them and a snubber to put them out.

N-Gauge Loco Pictures

Thought that I would try some pictures with and without macro. Both taken with an iPhone6.

The subject is a Fleischman 1/160 scale n-gauge model train.

Lighting is a pair of LED household lights from Ikea and some reflective foil surrounding the subject. The iPhone is not using flash and not in HDR mode. The second picture uses a clip on macro lens on the iPhone to look at the front driving mechanism. Time for me to clean the track I think as you can see tiny pieces of lint that the wheels have picked up. These were taken freehand… they would probably be better if I clamped the phone. Still I am pretty happy with what can be achieved with not much prep on a phone camera.
