Friday afternoon I made 3 Liters of Soy Milk
(which now I can say in retrospect... that was waaaay too much).
At any rate, the process making of soy milk is pretty simple:

Put the soy beans in water for 8-12 hours
(I just put them and forget about it for a day),
Put them in the blender with water in the ratio of 1/2.5
(1 cup soy, 2.5 cups water, or 2? or 3? just try it and see),
Then cook the mix until it boils (very recommended, makes it easier to strain afterwards), Wait until it cools down and strain it through a cloth (I use a kitchen towel).

During the cooking process you can of course add a Vanilla stick or Cinnamon or whatnot.

Once you strain the soy milk, the leftovers you have
(the pieces that didn't make it through the strain)
are called Okara, which is a very useful ingredient as it has many, many recipes online.

In my case, I decided to make sort of an Okara-Burger, followed no recipe by the way.

I used:
1 Jar of Okara (2-3 Cups)
1.5 Cups of Tomato Sauce (basically tomatoes, olive oil, garlic, and a chilli pepper)
2 Onions
2 Garlic Cloves.

After chopping the onion and garlic, I just mixed everything up,
made small patties and put them for 15 minutes in an oven (250 degrees)
It was delicious! Although very breakable they do have a texture resembling meat..
I think it should be a lot more similar if making a Bolognese sauce

p.s.
Because I ate everything too quickly, I forgot to take a picture of the burgers :I
The picture on the post is the most similar thing I could find
Next time I'll be patient, I promise!
