I haven’t done any tutorials since I moved into this home, so I figured it was time to do one. This method of making soy concentrate is going to be the basis for the next two recipes. Keep in mind that you could use it to make soy milk (by adding twice the water), but that is just too much work, in my opinion, especially when I have a soy milk machine. But I can’t use it to make small quantities of concentrate, so this is what I do when I need some.
First, you will need to soak soy beans. This is 1/2 cup of dry, organic Laura soybeans (the second best price and the best quality I have found), soaked overnight.

It is essential to think ahead for any recipe using soy concentrate. I suppose if you had some soy milk powder that didn’t have vanilla in it, you could double the amount of powder, but it would cost a whole lot more. I don’t happen to have any soy milk powder in the house! I either plan ahead or do without.
Once the soy beans are ready, bring about two quarts of water to a boil. When it’s just about boiling, turn on the hot water on, and when it’s hot, put the soy beans under it to rinse and heat up. The water should not be on strong enough to make the beans spill out.

If you time it right (which I never do, just so you know), the water should be boiling now (mine’s usually been boiling for 5 or 10 minutes). Fill your blender with the boiling water to warm it. Glass blenders are best, because they retain the heat longest. It will warm quickly—probably 30 seconds or less, and you want the water to be as hot as possible. Now get a strainer and pour your beans into the strainer, then quickly dump the water from the blender over them.

Now rapidly dump the beans into the hot blender and add 2 cups of the boiling water. Blend. Be careful not to start the blender on high, or at best you could have a very hot mess all over. ***Here’s how I like to start it. You’ll want to blend about 2 minutes.

I should make a comment on the reason for all that effort, as opposed to just rinsing the beans and blending in water. There is an enzyme in soybeans that is activated when the bean is broken. This enzyme is what gives homemade soymilk its “beany” flavor—the flavor that store-bought soy milk does not have. However, the enzyme can be killed before it reacts if the water is hot enough. That’s why we heat the beans, the blender, and then blend in boiling water. Soymilk made this way tastes better than anything my soy milk machine can make—it just takes too much effort to make it! Maybe when all my kids are grown and gone. . .
Let it blend for a couple of minutes. You want it very fine. Now, pour it into a 2-quart saucepan and slowly bring to a boil. I say slowly, because it’s already very hot, and soymilk will boil over very quickly (as it nearly did in the picture below while I toyed with the camera settings!), so you need to watch it. I stir with a rubber spatula, so I don’t scratch the bottom, but also try to prevent it from building up. You could use a double boiler and let it go 15-20 minutes (it probably won’t boil over then), but that uses more energy.

I cooked it with the fiber in it because it was just too hot to strain. If I were making soy milk, I would strain it out as best I could with the spatula, then put the pulp back in the blender with cold water, blend briefly, then I would strait it out well. But I’m making concentrate, not milk, so I am not adding water. Now I let it cool in the fridge. Within a couple of hours, it will be cool enough to strain through a cloth, but not too cold.

This should make 2 cups of concentrate. If it isn’t quite enough, top the jar off.

Make sure your concentrate is thoroughly chilled before using in recipes, unless it calls for hot concentrate. It should be chilled for making next week’s recipe, as well as mayo or similar recipes.
You could also use this in recipes calling for evaporated milk. You would want to add a little sugar to sweet recipes, like pumpkin pie, though for savory dishes, like creamy soup, you wouldn’t want to. Be sure to add an extra dash or two of salt to the recipe, especially if it is initially a tad low in salt, because this doesn’t have the salt content that store-bought soy milk does. Also, keep in mind that if you are going to cook it, you can skip the cooking in saucepan step; just chill in the blender (in the fridge—it cuts down on bacteria growth), strain, and use. But use within a day or two, because uncooked it won’t last very long.
Next week I’m going to share my recipe for a soy base that can be used to make anything from sour cream to sweet whipped cream to mayo.
Note: I got this method from the cookbook Oats, Peas, Beans, and Barley, but I did not copy their text. I have made the recipe so many times that I just wrote it from memory, so I don’t think I’m breaking any copyright laws. But their book does have some excellent recommendations on using it, and I highly recommend it.
