How to make soy milk at home!
I joined the ranks of People Who Have Made Soy Milk At Home.
My first attempt yielded a pretty weak product, though it tasted good hot and both Sami and I enjoyed it. Combining info from five or six different sources on home soy milk making (without a machine), here is what I did:
1) Soaked one cup of dry beans overnight in about a quart of water. I replaced the water about once every 8 hours for 24 hours. I think this is longer than necessary, but it didn’t seem to do any harm.
2) Boiled the beans for about 30 minutes.
3) Ground up beans in the food processor with about one cup of (hot!) water for each 1/3 cup of beans.
4) Strained the milk through cheesecloth to remove the okara (bean pulp.) Squeezed the okara until it was more or less bone dry.
5) Added a tablespoon of honey and a pinch of salt to the quart or so of hot hot milk.
6) The end. Enjoyed a cup of hot, fresh soy milk. It was very weak (about 50% regular soy milk strength) but still tasty. Even Sami liked it.
The second attempt was much, much better. This time, I:
1) Soaked 2 cups of dry beans in 2 quarts of water overnight.
2) Microwaved the beans until they were heated through – about 3 minutes. I read on the internet somewhere that heating the beans before grinding them in hot water can reduce the beany soy milk flavor.
3) Ground up the beans, this time in the BLENDER (not the Cuisinart) for a finer grist. One cup of beans to about 3.5 cups of barely boiling water. I did this in four shifts before I got tired, and still have about a third of the beans.
4) Strain the blended stuff through clean cotton cloth. I skipped the cheesecloth and went straight to a 12 x 12 inch swatch of muslin. Since the grist was very fine and the cheesecloth I have is a loose weave, I figured this way I’d get better straining. I think I was right. Strain it until I’m satisfied that all the gooky parts are out. I did this twice.
5) Cook the milk. Low boil for 30 minutes. I scooped off all the little bits of foam that formed on top.
6) Serve hot with honey and salt as before – yum. Then pour the rest (about a gallon?) into a storage container – in my case a giant tupperware container with a pour-spout lid. I plan to get a glass pitcher with a sealing lid.
It wasn’t as hard as you’d think it would be, especially without a soy milk machine. I probably wouldn’t make this big a batch again, so in the future I won’t have to do the grind/strain dance so many times in a row. THe most time consuming elements were the soaking of the beans and the 30 minute milk cooking time. I can take save soaking time by putting them in the fridge a day or two before I want to make more, or always keeping a batch in there if I think I’ll make soy milk once a week or so. Not much to be done about the cook time, except perhaps to time it so that hot fresh milk is available when I want it.
I highly recommend doing this. It was (dare I say) fun! And I don’t think I’ll need to buy soy milk again. For the price of one carton of soy milk (or so) I got about a pound of beans, which I can use to make a whole case or more of soy milk. I don’t have to take home all those plastc-lined cartons! I don’t have to drink additives or preservatives or sugar! Unless I want flavor or sugar! Wheeeee!
