I received this soymilk maker for my birthday: http://www.amazon.com/Soyapower-Plus-Milk-Maker-Rice/dp/B001KT61P8/ref=sr_1_1?s=home-garden&ie=UTF8&qid=1322017157&sr=1-1 I wanted to make homemade soymilk because it is so expensive at the store. $3 for a half gallon of organic soymilk. Wow! It really adds up. Also, I wanted to try making dubu myself after seeing someone else post about it on her blog. http://www.lafujimama.com/2009/09/how-to-make-tofu-no-fancy-equipment/
So, I've made a few different kinds of soymilk now. Plain soymilk, milk made with half garbanzo beans and half soybeans and black soybean/black sesame seed soymilk (my favorite). I love how my homemade soymilk has less sugar than the store brands. My kids of course prefer the store brand because it is sweeter, so I am working on them still. I will probably just sweeten theirs with stevia.
The dubu has turned out really well too. It is surprising to see how much whey is left once the soymilk coagulates. It takes like 4 batches of milk to make a block of dubu. But it tastes really good and fresh. I told my husband that now I can open up a booth at the farmer's market selling artisan dubu.
Next on the agenda is to get some malt powder because it is supposed to make the soymilk taste more like the store brands. And then I want to make some almond milk because my soymilk maker can make all kinds of nut milks. So cool!
The soymilk maker cost $120 and for me it is worth it. I make soymilk twice a week now and the ingredients are so cheap. We still buy dubu, because it is more labor intensive to make, but I'm not buying soy or nut milks anymore.
