Kind of off topic, but just for reference, you can make soy yogurt from unsweetened soy milk using a regular dairy yogurt recipe and starter. Sweetened soy milk won't culture. Homemade is obviously best, but you have to do it hands-on - those machines make really thin milk that's no good for yogurt. I usually just buy unsweetened Eden soy milk (yeah, the packaging and shipping, I know ). It's still way cheaper and uses a lot less plastic than buying prepared soy yogurt.
