K2, I made regular cow milk yogurt and it came out great! Even my husband who eats yogurt a lot liked it (with blueberries added to sweeten it). I actually tried eating a little bit and it tasted good. I didn't feel any worse after eating it, but that might be because I was feeling pretty bad and bloated to begin with, with or without yogurt. So I can't say if it affected me in any way. Once my gut settles I will probably try it again. Here's how I made it - I microwaved 32oz of milk to simmering temperature and let it cool down to 110 F. It's important to heat the milk because otherwise it may not ferment properly. Then I took 1/4 cup of store-bought, full-fat yogurt (I used low-fat milk) because this kind doesn't have pectin which might hinder yogurt production. I mixed it with a little bit of milk and added it to the rest and put it a plastic container with a lid. Then I filled a hot water bottle with hot water. I took a thick blanket, wrapped around the bottle and then sat the container on top and wrapped around one more time. Waited 24 hours and then without stirring I put the container in the fridge to settle. Then it's OK to stir. That way the yogurt was fairly thick and had a really good flavor. I've never tried this with non-dairy milk but I think it should work. I would just make sure that particular type of milk has enough sugar (or add a little) so that the bacteria can feed on it.
