you can make goat's milk yogurt (or soy or whatever you need) as well
I have a Salton incubator ($20) and add ultra homogenized milk (or boil and cool reg milk) and a few TBS yogurt (after 1st batch you use your own yogurt) and maybe a bit of powdered milk to bump up the calcium.
put in Salton and let sit for 4-36 hours depending on health benefits and tartness wanted. Add berries or jam before serving if you'd like
The benefits for gum/tooth disease ALONE are worth the effort!
