It’s actually really easy, and you don’t need a yogurt maker.
Ingredients:

• 1 Liter of soy milk
• 1 Tbsp of sugar (if using unsweetened soy milk)
• 2 Tbsp of “live” yogurt (soy or milk-based)
• 1 Liter glass jar and lid
• 1 metal spoon

Instructions:

1. Boil some water and scald the spoon and the glass jar
2. Bring the soy milk and sugar to a boil
3. Remove the soy milk from heat and let it cool down just enough so that it’s not painful to touch
4. Mix the yogurt into the soy milk
5. Pour the soy milk into the glass jar and cover
6. Put the glass jar in a warm place like a hot water cupboard or a gas stove with the pilot light on
7. Wait 8-12 hours.
8. Remove the soy “yogurt” from the warm place – it should now look like yogurt!
9. Chill in the fridge before serving

A couple of disclaimers:

• This recipe results in a very mild, creamy soygurt that is less nutty than the yogurts I’ve tried by Alpro and Sojasun (a good thing, IMHO)
• I used Whole Foods’ organic unsweetened soy milk
• I tried this for the first time over the weekend; it has yet to be seen whether future attempts will be as successful
• If you’ve had soy milk, then you know it doesn’t really taste like real milk. Same goes for soy “yogurt”, so don’t try to pretend it’s anything else
• People who like cow’s milk yogurt will probably not like soy yogurt, so don’t get too upset when they cringe at the flavor
• This yogurt tastes best when paired with something tasty like fruit or Bircher Muesli
• This vegan lady uses the stuff to make “Greek-style” soy “yogurt” and vegan “cheese” – it looks pretty good, even if it’s not really cheese
