Tips & Warnings
The quantity of milk you use will produce the same amount of yogurt. You don't have to use cow's milk--you can replace it with goat's milk, soy milk or rice milk. You will need to use plain yogurt containing L. Bulgaricus for the starter batch; for subsequent batches you can use a starter from your own yogurt Use a plastic spoon because it's easy to sterilize.
