Hi, I've been venturing down the Yogurt road and have seen that you can make yogurt starter using Just green cardamom seed pods or even Chili peppers? I've even some using Lemon juice or slices. I can see how Lemon would Curdle milk, but is that really a Yogurt Starter? How exactly do Cardamom, Chilis or even lemon make Yogurt starter? Do they really add bacteria? Do they contain L. bulgaricus or S. thermophilus on their surfaces? Is it some other bacteria? I've been searching for days and find Nothing. Does anyone know?
TIA
