This is normally drunk with every meal. It helps in the digestion. It also keeps you really healthy.
For this you need 2 cups of water, half a cup of plain yogurt, half a teaspoonful of cumin seeds, or powdered cumin seeds, 1 inch piece of fresh ginger, one tablespoonful of cilantro/mint leaves, chopped up into pieces, and pinch of salt.
Put all the ingredients together except the cilantro into a blender and blend until the buttermilk is foamy. Garnish with cilantro and put in the jug, so that your whole family can pour it out, when they have finished their lunch or dinner. If you want sweet buttermilk, you can add 2 tablespoons of honey. Once I put in half a teaspoonful of ground cardamom and half a teaspoonful of fresh grated ginger in this buttermilk and found it really refreshing and tasty. That was spicy buttermilk!
