We fell in love with the Mango and Strawberry Lassis at the Bombay House and at Royal India. We've tried a couple recipes that called for 3 C yogurt and 1 C fruit and they just weren't right! Then, I saw a drink recipe in a kids' cook book proportioned this way, and it tasted so much better!
3 1/2 C fruit*
1 C yogurt (full-fat tastes best!)
1/4 C sugar*
1/2 - 1 C milk
ice cubes (8?)
Put all ingredients in a blender except for ice. Blend. Add ice, blend.
I use 1/4 C sugar for apricots, a little less sugar for sweeter fruits.
