Mix everything and blend in a good quality blender.
Taste and add seasonings as needed.
Variations
Sweet Lassi: Sub 2 teaspoons or more sugar/sweetener for salt. You could also use honey, agave nectar, or your sweetener of choice.
Mango Lassi: Add I cup ripe mango cubes and 1/4 teaspoons cardamom. You could also use a few saffron strands if you're feeling fancy. Sometimes people add a tinge of rose syrup to this but I find it overpowers the mango flavor a bit.
Spicy Lassi: 2-3 thin ginger slices, 2 slices serrano chili and 1/8 cup chopped cilantro blended in. A squeeze of lime juice or lemon juice at the end is lovely.
Banana Lassi: 1 banana blended in, with some additional sugar if needed. Ground cardamom is delicious with bananas.
What The Heck Is This Yumminess Lassi: 1/2 teaspoons chaat masala (ready made)
Mint Lassi: 1/2 teaspoons dried mint whilst blending
Papaya Lassi: 1 cup papaya chunks and 1/4 teaspoons cardamom
You can use Greek yogurt for this, but you could also just use regular yogurt and add a little less water.
The final consistency of the drink, with added fruits, is like a thick pancake batter.
If you aren't adding fruits, then having a thinner consistency makes for a very refreshing drink.

I often use THIS VIETNAMESE YOGURT recipe and add mangoes to it for an EXTREMELY decadent but delicious dessert drink.
If you're adding fruit, plan to drink the lassi right away (Hardship, I know, but #SacrificeYourself).
Savory lassis usually do well in the fridge for 2-3 days at most.
