Wash and pit 250 grams of fresh cherries. Set aside a few cherries for garnishing.
In a blender, add the pitted cherries, 500 grams of chilled plain yogurt (dahi), 100 grams of sugar, and 1/2 teaspoon of cardamom powder. Blend until smooth and creamy.
Taste the lassi and adjust the sugar according to your preference. If the lassi is too thick, add a little cold water or milk to adjust the consistency.
Pour the cherry lassi into serving glasses. Garnish with the reserved cherries and a sprinkle of cardamom powder.
Serve the cherry lassi chilled.
