Blend the Base: In a high-speed blender, combine the fresh coriander, mint leaves, green chili, chopped cucumber, and fresh ginger.
Add the Cream & Spice: Drop in the yogurt, sattu powder, roasted cumin powder, black salt, and pour over the chilled water. Blend on high until everything is completely liquified, smooth, and beautifully vibrant green.
Prep the Glasses: Grab two tall glasses and place a generous handful of ice cubes at the bottom of each.
Layer the Seeds: Divide the plump, gelatinous soaked sabja seeds evenly between both glasses, layering them right over the ice.
Pour & Serve: Pour the chilled savory buttermilk over the seeds, give it a gentle stir to mix, and finish with a tiny pinch of roasted cumin powder on top for that perfect aromatic touch. Drink fresh and enjoy the instant cool down!
