I took my family to this Middle Eastern restaurant to celebrate my parents’ 33rd wedding anniversary, last June. Dishdash Grill had two different types of lassi on their menu- mango lassi, and salty (mint) lassi. It was the first time we’d heard about salty lassi! So yes, we had to order that!
Salty lassi is a Punjabi beverage that typically includes yogurt, (black) salt, mint, and cumin. I don’t remember what the pink/reddish topping ingredient was, maybe rose petal? But the drink was salty, mildly tart, and minty. It was a refreshing drink during the hot summer!
