Raw mango-berry syrup, chili, kala namak & sparkling water
Kala khatta translates to 'dark sour' — the color and flavor of the syrup made from raw mango and karonda berries. It's the defining taste of Mumbai's Juhu Beach vendors. The salted rim is mandatory.
Kala khatta syrup is a dark purple concentrate — brands like Lala's are reliable. The drink should taste aggressively tangy and salty with a sweet undertow. If it tastes flat, add more kala namak.
