Khatti Keri is a sour raw mango pickle prepared with mustard oil and traditional spices, capturing the natural tartness of the unripe fruit. It’s tangy, mildly spicy, and packed with bold flavors that develop over time. Best served with parathas, rice, or khichdi, this pickle delivers the perfect balance of acidity and heat. A nostalgic summer favorite, Khatti Keri is simple yet deeply satisfying.
