How to Fix an Overly Sour Curry: Chef Secrets for Tomato, Tamarind & Dahi Balance
Master the culinary science of balancing excess acidity in Indian gravies using caramelized onion reductions, dairy fats, jaggery, or alkaline buffers without diluting spice integrity.
The Root Causes of Acidity in Indian Cooking
Curry acidity typically stems from four culinary culprits:
1. **Uncooked Raw Tomato Flesh**: Adding raw tomato puree without cooking it until oil separates (*bhunao*) leaves malic and citric acids raw and harsh.
