Lemon juice enhances flavor in curries by adding brightness, acidity, and a fresh citrus note that balances richness and spices. It also helps to tenderize meat and vegetables.
Lemon juice works wonders in curries through several mechanisms. First, its acidity cuts through the richness of the fats and oils often used in curry preparations. This prevents the dish from feeling heavy or greasy on the palate. Second, the bright, citrusy flavor of lemon juice adds a refreshing top note that complements the complex blend of spices. It elevates the overall flavor profile, making it more vibrant and appealing. Third, the acid in lemon juice can help to tenderize proteins, especially when added during the cooking process. This is particularly beneficial for tougher cuts of meat or vegetables that require longer cooking times. Finally, lemon juice can help to preserve the color of certain vegetables, preventing them from browning or discoloring during cooking.
Add lemon juice towards the end of the cooking process to preserve its fresh flavor and avoid it becoming bitter from prolonged heat exposure. A squeeze right before serving is often the best approach.
