Fresh herbs like cilantro or mint should be added to a curry at the very end of the cooking process, just before serving, to preserve their delicate flavors and vibrant color.
Adding fresh herbs at the end of cooking ensures that their volatile oils, which contain the aromatic compounds responsible for their distinct flavors, are not lost due to prolonged heat exposure. If added too early, the heat will degrade these oils, resulting in a muted and less impactful flavor. Furthermore, the vibrant green color of herbs like cilantro and mint will fade and become less appealing if cooked for an extended period. By adding them right before serving, you maximize both the flavor and visual appeal of your curry. Simply stir them in gently and serve immediately. This allows the herbs to infuse the dish with their fresh, bright notes without becoming wilted or losing their potency.
Avoid chopping the herbs too finely if you're adding them right before serving. Slightly larger pieces retain more moisture and flavor, preventing them from drying out and becoming bitter. A rough chop is ideal for maximum impact.
