To prevent curry leaves from burning during tadka, add them towards the end of the process, after the other spices have tempered, and ensure the oil isn't too hot.
Tadka, also known as tempering, involves heating oil or ghee and then adding spices to release their flavors. Curry leaves, being delicate, can burn quickly if added to very hot oil or cooked for too long. Here's a step-by-step guide to prevent burning:
Heat the Oil Gently: Start by heating your oil or ghee over medium-low heat. You want it hot enough to temper the spices, but not so hot that it instantly burns them.
Add Harder Spices First: Begin with spices that take longer to release their flavor, such as mustard seeds, cumin seeds, and dried red chilies. Allow them to sizzle and pop.
Reduce the Heat (If Necessary): If you notice the spices are browning too quickly, reduce the heat further or even take the pan off the heat for a few seconds.
Add Curry Leaves Last: Add the curry leaves towards the end of the tempering process, after the other spices have had a chance to release their aroma. This minimizes their exposure to intense heat.
Briefly Sauté: Sauté the curry leaves for just a few seconds, until they become fragrant and slightly crisp. Be careful not to overcook them.
Immediately Add to Dish: Pour the tadka over your dish immediately after the curry leaves are added. This stops the cooking process and prevents them from burning.
Ensure your curry leaves are completely dry before adding them to the hot oil. Excess moisture can cause the oil to splatter and also contribute to uneven cooking, potentially leading to burning. Pat them dry with a paper towel before use.
