Yes, frozen curry leaves can be used for tadka, although they may not be as fragrant as fresh ones. Ensure they are completely thawed and patted dry before adding them to hot oil to prevent splattering.
Using frozen curry leaves in tadka (tempering) is a common practice, especially when fresh curry leaves are not readily available. The freezing process can slightly diminish the intensity of their aroma and flavor, but they still contribute a characteristic taste to the dish. Here's how to use them effectively:
Thawing: Before using, thaw the frozen curry leaves completely. This can be done by placing them in a bowl at room temperature for about 15-20 minutes, or by briefly microwaving them.
Drying: Once thawed, pat the curry leaves dry with a paper towel. This step is crucial because adding wet leaves to hot oil can cause excessive splattering, which is dangerous and can affect the cooking process.
Tempering: Heat your oil or ghee in a pan over medium heat. Add the other tadka ingredients like mustard seeds, cumin seeds, and dried chilies. Once the mustard seeds start to splutter, add the thawed and dried curry leaves.
Sautéing: Sauté the curry leaves for a few seconds until they become fragrant and slightly crisp. Be careful not to burn them, as this will impart a bitter taste.
Adding to Dish: Pour the tempered mixture over your dish to infuse it with flavor.
To maximize the flavor of frozen curry leaves, consider adding a pinch of asafoetida (hing) to the tadka. Asafoetida complements the curry leaves and enhances the overall aroma of the dish.
