Tadka is a popular cooking technique in Indian cuisine that involves tempering spices in hot oil or ghee. This process enhances the flavors and aromas of the spices, making the dish more flavorful. Common spices used in tadka include cumin seeds, mustard seeds, and curry leaves, which are often added to the oil until they crackle and release their essential oils. Typically, tadka is added to lentil dishes, vegetable curries, or rice preparations. The sizzling sound and fragrant aroma created during the tadka process are key indicators of its readiness. This technique is essential for many traditional Indian recipes, contributing to their unique taste and character.
