Whole spices like cumin seeds, mustard seeds, and dried red chilies release their aroma quickly during tempering, while ground spices such as turmeric, coriander, and chili powder require a longer time to bloom in the hot oil.
Tempering, also known as 'tadka' or 'chhonk,' is a cooking technique where spices are briefly heated in hot oil or ghee to release their essential oils and aromas. The order in which you add spices significantly impacts the final flavor profile of the dish.
Quick-Releasing Spices: These spices have volatile oils that are easily extracted with heat. Adding them first ensures their aroma infuses the oil before other ingredients are added. Examples include:
Slower-Releasing Spices: Ground spices need more time in the hot oil to fully bloom and prevent a raw or bitter taste. They are typically added after the whole spices have released their initial aroma. Examples include:
The timing is crucial. Adding ground spices too early can cause them to burn, while adding them too late might not allow their flavors to fully develop.
Always keep the heat on medium-low when tempering spices. High heat can quickly burn the spices, resulting in a bitter and unpleasant taste. If the spices start to darken too quickly, immediately remove the pan from the heat.
