Yes, you can temper with whole spices only. Tempering is a technique that involves heating spices in oil or ghee to release their aroma and flavor, and whole spices work perfectly for this.
Tempering, also known as 'tadka' or 'chhonk,' is a crucial step in many cuisines, especially Indian cooking. The process involves heating oil or ghee in a pan and then adding whole spices. As the spices heat up, their essential oils are released, infusing the oil with their aroma and flavor. This flavorful oil is then added to a dish, often at the end of cooking, to enhance its overall taste. Whole spices like cumin seeds, mustard seeds, dried red chilies, cloves, cinnamon sticks, and cardamom pods are commonly used for tempering. The heat helps to unlock their complex flavors, creating a richer and more nuanced taste profile in the final dish. The visual appeal of the whole spices also adds to the dish's presentation.
Be careful not to overheat the spices during tempering, as they can burn quickly and become bitter. Start with medium-low heat and watch the spices closely, removing the pan from the heat if necessary to prevent burning.
