Lemongrass powder can be used in both cooking and baking to add a bright, citrusy flavor. In cooking, it's great for seasoning soups, curries, marinades, and broths, while in baking, it can be added to cookies, cakes, muffins, and other desserts to provide a unique twist. Its powdered form makes it easy to incorporate and evenly distribute the flavor without the fibrous texture of fresh stalks.
