Garam masala and curry powder are both spice blends commonly used in Indian cuisine, but they have some differences. Garam masala typically contains a smaller number of spices compared to curry powder, and it is often used towards the end of the cooking process to add flavor to a dish. Curry powder, on the other hand, is a blend of spices that can include more than 10 different ingredients, including cumin, coriander, turmeric, and chili powder.
