Technique #2: Bloom Spices for Depth and Complexity

Simply put, blooming uses heat to awaken the dormant flavors of spices by cooking them in fat before proceeding with a recipe.

Spices contain a host of flavor compounds that give them their character and complexity. Many of these flavor compounds are fat-soluble, so briefly cooking the spices in fat changes these fat-soluble flavor molecules from a solid state to a liquid one. In a liquid state, they can more effectively interact with other ingredients in the dish to create more intense and complex flavors. Since you’d need to add the spices to the pan at some point anyway, it doesn’t amount to any extra work.

Spice blends or dishes that use multiple spices particularly benefit from the blooming technique; for example, dishes from the cuisines of Mexico, the Middle East, North Africa, and India. If you’ve ever made a curry or a chili, you may have bloomed spices without even realizing it. 

Just dumping and stirring a curry paste or a mix of powdered spices into the pot will result in a curry or a chili with a bland, musty flavor or texture, but cooking the curry powder or paste or the chili powder in fat before introducing other ingredients will bring out its warm notes and multi-layered flavors.

Blooming isn’t typically a long process. Ground spices and spice pastes bloom at different rates, so depending on the dish and the ingredients, it can take anywhere from 30 seconds to several minutes. Do be careful not to apply too much heat to your spices or heat them for longer than recommended; ground spices will burn fairly quickly, resulting in a scorched flavor in your finished dish.
