How to Toast Whole Spices
Raw spices often taste flat because their aromatic compounds are dormant. A few minutes of steady heat changes the internal structure, making the flavor deeper and more complex before you grind them into a curry or rub.
Use your nose, not your timer.
The window between perfectly toasted and burnt is thin, so stay at the stove and keep the spices moving constantly.

The aromatic threshold
The moment you can identify the scent of the spice across the room, it is ready. If you see wisps of smoke or the spices begin to turn black, they have scorched and must be discarded.
The method.
Heat the pan
Place your skillet over medium-low heat. Do not add oil or fat; the pan must be bone-dry.
Add the spices
Pour the whole spices in a single layer. Spread them out so they have even contact with the metal.
Keep them moving
Use your spatula to stir or shake the pan constantly. You want every seed to tumble and heat evenly.
Cool immediately
As soon as they are fragrant and a shade darker, pull them off the heat and dump them onto a cool plate. If you leave them in the hot pan, the residual heat will turn them bitter.
When it doesn't go to plan.
Always toast whole spices rather than pre-ground powders; ground spices burn in seconds.
If you are toasting different spices with different sizes, toast them separately, as mustard seeds will finish much faster than cinnamon sticks.
Let the spices cool completely before grinding them into a powder to keep your spice grinder from getting gummed up.
The ones that keep coming up.
How do I know if I have burnt them?
Burnt spices smell acrid and charred rather than fragrant. If they taste bitter or have black spots, start over.
Can I toast a large batch at once?
It is better to work in smaller batches. If the pan is crowded, the heat won't penetrate evenly, leading to raw centers and burnt edges.
