Until fragrant

"Until fragrant" tells you to cook an ingredient briefly, only until it gives off a strong, pleasant smell. Recipes use it for garlic, ginger, ground and whole spices, chili flakes, curry paste and toasting nuts or seeds. It is a short step, often 30 seconds to 2 minutes. Its job is to release flavor into the oil before the next ingredients go in.

How to do it

1. Heat the oil or butter over medium heat. It should shimmer but not smoke.
2. Add the ingredient and stir all the time.
3. Smell the pan. Use these times as a guide:
   • Minced garlic and ginger: 30 to 60 seconds.
   • Ground spices: 30 to 60 seconds. See bloom.
   • Whole spices like cumin seeds: 1 to 2 minutes, until they crackle.
   • Nuts and seeds in a dry pan: 2 to 5 minutes. See toast.
4. As soon as the smell fills the air, add the next ingredient or take the pan off the heat.

How to tell it is done

• You can smell it clearly from a step away from the stove.
• Garlic is pale gold at the edges, not brown.
• Spices darken one shade and may sizzle or pop.
• Nuts look a little darker and shiny with their own oil.

Why it works

Many of the flavor compounds in garlic, spices and nuts dissolve in fat and are released by heat. A short burst in hot oil carries them into the fat, which then coats the whole dish. Too much heat, though, turns these compounds bitter and burnt quickly.

Common mistakes

• Adding garlic at the same time as onions. The garlic burns before the onions soften. Add it near the end of the onion step.
• Walking away. Spices and garlic go from fragrant to burnt in seconds.
• Heat that is too high. Lower it before adding ground spices.
• Carrying on with burnt garlic. It makes the whole dish bitter. Wipe out the pan and start again.

In recipes

"Cook until fragrant, about 30 seconds" is common in stir-fries, curries and pasta sauces. "Until aromatic" means the same. For a dry pan of nuts or spices, "toast until fragrant" is the usual phrase. Many dishes start with a soffritto and then add garlic until fragrant.
