How to Dry Roast Whole Spices Without Burning Them

Dry roasting whole spices before grinding makes a masala smell deeper and rounder. It also dries out any moisture, so the powder grinds finer and keeps better. But it takes about 10 seconds to go from perfect to burnt. This is how to get it right without losing a batch.

What you need

• A heavy-bottomed pan or cast-iron kadai. Thin pans get hot spots and burn spices.
• A spoon or spatula to stir constantly.
• A plate ready to tip the spices onto.

Method

1. Start on low-medium heat. Warm the empty pan for a minute.
2. Add bigger, harder spices first: cinnamon sticks, cloves, star anise, peppercorns. Stir for 1 minute.
3. Then smaller seeds: fennel, cumin, coriander. These roast faster.
4. Cardamom last, or lightly, for 20 to 30 seconds. It's delicate, and over-roasting dulls its bright smell.
5. Keep stirring. Don't walk away.
6. Stop when the spices smell strongly and seeds turn a shade darker, usually 2 to 4 minutes in total.
7. Tip onto a plate immediately. Spices keep cooking in a hot pan even after you turn off the heat.
8. Cool completely before grinding.

How to tell when they're done

• Smell: the clearest sign. Your kitchen will suddenly smell of the spices.
• Colour: cumin and fennel go a shade darker, not black.
• Sound: some seeds start to pop lightly.
• Smoke: a tiny wisp is the limit. If you see real smoke, you've gone too far.

If you burn them

Start again. Burnt spices taste bitter and acrid, and that bitterness spreads through whatever you cook. It's not worth saving.

Do all spices need roasting?

• Yes, usually: cumin, coriander, fennel, dry red chillies for masalas.
• Lightly, or not at all: cardamom, especially for sweets and chai. Its fresh smell is best raw.
• Optional: cloves, cinnamon, pepper. A short warm-through helps them grind.

Roast small, roast often

Roasted and ground masala loses aroma fastest of all. Make what you'll use in two or three weeks.
