Whole spices
- Flavour oil or ghee in a tadka, or rice in pulao and biryani.
- Release their flavour slowly, so they suit long cooking.
- Keep for about a year.
Ground spices
- Disperse evenly through gravies, marinades and dry dishes.
- Burn quickly in hot oil: add them with onions or tomatoes, or with a splash of water.
- Lose their aroma in a few months.
Roasting and grinding at home
- Dry-roast whole spices in a heavy pan on low to medium heat, stirring, until they smell toasty and darken by a shade. Larger, harder spices (coriander, dried chillies) take longer than small ones (cumin, fennel), so roast them separately.
- Spread on a plate to cool completely. Grinding warm spices makes a damp paste.
- Grind in a spice or coffee grinder kept only for spices. A mortar and pestle works for small batches.
- Sieve for a fine powder and grind the coarse bits again.
Freshly ground cumin and coriander taste noticeably brighter than shop-bought powders. Try our blend recipes, which you can scale to any batch size.
