This one is of medium strength, and has good all-round taste.

For those who like their curries with a punch.

63g (4 oz) coriander seeds
44g (1.5 oz) ground turmeric
25g (1 oz) ground cinnamon
125g (4 oz) dried red chilies
13g (0.5 oz) whole black peppercorns
32g (2 oz) cumin seeds
13g (0.5 oz) ground cardamom

To make the powder, Use an electric coffee grinder, grinding a small part of the seeds at a time, then mixing the ground and preground spices in a bowl. Both recipes make enough for a large jar. Clean the coffee grinder thoroughly after (grind some stale bread in it or something like that).

The powder is not as fine as commercial curry powder. You can sieve the powder to remove the remaining pieces of husk. Store in an airtight jar somewhere cool.
