I got the recipe for this spice blend from the book 'Spice Market' essential information on spices, spice mixes and spice pastes by Jane Lawson. It is a beautiful book. I intend to use this blend for chicken.
You will need
3 tablespoons coriander seeds
1 1/2 tablespoons cumin seeds
1 teaspoon fennel seeds
1/4 teaspoon fenugreek seeds
2 cm cinnamon stick
1/4 teaspoon cardamon seeds from green pods. Crack open the pods
2 dried chillies
2 teaspoons dried curry leaves ( I didn't have these so I didn't put them in)
Gently dry-fry them on low heat in a heavy based bottom pan until fragrant about 3 mins. Don't let them brown too much or it will become bitter and awful and a waste of time.
I started to pound in a mortar and pestle but it was going to take too long, so I used the electric spice grinder instead which only took seconds.
