HELLO

This makes about three tablespoons.

1     tablespoon coriander seeds
1     tablespoon cummin
1     teaspoon green cardamoms
1     teaspoon cloves
1     teaspoon black peppercorns
2     sticks of cinnamon, approx two inches in length
2     bay leaves
½     small nutmeg
4     black cardamoms
Place all ingredients into an electric coffee grinder and grind for one minute. Carefully remove lid and test by rubbing a little of the mixture between forefinger and thumb. Finely ground spices should not feel gritty. If necessary, switch on the machine for another few seconds.
Put the garam masala into a small airtight container, preferably made of glass or plastic, and label.
