This classic blend of spices is essential in Indian cuisine.
Makes 1 3/4 Cups
1/2 cup cumin seeds (optional)
1/2 cup coriander seeds
1/4
cup black peppercorns
1/4 cup cloves
4 cinnamon sticks
1 tablespoon freshly ground cardamom seeds
1. In a hot skillet over medium heat, toast all the ingredients except
the cardamom seeds for 2 to 3 minutes, stirring or shaking the pan
constantly.
2. Turn off the heat, stir in the cardamom seeds, and continue to stir
the mixture for 1 minute.
3. Remove the pan from the heat and grind all the spices together in a
spice grinder. Garam Masala will keep indefinitely in a tightly closed
jar, although the spices will get weaker after 6 months.
