Toast the coriander seeds, cumin seeds, black peppercorns, cardamom, cloves, and cinnamon in a dry skillet over medium heat until fragrant, about 2-3 minutes.
Remove from the heat and let cool completely.
Grind the spices in a spice grinder or mortar and pestle until they become a fine powder.
Store the Garam Masala in an airtight container in a cool, dark place.
Notes
For a more intense flavor, toast the spices for a few minutes longer.
You can adjust the proportions of the spices to your liking.
Garam masala can be stored in an airtight container for up to 6 months.
Here are some ideas for using Garam Masala:
Add it to curries, stews, and soups.
