In a small skillet, combine cumin, coriander, fennel, fenugreek,
peppercorns, and mustard seeds. Over medium heat, stir and swirl the
spices until fragrant, about 30 seconds. Transfer whole spices to a
spice grinder and grind to a fine powder. Empty into a small bowl
and combine with turmeric, garlic powder, and cayenne pepper.
