Garam Masala

If the roses have stems, break them off and discard. Heat the roses with the cinnamon, bay leaves, cumin seeds, coriander seeds, cardamom pods, whole peppercorns, cloves, and chile in a medium skillet over medium-high heat, stirring often, until the cumin becomes brown, 2 1/2 to 3 minutes. Transfer to a spice grinder or coffee mill, add the nutmeg and mace, and grind until powder fine. Store in an airtight container for up to 4 months.
