Heat a dry skillet over medium-high heat. Add the cumin, allspice, coriander, cloves and cinnamon stick and cook, stirring, until fragrant, about 3 minutes. Transfer to a plate and cool completely. Grind in a spice grinder, mortar and pestle or blender.
In a small bowl, combine the ground spices with the ginger, salt, black pepper, cayenne pepper and turmeric. Keep in an airtight container up to 2 months.
Note: Ancho chiles are dried poblanos. Try sprinkling a little of this chili powder on grilled corn that's been brushed with a bit of olive oil. Finish off with a squirt of fresh lime juice for an interesting twist on summer's favorite veggie. From Meredith Deeds.
