It all starts with the spices:

• 3 tbsp chili powder
• 1 tbsp fine grind espresso
• 1 tbsp each: ground cumin, paprika and brown sugar
• 1/2 tsp each: salt, dry mustard, ground coriander, garlic powder, onion powder, oregano, red pepper flakes, and freshly ground black pepper
• 1/4 tsp cayenne
• 1 tbsp brown sugar

Add all of the above to a small frying pan, except for the brown sugar. Turning the spices often, heat over a low flame until the spice mixture begins to turn a darker shade of red. This is called "blooming" the mixture. It brings out the oils in the spices and turns up the flavor.

If you see any wisps of smoke, remove immediately - burnt spice isn't the smokey flavor you're after.

Transfer the spice mixture to a bowl and stir in the reserved brown sugar, mixing well.

At this point, your entire kitchen will smell wonderful.
