ASTUCE: I suggest toasting cumin seed in a small skillet on the grill, alongside your burgers or other foods that are grilling, then grinding them in a spice grinder, or in a mortar and pestle. Also, if you want your sauce more spicy, you know what to do (hint: add more spices!).
SPECIAL EQUIPMENT: small, heavy skillet and spice grinder, whisk
PREPARATION TIME: 10 minutes
DIFFICULTY LEVEL: simple
