Place coriander and cumin seeds in heavy dry skillet, tossing occasionally over high heat. When seeds just start to smoke, remove from heat and pour onto plate to cool. Grind in mortar and pestle or electric coffee grinder. Combine cumin and coriander with other spices in small bowl. Grind peanuts in coffee grinder until they are the size of small crumbs. Add to spices. Add just enough sesame oil to mixture to form paste.
