Consult couscous package to find out how much water is required for cooking. (Usually it's a 1:1 ratio of couscous to water.) Place the water in a medium saucepan; add curry powder, salt, cumin, ancho pepper, paprika, sugar and cinnamon. Bring to a boil. Stir in oil. Turn off heat and stir in couscous. Cover with a tight-fitting lid. Let stand 5 minutes.
