It is important to use "hot" paprika in this recipe, to create the spicy red-chile coating for the lamb chops. Paprika, finely ground dried red-pepper pods, can vary in intensity from mild to pungent; most supermarkets only carry the mild variety. The lamb chops must marinate overnight or up to 3 days before grilling.
Garam masala is an Indian spice blend available in specialty stores and some supermarkets. To make your own, mix together 1/2 teaspoon each of ground pepper, cinnamon, cardamom, cumin, and coriander, along with a generous pinch of cloves.
A simple, chilled herb sauce cuts through the richness of grilled lamb chops for a summery, yet satisfying, entree. Shoulder chops, an inexpensive cut that's rich in flavor, are available at most major supermarkets.
