In a small dish, combine the lemon juice, lemon zest, parsley, cumin, coriander, cinnamon, salt, and pepper to make a paste.
In a large bowl, mix together the lamb with the spice paste. Form into 8 patties and place on a greased broiling rack over a baking sheet or broil pan (you want to have the burgers on a rack so that the baking sheet can catch drippings).
Broil burgers about 6 minutes per side for medium rare.
