Trim excess fat off the lamb chops. Combine the lemon juice, salt, olive oil, mint and pepper. Marinate the lamb in this mixture in a flat dish, turning often, for at least 30 minutes at room temperature or longer in the refrigerator.
While lamb is marinating, prepare the compound butter. Cream the butter with the lemon juice, mint and salt and pepper to taste. Place the butter on a piece of waxed paper and shape into a cylinder (about 3 x 1 1/2 inches). Refrigerate.
Broil, barbecue or pan fry the lamb chops approximately 3 to 5 minutes on each side (they should be slightly rare). Slice the butter thinly and place two slices on each hot chop.
The butter will melt slowly and moisten and flavour the lamb. Lower-fat Version: Use only a very thin slice of the lemon butter, or omit it entirely.
