I like the way my mom fixes them which is baked with herbal seasonings. Lambchops aren't very suited for frying, grilling, or broiling because they are so small and even a little overcooking can make them pretty nasty. Greenish tint? was that before or after you applied the mint jelly
seriously meat should never be green.
Lamb is more pungent than beef, and faintly liver like but not much (of course I like liver). If you really want to try out lamb do a leg of lamb first as lamb chops can be tricky to cook and frankly you don't get much reward for all the prep time.
