Lemon leaves give off a beautiful fragrance when torn. Indeed, they can be used to form a grill bed or as a grilling wrapper, lending their fragrance to grilled foods. Don’t chow down on a handful of them, though. “I treat them just like lemongrass,” says Cheese Boy, “... a quick lick and perhaps a bite or two to release any of the oils that still remain, and then they’re placed on the rim of my plate.”
One other thing. You know those lime leaves you can buy from Thai grocery stores that are called for in Thai stir-fries? Those are different from other lime tree leaves, says torty. They’re from kaffir limes and are odd-shaped twin leaves. Don’t eat your lime tree.
