Why don't they simply raise lamb in fields of mint, saving us the trouble?
Well, the answer is probably because making your own mint sauce is fun, easy, and quick. That artificially-colored sweet mint jelly from the supermarket is to real mint sauce as canned cranberry jelly from the supermarket is to fresh homemade cranberry sauce.
Since everyone's garden mint is probably growing like crazy right now (but not up here, yet - is mint an herb or a weed?), here's the right way to make mint sauce for lamb. Make it when the mint is new, and it will last at least all summer.
Then you pick up that excellent butterflied lamb at Costco, marinate it overnight in a garbage bag (the best marination tool ever made) with olive oil, crushed garlic cloves, white wine, lemon juice, pepper, thyme and rosemary - then throw it on the charcoal, cook it on hot coals - blood-rare in the middle but almost burned on the surface, sliced thin, and have a feast fit for kings.
Got any leftovers? Not likely, but good for the best sandwiches in the world. White bread, salt, pepper, and mayo.
I like grilled lamb best with oven-roasted potatoes, and I will eat regular mashed potatoes or garlic mashed potatoes with anything. Salad first maybe, but no nasty vegetables to detract from the lamb. Perhaps olive-oil-and-garlic marinated grilled vegetables with the lamb if you are one of those people who think eating vegetables enhances life.
By the way, serving white wine with lamb is a crime. Why do people in America ever do it? Lamb is neither an oyster nor a lobster, and it demands a high-octane, heavy bodied beverage.
