Have to say that lamb is a gigantic component of the average Aussie diet. A lot of lamb is hogget though. Generally here, lamb legs are roasted and chops are grilled, bbq-ed or pan fried. Frenched lamb cutlets retail here for about A$33/kg. I bought a 2.4kg leg of mutton on the weekend for A$10.87 reduced from A$18.xx. Took me four hours to roast but it was yummy!
Good lamb you don't have to do anything with, although my preferred method of roasted leg is drizzle it with olive oil (but only a little), rub it with salt and pepper, lots of garlic, baby onions and potatoes in the pan, and pour balsamic vinegar over it. If I can be bothered, sometimes I add some honey to it as well. Must have pumpkin in there then too.
[Roasting times: Lamb leg 40mins per pound/350F oven; mutton is 45mins/350F oven]
If I am pan-frying or grilling, I would coat chops with a souvlaki seasoning mix (or garlic, parsley, salt and pepper). Lamb really responds well to salt being added to the pan not long before serving but not when you first put it in the pan.
Haven't tried anyone else's lamb other than a leg of lamb in Germany when I was 18, so I really couldn't say what it was like - other than very small for the price and for what we were/are used to here.
Lamb mince comes down very cheap here - as low as A$4.99/kg. It is great in moussaka or to make lamb burger patties instead of the usual beef ones. Chunks of roasted season meat in a souvlaki is hard to beat as well.
Lamb is my all time favourite red meat. I seldom ever buy beef, other than mince. Although after having only just finished eating the leg of mutton (all week I might add!), beef could make a nice change!! Duck would be better though!! LOL
