Jay, based on my extremely limited experience if you do try lamb try to get some from a younger, smaller animal as the meat will have a milder flavor. One of the suppliers around here has a 10 month/150 pound rule .
Great looking lamb chops, Askanison!
SC - That's if you like it mild (I don't always). Here's another tip for finding the mildest lamb: look for spring lamb. Outside the US that's a common term for the youngest, most tender and mildest lamb and it's usually 3-5 months old. It's expensive but it's great stuff.
"Lamb" in a lot of countries outside the US refers to sheep that's 12 months old or less. However, from what I've seen, in the US it can mean sheep of any age, and that means you could actually be buying mutton.
Since I happen to like grilled mutton, I look for it. And I look for it specifically because I don't want to pay the higher price for mutton disguised as lamb.
