The drained pickled cherries can be refrigerated overnight.
If you can find it, try using milk-fed lamb that's about eight weeks old. The legs will be very small (a few pounds), but do several and cook them for a little less time. If you are using spring lamb, don't go for anything older than three-to-five months, born in late winter or early spring. These should weigh about 4 pounds with the aitch bone and shank off.
