Roasting
Lamb
Place
lamb, fat side up (if present), on a rack in an open, shallow roasting
pan.
A meat thermometer is the best guide for checking doneness. It
measures the internal temperature of the cooked lamb. Insert the
meat thermometer into the center of the thickest muscle of the meat,
being careful not to let the thermometer touch any fat or bone,
or the bottom of the pan.
Roast lamb to desired doneness (145 to 150º F. for medium-rare
and 160º F for medium). Push the thermometer into the meat
a little farther. If the temperature drops, continue cooking. If
the temperature stays the same, remove the roast from the oven.
To make slicing easier, allow larger roasts to stand for 15 to
20 minutes after removing from oven. Cover the meat with foil to
help keep it warm. The meat will continue to cook slightly during
standing, so remove the roast from the oven at a slightly lower
degree of doneness than you prefer. Roast 325º F. until meat
thermometer registers 5º below desired doneness. Allow smaller
roasts to stand for 5 to 10 minutes after removing from the oven.
Do not add water or liquid, and do not cover.

Convection Roasting Lamb
Roasting in a convection oven takes place as hot air circulates
around all the surfaces of the food. Because most Lamb cuts are
naturally tender, lamb works well in convection cooking. The wide
variety of convection ovens (or microwave ovens) available makes
it difficult to create a timetable. The American Lamb Council suggests
following the manufacturer's instructions.
