Is it hot enough?

[SweetLuci]

 Judging the interior temperature of reheated leftovers such as lasagna or a casserole can be difficult. To avoid serving leftovers that are still too cool in the center, Try this: Poke the center with the blade of a butter knife, leave it for 15 seconds. Remove the knife, and touch the blade to the back of your hand. If the metal is hot, the center of the casserole is fine. If not, heat for a little longer.
