What's that supposed to mean?
You can set two alum pans in a large pan or on a baking sheet. You always need something under an alum pan if it's going to be heavy so it can be lifted in and out of the oven without bending.
If you're reheating in the oven and don't want foods touching, you can use alum foil to create individual pockets in the same pan.
Do let us know how it turned out. Did you use similar seasonings for both?
