As promised last week we'll talk about rimmed sheet pan accessories! Should you register for two Norpro 18"x12" Commercial Grade Aluminum Jelly Roll Pans it would be a great idea to register for items that would work in harmony with your rimmed sheet pans.
First, I'd recommend getting wire cooling racks that fit inside the sheet pans. ATK recommends a grid-style rack with tightly woven, heavy gauge bars, and that is dishwasher safe. Register one per sheet pan. These cooling racks will be useful to cool baked goods, of course. However, these will also be useful roasting and for draining grease.
Second, if you bake a lot I'd recommend getting Silpat liners for your rimmed sheet pans. Again, one per sheet registered for. These nonstick liners will allow you to bake without greasing the sheet pan and you'll never have to wonder if you have parchment paper at home. Some bakers still prefer to cook/bake with parchment paper but I find that having the Silpat liners is a good reusable resource that's earth-friendly.
