Care for baker's half sheet and What does Ina use?

  • 5

I bought a Nordic Ware baker's sheet and I wonder if there is any way to keep the sheets from turning dark? I also wonder which sheet's Ina uses because her always look nice and silvery.

  1. A pretty safe bet is that if something looks new on tv, it is new. The use of cooking sprays is a big culprit of discoloration. Parchment paper, Silpat type liners and aluminum foil all can help reduce discoloration. Hand washing will reduce discoloration whereas cleaning in a dishwasher will promote discoloration. Any oil, grease or fat residue has the ability to act like seasoning. The longer you allow it to build up the harder it will be to remove.

    1. Hand wash them. Don't put them in the dishwasher. Don't make anything acidic on them. I recently used one as a water bath, in which I baked an egg dish in a pyrex baking dish--don't do that either! Something in my hard water reacted with the aluminum and turned it dark in the spots where the pyrex was not. Over time the dark spots are diminishing, but still, they're there.

      1. Are you talking about something burning on, or a slight darkening of the aluminum where something sat on it? If it's the latter, the best thing is to learn to live with it. Barkeeper's Friend may help with burned on brown, but I've learned to live with that, too. I usually just use the least browned of my four half-sheet pans.

        1. It's the cooking spray and then putting the pan in the dishwasher that is the culprit combined with the pan with the residue then being sprayed again, put in the oven and the the dishwasher. I gave a couple of commercial grade aluminum sheet pans to a relative with young children and a kitchen with two ovens. I figured she could really vet the cookie baking done in no time. Well, she though she would save time by not washing the pans but doing as I just described. She later backed cookies on aluminum foil on those same pans. I bet it tajes all of three minutes to wash a sheet pan after use. Later stuggles with a crappy pan waste more time. This is the same person who told me she did not have time to organize her kitchen drawers (big kitchen). As opposed to hunting throughout the kitchen looking for a specific tool?

          1. Believe me, she gets new pans for every episodes. Go into any professional kitchen and their pans looked well used. Don't worry so much about how they look.
