I needed new cookie sheets and I had a Nordic Ware cake pan which I had only just used recently. I was struck by the fact that they have some weight to them. Just used these baking sheets today and they are wonderful. Since they are shiny aluminum, used parchment paper and was very careful with a metal spatula because they will scratch. And you know what the best part is THEY ARE MADE IN THE USA by a family owned business. Can’t say enough good things about them!
