This bakeware from Oneida really stands the test of time. I've had my Oneida cookie sheets and bread pans for ages. I'm pretty sure the cookie sheets were pilfered from my mom's collection at one time or another. They work really well. They're the largest cookie sheets I own so they get used for all kids of things. I don't actually bake cookies all that often anymore. With all the peanut allergies in school, home baked goods aren't allowed in my kids classrooms so I don't end up making them very often anymore. I still use the large cookie sheets for cooking ribs in the oven pretty often though. A little vegetable oil and some of my spice rub, is all the ribs need. I toss them on the cookie sheet, prep them there and cook them in the oven for a couple hours on low. I line the cookie sheet in tin foil to make clean up easier, but these sheets are nice enough that they come clean fairly easily anyways.
