I would like to replace my muffin pans and loaf/bread pans. I have darkly-colored bread pans which seem to burn the top of my banana bread consistantly! I have one loaf pan, very old, that is made from aluminum which is great. Are these pans still available? My muffin pan is an inexpensive brand. Any recommendations on quality pans? Is restaurant quality bakeware expensive and worth the price? I would like to know the brand and the material the pans are made from would be appreciated. Thanks a bunch!
