Is it important to have separate cooking utensils and pots in the kitchen for gluten eaters and non-gluten eaters?
The key to avoiding cross contamination in the kitchen is to be mindful of any utensils and surfaces where gluten-containing particles may get stuck or are difficult to clean. It is recommended to have a separate gluten-free colander for pasta, sifter for flour, and toaster for bread products. You may use the same toaster oven for both gluten-containing and gluten-free foods by placing a clean piece of aluminum foil down each time you toast a gluten-free product. Mixing spoons and cutting boards should be made of a non-porous material such as plastic or glass. These utensils along with pots, pans, and plates may be used for both gluten-containing and gluten-free products if they are washed thoroughly between uses.
