When I realized it was going to be impossible to avoid gluten contamination if I lived with a gluten-eater, we immediately decided to make the whole house gluten-free.
I wish I could say a mixed-gluten kitchen was easier in a sticks-and-bricks home, but our apartment kitchen at the time was a little smaller than our RV’s kitchen, so that’s not true. The fact is, it’s extremely difficult to maintain a mixed kitchen, and impossible for us personally. So in preparation for a very a deep cleaning, we sorted everything in the kitchen to decide what could stay and what must go.
Maybe this post will help you if you find yourself in a similar situation, following a celiac diagnosis or eliminating gluten for other health reasons.
