A shared kitchen raises a lot of practical questions — so we’ve turned the big ones into their own plain-English answers. Each is written by people who live this, grounded in the guidance below.

Warm, honest answers — not medical advice. For personal medical decisions, talk to your gastroenterologist or your national coeliac society.
