Is fish and chips gluten-free? Not usually, unless the shop has a gluten-free fryer

Not usually. The batter is made with wheat flour, and the chips are often fried in the same oil as the battered fish, so both pick up gluten.

Gluten-free fish and chips

Some chip shops make gluten-free batter and fry it in a separate fryer, either every day or on set days. That’s what makes the difference: gluten-free batter in shared oil isn’t enough.

What to ask

• Is the gluten-free fish cooked in a separate fryer with its own oil?
• Are the chips fried in oil that has never had battered food in it?
• Are the scoops, trays and wrapping kept apart?

Curry sauce and gravy are often thickened with wheat flour, and some mushy pea mixes contain it too; ask about each separately.
