Are marshmallows gluten-free? Usually, the extras are the risk
Usually, yes. Most marshmallows are made from sugar, glucose syrup, gelatine (or a plant gelling agent) and a dusting of corn or potato starch.
What to check
- The dusting and the starch: most use corn or potato starch, but wheat starch is possible. In the EU and UK wheat is named and highlighted on the label.
- Glucose syrup made from wheat is so refined that the EU exempts it from allergen labelling; it is gluten-free.
- Coated, filled and flavoured marshmallows: biscuit coatings, cereal pieces and cookie fillings contain wheat.
- S’mores and campfire treats: the marshmallow is usually fine, the graham cracker or biscuit isn’t. Use a gluten-free biscuit.
