EVIDENCE-BASED ANSWER
Where Does Gluten Hide in Sauces?
Gluten can enter sauces through regular soy sauce, wheat-based roux, malt vinegar, beer, some stocks, seasoning blends, and shared utensils. Never judge by color or thickness. Read the full label or ask for the recipe, then check how the sauce is prepared. A naturally gluten-free sauce can still be contaminated in a shared pan or ladle.
