French Food Allergy Guide
Cuisine française · France
French cuisine heavily relies on butter, cream, and flour as structural elements rather than optional garnishes. The technique of 'monter au beurre' (swirling cold butter into sauces off-heat) and the use of flour-based roux to thicken stews make dairy and gluten pervasive, hidden hazards even in savory meat or vegetable dishes.

butter
beurre
Used to finish almost all pan sauces (monter au beurre) and sauteed vegetables at the last second, even if dairy is not listed as a menu ingredient.
roux
roux
A cooked mixture of equal parts flour and butter used as the thickening base for three of the five mother sauces (Béchamel, Velouté, Espagnole) and countless stews.
anchovies
anchois
Melted into olive oil bases for regional specialties like tapenade and pissaladière, or blended into dressings without being visibly identifiable.
almond flour
poudre d'amandes
The structural base for classic pastries like macarons, financiers, and frangipane fillings, posing a severe risk for those expecting wheat-based baked goods.
egg yolk liaison
liaison
A mixture of egg yolks and cream whisked into white stews (like Blanquette de Veau) at the very end of cooking to enrich and thicken the sauce.
lupin flour
farine de lupin
Commonly used in French bakeries as a wheat substitute in gluten-free breads and pastries. Lupin is a legume with high cross-reactivity for individuals with severe peanut allergies.
