Tarte Flambée

Originated as flammkueche among Alsatian farmers as a bread-oven test bake — when the wood oven was hot enough to bake bread, the baker stretched a scrap of dough thin and threw it in for 90 seconds to gauge the heat. The dough became lunch, with whatever was on hand on top. The format moved from farmhouse to Alsatian winstubs (wine taverns) in the 19th century and to urban restaurants in the wider 'pizza craze' of the 1960s, reaching Paris and beyond.

Originally an Alsatian farmer's oven-test bake — a scrap of dough thrown into the wood oven for 90 seconds at 300°C+ to gauge bread-baking heat. The fromage blanc is structural: lower fat than crème fraîche, won't break.

A paper-thin rectangle of bread dough, no rising agent, blasted in a wood oven for two minutes. Topped with fromage blanc thinned with cream, raw onion in slivers, and lardons. Edges char black, center stays pliable. Eaten with the hands, often folded. The closest French analog to Naples pizza, and the wood smoke on the lardon is the marker — gas-oven versions never read right.

Heat is the whole technique — 300°C+ for 90 seconds. At lower temperatures the thin dough dries to cracker rather than the soft-crisp contrast that defines a real flammkueche. The fromage blanc is structural too: it's lower-fat than crème fraîche so it won't break under wood-oven heat, and its slight tang is what plays against the raw onion. Substituting sour cream gives a heavier, sourer top that cooks past pliable.
