Flammekueche (tarte flambée)

An Alsatian farmhouse flatbread developed to test a wood-fired bread oven's peak heat: an exceptionally thin, cracker-like dough topped with crème fraîche (or fromage blanc), thinly sliced onions, and lardons, baked very briefly at very high heat. Often marketed and compared to pizza for its shape and hot-oven method, but built on an unleavened or barely leavened dough and a dairy rather than tomato base — several culinary sources classify it as a distinct regional tart/flatbread tradition rather than a pizza.

Disputed: Widely marketed and compared to pizza for its thin, round-or-rectangular, hot-oven-baked form, but many culinary sources treat it as a distinct tart/flatbread tradition rather than a pizza, given its unleavened or barely leavened dough and dairy-based (not tomato-based) topping. Included here as a related flatbread tradition, not asserted as an undisputed pizza style.

• Exceptionally thin, cracker-like, unleavened or barely leavened dough, thinner than any true pizza dough in this catalogue
• Topped with crème fraîche or fromage blanc rather than tomato sauce
• Thinly sliced onions and lardons (bacon) as the standard traditional toppings
• Baked very briefly at very high heat, traditionally in a wood-fired bread oven

Hydration

45-55 percent of flour weight (typically 50 percent of flour weight)

Salt

1.5-2 percent of flour weight (typically 1.8 percent of flour weight)

Oil

2-4 percent of flour weight (typically 3 percent of flour weight)

Mixing: Hand or machine mixed to a firm, low-hydration dough

Kneading: Brief kneading, similar to a pastry or cracker dough

Shaping: Rolled paper-thin with a rolling pin, not hand-stretched

Expected crumb: None in the usual sense — a thin, crisp sheet

Tolerance: A firm, low-hydration dough rolled rather than stretched, closer to a pastry or cracker dough than any leavened pizza dough in this catalogue

• All-purpose flourTraditionalGenerally accepted

  A moderate-protein flour rolled thin gives the exceptionally crisp, cracker-like base this style requires without excess chew.

1. Roll the dough paper-thin into a long rectangle or oval
2. Spread thinly with crème fraîche or fromage blanc
3. Top with thinly sliced onions and lardons
4. Bake very briefly at very high heat

Traditional method: Wood-fired bread oven at peak heat, or a very hot domestic oven

• Rolling pin shapingDefiningGenerally accepted

  Produces the exceptionally thin, cracker-like base that defines this style.

A rich, creamy dairy base and smoky lardons over an exceptionally thin, crisp, cracker-like base — no tomato, no melted cheese layer

Cut into strips or squares and shared, often as a starter

Cut into rectangular strips · Several strips per person, often shared as a starter before a main course

Less suitable: This style traditionally uses crème fraîche rather than the catalogue's white-sauce entry; white-sauce is used here as the closest currently catalogued dairy-base analogue, not a claim that they are identical preparations.

Derived from this style’s own structural ingredient data — see the construction order & topping load guide for why order varies by style.

1. Sauce: White sauce (béchamel-style)
2. Primary topping: Onion, Cooked bacon

• Flammekueche — Alsace's paper-thin cream, onion, and lardon flatbread

  An Alsatian farmhouse flatbread built on an unleavened, paper-thin rolled dough with a crème fraîche base instead of tomato sauce and no cheese at all — the thinnest, fastest-baked, and only dairy-based build in this catalogue.

A very hot domestic oven and a preheated stone or steel reproduce this style's thin, crisp base reasonably well, though few home ovens reach true wood-fired peak heat

• Treating it as a pizza with a white sauce substituted for tomato — the dough itself is a different, largely unleavened style, not just a topping swap

Pissaladière (Nice, France): A separate French flatbread tradition (onion, olive, anchovy on a bread-like base) with a different regional origin and a leavened, bread-like rather than cracker-thin dough.
