La Cornue Glossary
La Cornue Glossary is a common question among La Cornue owners. This guide walks through it step by step with technician-grade detail.
La Cornue uses French terminology rooted in its heritage and craftsmanship. This glossary defines the key terms you’ll encounter when learning about, buying, or maintaining a La Cornue range.
Oven and cooking terms
- Voûte (vaulted oven) — The signature arched, sealed oven dome that surrounds food with radiant heat. No window on the Château. See our how the vaulted oven works guide.
- Plaque coup de feu (French Top) — A cast-iron simmer plate engraved with stars, providing concentric heat zones from a center boil to an edge hold. See our French Top guide.
- Flamberge — A gas rotisserie module for spit-roasting.
- Teppanyaki — An electric flat-top griddle module.
- Dual-fuel / dual-circuit — A range combining a gas rangetop with an electric oven (or gas + electric vaulted ovens). See our dual-fuel guide.
Brand and craftsmanship terms

Putting the terms to use
Knowing this vocabulary pays off in two practical ways. When you shop, terms like voûte, plaque coup de feu, dual-fuel, and the named finish collections let you compare configurations precisely rather than guessing. When you need service, naming the part — the 06ELTS01 hi-limit thermostat, a flammes burner, a catalytic panel — or the indicator you are seeing — a flashing “U,” an “H,” an E2 or U400 — speeds an accurate diagnosis and the right genuine parts. For decoding model names and SKUs, see our model and SKU guide, and reach our team for any repair needs. Many of these French terms — voûte, plaque coup de feu, flamberge, Compagnons, étoiles — reflect the brand’s heritage and the specific craftsmanship behind features no mass-market range offers.
