Flambe is an adjective that means served with flaming liquor.
Coming directly from the French word for flame, flambe has been used by English speakers since the late 19th century. In addition to being an adjective that describes the way a particular food is cooked, it can also be used as a verb to describe the actual cooking. Here’s an example of the verb version:
Having always been a fan of French cooking, I thought it would be a good idea to flambe something I served for dinner. In retrospect, I probably should have chosen something besides a plate of pancakes to set on fire.
