U+1F950 Croissant

The Wikipedia has the following information about this codepoint:

A croissant (UK: , US: ; French: [kʁwasɑ̃] ) is a French pastry made from puff pastry in a crescent shape.

It is a buttery, flaky, viennoiserie pastry inspired by the shape of the Austrian kipferl, but using the French yeast-leavened laminated dough. Croissants are named for their historical crescent shape. The dough is layered with butter, rolled and folded several times in succession, then rolled into a thin sheet, in a technique called laminating. The process results in a layered, flaky texture, similar to a puff pastry.

Crescent-shaped breads have been made since the Renaissance, and crescent-shaped cakes possibly since antiquity. The modern croissant was developed in the early 20th century, when French bakers replaced the brioche dough of the kipferl with a yeast-leavened laminated dough.

In the late 1970s, the development of factory-made, frozen, preformed but unbaked dough made them into a fast food that could be freshly baked by unskilled labor. The croissant bakery, notably the La Croissanterie chain, was a French response to American-style fast food, and as of 2008, 30–40% of the croissants sold in French bakeries and patisseries were baked from frozen dough.

Croissants are a common part of a continental breakfast in many European countries.
