Brioche. A rich, bready bun made from yeast dough with eggs and butter. Brioches are often cooked in a characteristic fluted mould. Brioche dough is used for breads, cakes and for enclosing other ingredients which may be either sweet or savoury. Italian brioches may be filled with jam (US: jelly) or custard or plain. It also means beaten, whipped up.
