The pastries known as bizcochos are Germanic in origin: croissants, known as medialunas, are the most popular of these, and can be found in two varieties: butter- and lard-based. Also German in origin are the Berlinese known as bolas de fraile ("friar's balls"), and the rolls called piononos. The facturas were re-christened with local names given the difficult German phonology, and usually Uruguayanized by the addition of a dulce de leche filling.
