What is the French mother sauce made from veal stock and tomato purée? Espagnole is the answer.
Espagnole is one of the classic French mother sauces. Its traditional preparation combines brown stock, often made from veal or beef, with a dark brown roux and tomatoes or tomato paste. Mirepoix, herbs, and sometimes bacon or ham add further depth. The sauce is simmered and reduced to develop its dark color and strong flavor.
The sauce appears in the work of French culinary writers including Vincent La Chapelle and Marie-Antoine Carême. Auguste Escoffier later included espagnole among the five mother sauces that shaped modern French culinary education. Its name means “Spanish” in French, although the sauce is part of the French classical tradition.
Espagnole is also important because it forms the foundation for demi-glace, a concentrated brown sauce made by reducing espagnole with brown stock. It is easy to confuse with velouté, which uses a lighter stock and roux, or béchamel, which is milk-based. Hollandaise is an emulsion of butter and egg yolks, not a brown-stock sauce.
