Making a good jus de veau -the mother of all brown sauces- takes time and effort. Reason enough for chefs Joost and Paul to develop a jus de veau that helps (home) cooks cook even more delicious meals in no time. After extensive experimentation, the passionate Amsterdammers succeeded in creating the perfect gravy; beautifully clear in color and full of character. The gravy is also available in a game version.
