Helvetica mustard sauce by La Pasiva

All Uruguayans have to agree that the most delicious mustard sauce belongs to “La Pasiva”, a fast food chain typical of Uruguay. It is a type of liquid mustard, clear and of particular flavor, slightly spicy and soft.

Although it has an uncertain origin, it is known that it exists at least since 1962, where it was made in the La Pasiva store located in the Recova of the Plaza Independencia in Montevideo.

The original recipe is kept secret, however it is known that it is a mustard with beer-based vinegar, thickened with flour and starch and seasoned with Colman’s Mustard, salt and pepper. The beer used for the base must be of the Plisen brand.
