Garlic sauce in various cuisines. Mujdei is a spicy sauce in Romanian cuisine made from garlic cloves crushed and ground into a paste, salted and mixed with water and vegetable oil. Sunflower oil is almost always used. Skordalia is a thick puree (or sauce, dip, spread, etc.) in Greek cuisine made by combining crushed garlic with a bulky base—which may be a purée of potatoes, walnuts, almonds, or liquid-soaked stale bread—and then beating in olive oil to make a smooth emulsion. Vinegar is often added. Ta'leya is a garlic sauce in Egyptian cuisine made by frying garlic and adding vinegar and spices.
Hollandaise sauce in English as early as 1573, though without a recipe showing that it was the same thing. The first documented recipe is from 1651 in La Varenne's "Le Cuisinier François" for ""asparagus with fragrant sauce"": La Varenne is credited with bringing sauces out of the Middle Ages with his publication and may well have invented hollandaise sauce. A more recent name for it is "sauce Isigny", named after Isigny-sur-Mer, which is famous for its butter. Isigny sauce is found in recipe books starting in the 19th century. By the 19th century, sauces had been classified into four categories by Carême.
