Featured here is an advertisement for Palmin margarine in a Jewish cockbook from 1909. Palmin was developed by the German chemist Dr. Heinrich Schlinck (1840-1909) at the end of the 19th century as a substitute for animal-based cooking fats. The name Palmin denotes the origin of the product from coconut, that is palm tree. Since margarine was manufactured from vegetable fat, it could be used in cooking both meat and dairy dishes. Before the Great War Palmin, along side another margarine that was manufactured by the firm H. Schlinck & Cie. by the name of Palmona, was marketed as a Kosher brand allowing the Jewish kitchen to broaden its range of tastes by using new recipes previously prohibited by the laws of kashrut. Palmin was not the only kosher vegetable butter at that time. Another well-known kosher margarine was "Tomor," which was produced by Van den Bergh, a Dutch food corporation, at their German branch in the Kleve. Van den Bergh's founder the Dutch industrialist, Simon Van den Bergh (1819-1907), was an observant Jew. Both Palmin and Tomor are brand names that are still used today.
