Chocolate syrup is a chocolate-flavored condiment. It is often used as a topping for various desserts, such as ice cream, or mixed with milk to make chocolate milk. Chocolate syrup is also used to top puddings.
A simple chocolate syrup can be made from unsweetened cocoa powder, sugar and water. Recipes may also include other ingredients, such as corn syrup, malt, and flavorings like vanilla extract.
Chocolate syrup was often used in black-and-white movies to simulate blood, because it was safe for the performers to swallow, easy to get out of clothing, and cheap to buy. It was used in many movies, including The Wasp Woman and Psycho.
