Cordial and liqueur are both sweet, flavored beverages, but they are made differently and have some key differences. Cordial is a non-alcoholic sweet drink made from orange juice, zest, sweetener, and water, it's a concentrated syrup that is usually diluted with water or sparkling water. Liqueur, on the other hand, is an alcoholic beverage made from a combination of distilled spirits, such as brandy or vodka, orange zest, herbs, and spices. It's also sweetened, but the level of sweetness can vary. Both cordials and cordials are typically used in cooking and baking. While liqueurs are often sipped straight or on the rocks, cordials are diluted with water or sparkling water.
