Roux vs. Rue: What's the Difference?

Roux is a thickening agent made from equal parts fat and flour cooked together and used in cooking to create rich sauces and gravies. It serves as a base for many dishes, particularly in French and Cajun cuisines. On the other hand, rue can refer to an emotion of regret or sorrow or to a type of herb, Ruta graveolens, commonly used in traditional medicine or flavoring but rarely found in modern cooking. While roux is pronounced like 'roo,' rue as in the herb or emotion is also pronounced 'roo,' which can lead to confusion despite their very different uses.

Roux vs. Rue in a nutshell

While roux and rue share a pronunciation, they represent wholly different concepts. Roux is a culinary cornerstone, a mixture critical for thickening and enhancing flavors in cooking. Rue, however, plays double duty: as a verb, it conveys regret or remorse, and as a noun, it names a once-common herb with a notably bitter taste. It is the context rather than the pronunciation that distinguishes their use: one belongs to the kitchen, and the other to the realms of emotion and herbal lore.
