Roux
Mixture of thickening agent and fat for thickening

Roux is a mixture of flour and fat cooked together and used to thicken sauces. Roux is typically made from equal parts of flour and fat by weight. The flour is added to the melted fat or oil on the stove top, blended until smooth, and cooked to the desired level of brownness. A roux can be white, blond (darker), or brown. Butter, bacon drippings, or lard are commonly used fats. Roux is used as a thickening agent for gravy, sauces, soups, and stews. It provides the base for a dish, and other ingredients are added after the roux is complete.
This brief starts where responsible research should: with the source description of “Roux” as mixture of thickening agent and fat for thickening. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as mixture of thickening agent and fat for thickening. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jun 29, 2026.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
