Cream soups are typically thickened with which combination?

• A. A roux and dairy
• B. Only vegetables
• C. Gelatin
• D. Water and salt

Answer: (C)

Cream soups get their body mainly from a roux combined with dairy. A roux—fat cooked with flour—develops starch that swells as liquid is added, giving the smooth, velvety thickness that characterizes these soups. Finishing with dairy (milk or cream) adds richness and helps maintain that creamy texture without relying on starchy strength alone.

Gelatin is used to set gels or to add body in some cold preparations, but it isn’t stable or appropriate for hot cream soups. It can break down with heat and dairy, producing a texture that isn’t the smooth creaminess these soups require. Water and salt don’t thickening the soup; they only season and hydrate, and they don’t provide the structure needed. Relying on vegetables alone can contribute some body if puréed, but the classic, reliable method for true cream-soup thickness is a roux with dairy.
