  2. Mix the flour smoothly with the cold water in the saucepan.

  3. Let the mixture sit for an hour before heating.

Heat and finish

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: isobutyraldehyde (malty, green).

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.

What each ingredient does

Flour
Thickens the liquid as its starch swells when heated.
Butter
Adds fat and rich flavor to the finished sauce.

The step that matters

Stir continuously while heating. Flour particles can clump and scorch on the base of the pan if the mixture is not kept moving, so constant stirring keeps it smooth and evenly heated.
