Milk and flour barely smell alike, yet cooks put them together in 78,219 recipes: they work on texture and structure more than aroma.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Milk
Forms the creamy liquid base and adds richness to the bisque.
Condensed tomato soup
Supplies the tomato flavor and color of the bisque.
Flour
Thickens the liquid as its starch heats, giving the bisque more body.

The step that matters

Stir in the flour. Flour clumps when it hits hot liquid unless it is well dispersed. Stirring it in evenly lets the starch thicken the soup smoothly as it heats.

Swap the tomato

How well each one fits the dish's main ingredients (milk, flour):

  1. Arrowrootfits better
  2. Potatofits better
  3. Sweet potatofits better
  4. Tomatothe original

Fit is the average pairing score against milk, flour. Candidates are from the same food group and used in at least 100 recipes.
