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

What each ingredient does

Pickled tongue
Forms the main body of the dish, cooked until tender by long boiling.
Tomatoes
Supply acidity and body, and reducing them concentrates their flavor into the sauce.
Butter
Adds fat and richness, giving the sauce a smoother mouthfeel.
Flour
Thickens the sauce when mixed with butter and stirred into the hot tomatoes.

The step that matters

Boiling the tomatoes until reduced by half. Reducing concentrates flavor and evaporates water, so the sauce thickens. Stopping too early leaves it thin and watery, while over-reducing can make it overly sharp and dense.

Swap the tomato

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

  1. Shallotfits better
  2. Leekfits better
  3. Arrowrootfits better
  4. Tomatothe original

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