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

What each ingredient does

Flour
Thickens the liquid into a smooth, coating sauce as it cooks.
Butter
Carries flavour and adds richness while the meats and aromatics fry.
Cream
Adds richness and body, giving the sauce a smoother mouthfeel.
Broth
Forms the savoury liquid base that the sauce is built on.
Bacon or ham
Contributes savoury, smoky flavour to the stock of the sauce.

The step that matters

Stirring while the sauce boils. Flour-thickened sauces can scorch on the bottom or form lumps if left unstirred. Constant stirring keeps the starch dispersed and heat even, so the sauce thickens smoothly.

Flavor stand-ins for the mace

How well each one fits the dish's main ingredients (veal, ham, butter, onion, mushroom, thyme, flour):

  1. Marjorambetter flavor fit
  2. Parsleybetter flavor fit
  3. Garlicbetter flavor fit
  4. Macethe original

Fit is the average pairing score against veal, ham, butter, onion, mushroom, thyme, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
