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

What each ingredient does

Veal
Gives body and savoury meaty flavour to the sauce as it cooks in the butter.
Butter
Carries the aromatics and adds richness and fat to the sauce.
Flour
Thickens the liquid into a smooth, lightly bodied sauce.
Cream
Adds richness and a smooth, velvety texture to the finished sauce.
Broth
Supplies the liquid base and savoury flavour of the sauce.

The step that matters

Stir continuously for 30 minutes. Flour thickens as it heats in liquid and can scorch or form lumps if left unattended. Constant stirring keeps the sauce smooth and evenly cooked while it thickens.

Flavor stand-ins for the mace

  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).
