Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal knuckle or scrag
- Releases gelatin during long simmering, which sets the cooled liquid into a jelly.
- Flour
- Thickens the jelly as it heats, giving it body.
- Butter
- Adds richness and a smooth mouthfeel to the finished jelly.
- Mace
- Adds warm, aromatic spice flavor to the jelly.
The step that matters
Skimming during the simmer. Fat and foam rise to the surface during the long simmer. Skimming them keeps the liquid clear and clean-tasting, so the cooled jelly is not greasy or cloudy.
Swap the mace
How well each one fits the dish's main ingredients (veal, pepper, butter, flour):
- Parsleyfits better
- Sagefits better
- Turmericfits better
- Macethe original
Fit is the average pairing score against veal, pepper, butter, flour. Candidates are from the same food group and used in at least 100 recipes.
