Why it works: Pepper and marjoram match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and cooks put them together in 2,609 recipes. Both carry estragole, which smells anise, licorice. The science ↓
Calves' Head Soup
Ingredients
Directions
Prepare the head
Soak the calves' head in water, then in salt water, and boil.
Remove the brains and tie them in a bag to boil.
Make the soup
Strain the broth and cut all meat and brains into small dice.
Add diced potatoes and small dumplings made from flour, water, and lard.
Season with red pepper, pot herbs, and sweet marjoram.
Chop the hard-boiled eggs finely and add to the mixture.
For meatballs, mix chopped meat with salt, pepper, and flour, then fry in butter.
Serve the soup with sherry to taste.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calves' head
- Provides the meat and brains that give the soup its body and rich flavour.
- Potatoes
- Soften during simmering and thicken the broth as they break down slightly.
- Flour
- Binds the meatballs and thickens the dumplings so they hold their shape.
- Hard-boiled eggs
- Add richness and a firm, mild texture to the finished soup.
- Lard
- Adds fat and richness to the dumplings, making them tender.
The step that matters
Boiling the calves' head. Soaking draws out blood and impurities, and gentle simmering keeps the meat tender and the broth clear. A hard rolling boil can toughen the meat and cloud the broth.
Swap the marjoram
How well each one fits the dish's main ingredients (potato, flour, pepper, egg, meat, butter, sherry):
- Parsleyfits better
- Thymefits better
- Nutmegfits better
- Marjoramthe original
Fit is the average pairing score against potato, flour, pepper, egg, meat, butter, sherry. Candidates are from the same food group and used in at least 100 recipes.
