Why it works: Marjoram and thyme match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,225 recipes. Both carry terpineol, which smells pine, woody. The science ↓
Mock Turtle Soup
Ingredients
Directions
Prepare the head
Scald the calf's head.
Cut it into 1-inch squares.
Wash and clean well.
Dry with a cloth.
Stew the soup
Place the pieces in a stewpan with 2 gallons of stock, sweet basil, marjoram, savory, thyme, and parsley.
Add ground cloves, mace, and Madeira or sherry.
Stew gently for 4 hours.
Thicken and finish
In a separate pan, heat the milk and mix in the flour until smooth.
Stir in the egg yolks and heat until near boiling.
Gradually add the milk mixture to the soup while stirring to prevent curdling.
Let it stew together for another 30 minutes.
Before serving, add the forcemeat balls and chopped hard-boiled egg yolks.
Off the heat, squeeze in the lemon juice.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Calf's head
- Provides gelatin-rich meat and connective tissue that give the soup body after long stewing.
- Flour
- Thickens the milk mixture so it can lightly body the soup.
- Egg yolks
- Enrich and thicken the milk mixture, adding richness and smoothness to the soup.
- Madeira or sherry
- Adds sweetness and aromatic depth to the stewed broth.
- Lemon juice
- Adds acidity that brightens the rich, heavy soup.
The step that matters
Gradually add the milk mixture to the soup while stirring. Egg yolks and milk curdle if they meet hot liquid too quickly. Adding the mixture slowly while stirring tempers it, keeping the soup smooth instead of grainy.
Swap the mace
How well each one fits the dish's main ingredients (basil, marjoram, thyme, parsley, clove, sherry, milk):
