Why it works: Clove and cinnamon match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,189 recipes. Both carry ethyl cinnamate, which smells sweet, balsamic. The science ↓
Mock-turtle Soup
Ingredients
Directions
Make the soup base
Boil the meat until tender, then remove and cut into small pieces.
Return the meat to the pot and season with mace, cloves, cinnamon, peppercorns, and chopped onion.
Grind the spices before adding them.
Brown the flour in a pan to thicken the soup.
Finish and serve
Burn the sugar until caramelized, then add it to the soup along with the egg yolks and tomato ketchup.
Boil all ingredients until fully cooked.
Just before serving, stir in the claret or other wine.

Cinnamon and sugar barely smell alike, yet cooks put them together in 30,779 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Browned flour thickens the soup and adds a toasty, nutty flavour.
- Egg yolks
- Rubbed-fine yolks enrich the soup and help give it a smooth, thick body.
- Sugar
- Caramelized sugar adds sweetness and a deep, slightly bitter colour.
- Tomato ketchup
- Adds acidity, sweetness and savoury depth to the soup.
- Claret or other wine
- Adds acidity and aromatic depth when stirred in at the end.
The step that matters
Browning the flour. Flour browned slowly in a dry pan toasts evenly and thickens well. If it scorches, it turns bitter and can spoil the soup's flavour, so it needs steady heat and constant stirring.
Swap the onion
How well each one fits the dish's main ingredients (meat, mace, clove, cinnamon, flour, sugar, egg):
- Arrowrootfits better
- Shallotfits better
- Sweet potatofits better
- Onionthe original
Fit is the average pairing score against meat, mace, clove, cinnamon, flour, sugar, egg. Candidates are from the same food group and used in at least 100 recipes.
