Why it works: Carrot and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 8,053 recipes. Both carry 2,4-decadienal, which smells seaweed. The science ↓
Egg Soup
Ingredients
Directions
Prepare
Cut the ham, veal, onion, and carrot into pieces.
Combine the meat, onion, carrot, parsley, and water in a pot and bring to a slow boil.
Make the broth
Maintain the boil for 3.5 hours, ensuring the water reduces by no more than one-third.
Strain the broth, cool it, and skim off the fat.
Return the broth to the pot, adding the grated turnip and mashed potato.
Season to taste and simmer for 30 minutes.
Serve
Pour the soup into a tureen and top with poached eggs, one for each person.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean ham
- Gives the broth its meaty flavour and body as it simmers for hours.
- Lean veal
- Releases gelatin and savoury flavour into the broth during the long simmer.
- Eggs
- Set when poached, providing a soft, tender protein garnish for each bowl.
- Potato
- Mashed into the broth, it thickens the soup slightly and adds body.
- Turnip
- Adds mild, slightly sweet earthy flavour to the broth.
The step that matters
Maintain the slow boil for 3.5 hours. A gentle, steady simmer extracts flavour and gelatin from the meat while keeping the broth clear. A hard boil emulsifies fat into the liquid and clouds it, and letting the water reduce too much concentrates it unevenly.
Swap the onion
How well each one fits the dish's main ingredients (ham, veal, carrot, turnip, potato, parsley, egg):
