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 ↓
Crecy Soup
Ingredients
Directions
Make the carrot soup
Scrape and wash the carrots.
Grate the red part of the carrots only and place it in a pan with the butter and sugar.
Steam gently for 45 minutes without browning.
Add the stock, onion, and celery (washed and cut into 1-inch lengths).
Boil for 1 hour and season to taste.
Rub the mixture through a sieve, reheat, skim, and serve.
Prepare the rich soup
Wash and clean all the vegetables and cut them small.
Heat the butter in a pan, add the vegetables, herbs, and lemon rind, and fry for 10 minutes without browning.
Soak the head in salt and water for 1 hour, then place it on top of the vegetables.
Add stock or water, bring to a boil, remove scum, and simmer for 4 hours.
Remove the head, strain the soup, and let it cool overnight.
Clarify and finish
The next day, remove the fat from the soup and place it in a pan.
Beat the egg whites to a froth and add to the soup.
Heat until boiling and scum rises, let it sit for 10 minutes, then strain through a clean cloth.
Reheat the strained soup, add sherry, force-meat balls, and the best part of the head cut into small pieces.
Pour into a tureen and serve.
Make the garnish
For the garnish, remove the yolks from the hard-boiled eggs and place them in a bowl with chopped parsley, cayenne, raw egg yolk, and a little salt.
Pound to a paste, form into nutmeg-sized balls, and simmer in boiling water for 2 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide the main body, sweetness and colour of the soup.
- Butter
- Adds fat for richness and carries flavour when the vegetables are gently cooked.
- Stock
- Supplies the liquid that extracts flavour and gives the soup its moisture.
- Onion
- Adds savoury depth as it softens and releases its flavour into the stock.
- Celery
- Contributes aromatic flavour that rounds out the soup's base.
- Egg yolk
- Binds the garnish paste so the balls hold their shape when simmered.
The step that matters
Clarifying with beaten egg whites. As the whites heat, they coagulate and trap suspended particles and scum. Straining through cloth then removes them, giving a clear soup. Heating too gently or stirring too hard breaks up the trapped solids and leaves the soup cloudy.
