Why it works: Parsnip and celery match in chemistry and in kitchens. They rank in the top 3% of all ingredient pairs, and 560 recipes mention both. Both carry myristicin, which smells spice, warm. The science ↓
The recipe
Ingredients
Contains: egg, milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the vegetables
Wash and slice the parsnips, Jerusalem artichokes, celery, and onion.

Make the soup
Add enough stock to cover the vegetables and mash them well.
Pass the mixture through a fine sieve into a soup pot.
Stir in the sauce tournee or plain sauce.
Finish and serve
Before serving, mix in the boiled cream and egg yolks, stirring gently to avoid curdling.
Add diced, stewed celery for an extra touch.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Parsnips or white carrots
- Give the soup its body and a mildly sweet flavour as they soften.
- Jerusalem artichokes
- Add bulk and a nutty, earthy flavour while thickening the purée.
- Butter
- Adds richness and carries flavour as the vegetables stew.
- Boiled cream
- Adds richness and a smooth, velvety mouthfeel.
- Egg yolks
- Enrich and thicken the soup, giving it a silky texture when gently heated.
The step that matters
Adding the egg yolks and cream. Egg yolks can scramble and curdle if the soup is too hot or stirred vigorously. Mixing them in gently, off the heat before serving, keeps the soup smooth and creamy.

Fit is the average pairing score against jerusalem artichoke, celery, onion, butter, sauce, cream, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
