Why it works: Carrot and celery match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,173 recipes. Both carry myristicin, which smells spice, warm. The science ↓
Hessian Soup and Ragout
Ingredients
Directions
Prepare the ox-tails
Clean the ox-tails.
Soak the ox-tails in water.
Stew the ox-tails in 5-6 quarts of water until tender.
Let the soup cool.
Remove the fat from the soup for later use.
Make the soup
Add split peas, carrots, turnips, potatoes, onions, sweet herbs, and celery to the soup.
Simmer until the vegetables are tender enough to pulp with the peas through a sieve.
Season with pepper, coarse sea salt, mace, allspice, cloves, and Cayenne pepper.
If the soup is not thick enough, add a slice of bread. Pulp the bread through a colander.
Mix in rice flour gradually.
Make the ragout and finish
For the Ragout, cut the best parts of the head and tongue into small pieces. Rub the pieces with seasoning.
Simmer the pieces in a quart of the reserved soup until tender.
Add mushroom ketchup, walnut ketchup, soy sauce, port wine, and mustard, and boil together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Ox-tails
- Provide rich meat and gelatin that give the stock body and savoury depth.
- Split peas
- Break down during simmering to thicken the soup and give it a smooth texture.
- Potatoes
- Break down when pulped, adding starch that thickens the soup further.
- Onions
- Add sweetness and aromatic flavour as they soften during long simmering.
- Mushroom ketchup
- Adds concentrated savoury umami flavour to the finished soup.
- Port wine
- Adds sweetness, depth and a fruity note to the ragout and soup.
The step that matters
Remove the fat after cooling. Fat from the stewed ox-tails rises and solidifies as the soup cools, so skimming it off gives a lighter, cleaner-tasting soup before the vegetables and thickeners are added.
Swap the mace
How well each one fits the dish's main ingredients (peas, carrot, turnip, potato, onion, celery, pepper):
- Parsleyfits better
- Thymefits better
- Marjoramfits better
- Macethe original
Fit is the average pairing score against peas, carrot, turnip, potato, onion, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
