Why it works: Celery and carrot 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 ↓
Scotch Barley Soup
Ingredients
Directions
The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.
Make the broth
Cover the meat with cold water in a two-gallon pot.
Bring to a boil, skim the surface, and add the Scotch barley and onions.
Simmer gently for 2 hours or cook in a covered stone pot in the oven at 300°F (150°C).
Skim off the fat, then add celery, turnips, carrots, and button onions.
Cook until the meat is tender but not falling apart.
Remove the meat and keep it warm.
Make the sauce
Strain a quart of broth and thicken it with flour and butter over heat.
Add port wine or catsup for flavor, and pour over the meat.
For veal, mix broth and new milk, thicken with flour and butter, and season with salt, nutmeg, and lemon juice.
Stir in beaten egg yolks and cream near the fire without boiling.
Serve
Serve the sauce over the meat and the broth in a tureen.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Gives the soup its rich beefy or veal flavor and tender body as it simmers.
- Scotch barley
- Swells during simmering, thickening the broth and giving it a chewy texture.
- Flour
- Thickens the strained broth into a smooth sauce when cooked with butter.
- Egg yolks
- Enrich and thicken the sauce gently, adding richness and body when heated without boiling.
- Cream
- Adds richness and smoothness to the sauce, softening its flavor.
The step that matters
Stir in egg yolks and cream without boiling. Egg yolks thicken by gentle heat; if the sauce boils, the proteins scramble and curdle, leaving a grainy, separated sauce.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, barley, celery, turnip, carrot, flour, butter):
- Leekfits better
- Parsnipfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against meat, barley, celery, turnip, carrot, flour, butter. Candidates are from the same food group and used in at least 100 recipes.
