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 ↓
Clear Gravy Soup
Ingredients
Directions
Prepare the pot
In a large stew-pan or stock-pot, layer the ham slices at the bottom with the beef and veal.
Break the bones and add them to the pot.
Add the onions, turnips, carrots, celery, cloves, and mace.
Cover the pot and heat over medium-high until the meat sticks to the bottom.
Once browned, cover the meat with hot water.
Simmer and skim
When it approaches a boil, add ½ pint of cold water and skim off the scum.
Repeat adding ½ pint of cold water and skimming until no more scum rises.
Reduce heat and simmer gently for about 4 hours.
Strain and clarify
Strain the broth through a clean cloth into a stone pan without squeezing.
Let it cool, then remove the fat from the top.
Carefully decant the broth, avoiding the sediment at the bottom.
Beat 2 egg whites and their shells.
Add the mixture to the soup and bring to a boil.
Let it settle for 10 minutes.
Strain again through a fine cloth.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg whites (in the method)
- Coagulate as they cook, trapping suspended particles so the broth comes out clear.
- Beef
- Releases gelatin and savory flavor into the broth during long simmering.
- Bones
- Release collagen and minerals that give the broth body and richness.
- Onions
- Add sweetness and aromatic depth to the broth as they simmer.
- Carrots
- Add natural sweetness and mild aroma to the broth.
The step that matters
Skimming the scum. Scum is coagulated protein and impurities that rise as the liquid heats. Removing it as it forms keeps the broth clean and clear rather than cloudy or bitter.
Swap the turnip
How well each one fits the dish's main ingredients (ham, beef, veal, meat, onion, carrot, celery):

Fit is the average pairing score against ham, beef, veal, meat, onion, carrot, celery. Candidates are from the same food group and used in at least 100 recipes.
