Why it works: Celery and pepper match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 16,012 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
Dripping Soup
Ingredients
Directions
Prepare the base
Wash the barley.
Boil the barley in 6 quarts of water over low heat. Skim the surface.
Reduce the liquid to about 5 quarts.
Add the vegetables and thicken
Add the celery (or celery seed) and onion.
Boil for another hour until reduced to 1 gallon.
In a bowl, mix the oatmeal with the drippings. Gradually add this mixture to the soup.
Season and finish
Stir in the soup-herb powder, black pepper, and salt. Let it boil for a few minutes until well combined.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Barley
- Softens as it simmers, releasing starch that gives the soup body and substance.
- Oatmeal
- Adds starch that thickens the broth and gives it a heartier, creamier texture.
- Drippings
- Supply fat that carries flavour and adds richness and a savoury depth to the soup.
- Onion
- Releases sugars and aromatic compounds as it cooks, adding sweetness and savoury background flavour.
- Celery
- Contributes aromatic compounds that add a fresh, vegetal background flavour to the broth.
The step that matters
Adding the oatmeal and drippings mixture. Adding the oatmeal mixture all at once can clump it into lumps. Mixing it with fat first and adding it gradually lets the starch disperse evenly so the soup thickens smoothly.
Swap the onion
How well each one fits the dish's main ingredients (barley, celery, pepper):

Fit is the average pairing score against barley, celery, pepper. Candidates are from the same food group and used in at least 100 recipes.
