Why it works: Onion and potato are a kitchen classic. They rank in the top 3% of all ingredient pairs, and cooks put them together in 9,023 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ingredients
Directions
The book says “a hot oven”. The 400°F in the steps is the modern equivalent, not the book's own figure.
Make the soup
Boil the beef or veal slowly until tender.
Add the sliced onions, diced potatoes, and cabbage to the boiling broth.
Stir in the butter and lard, and season with salt and pepper.
Boil for one hour.
Cut the beef into small pieces before boiling.
Bake and serve
Place the cooked meat in a baking pan.
Add butter and pepper to the pan.
Bake in a hot oven (400°F/200°C) for five minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Beef or veal
- Provides the main meaty flavor and chewy, substantial texture when cooked tender.
- Onions
- Add sweetness and aroma as they soften in the broth.
- Potatoes
- Release starch that softens the vegetables and slightly thickens the broth.
- Cabbage
- Adds bulk and a mild sweetness as it cooks down in the broth.
- Butter
- Adds fat for richness and a smooth mouthfeel in the soup.
- Lard
- Adds fat that carries flavor and gives the broth a rounder richness.
The step that matters
Boil the beef slowly until tender. Gentle simmering lets the connective tissue in the meat break down slowly, leaving it tender. A hard, rapid boil tightens and toughens the muscle fibers and can leave the meat dry and stringy.
Swap the cabbage
How well each one fits the dish's main ingredients (beef, onion, potato, butter, pepper):
- Chivefits better
- Carrotfits better
- Tomatofits better
- Cabbagethe original
Fit is the average pairing score against beef, onion, potato, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
