Why it works: Beans and tomato match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 2,713 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Clear Soup Stock
Ingredients
Directions
Make the stock
Wash the meat.
Place the meat in cold water without salt.
Bring to a boil slowly, skimming frequently for the first hour.
Add salt.
Simmer the stock for four hours on low heat.
Add a pinch of black pepper.
Strain the stock into a jar.
Let it cool overnight and remove any grease.
Brown and simmer
In a separate pot, brown half of the meat in marrow or drippings.
Add the remaining meat, bone, and fat to the soup kettle.
Let the mixture stand for 15-20 minutes until the water is red.
Bring to a boil.
Add the browned meat.
Cover and simmer slowly for six hours.
Add vegetables one hour before finishing.
Do not add salt until ready to remove from heat.
Strain through a fine sieve.
When cold, remove grease and season with salt and pepper.
Make the bean soup and serve
In another pot, place soaked beans with the beef bone, tomatoes, onion, cloves, and fill with cold water.
Simmer all day.
Mash the beans through a colander and strain the mixture.
Season with Tobasco, Worcestershire sauce, salt, pepper, and sherry.
Serve with a slice of lemon and a sprinkle of finely-chopped hard-boiled egg.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Provides the meat flavour and gelatin-rich body of the stock as it simmers.
- Beef bone
- Releases collagen and minerals during long simmering, adding body and depth to the broth.
- Beans
- Break down when mashed and strained, thickening the bean soup and giving it body.
- Tomatoes
- Add acidity and savoury depth to the bean soup.
- Onion
- Adds aromatic sweetness and savoury flavour as it simmers into the soup.
The step that matters
Skimming during the first hour of boiling. Impurities and proteins rise to the surface as the stock heats. Skimming them early keeps the broth clear and free of a greasy or cloudy look.
