Why it works: Onion and beef are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 17,092 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Lobster Soup
Ingredients
Directions
Make the base
In a stew-pan, combine the onions, beef, ham, and butter.
Cook until the onions are soft.
Mix in the rich stock, then boil, skim, and strain through a sieve.
Add the lobster and finish
In a mortar, beat the haddock meat, lobster spawn, and body until smooth.
Gradually add this mixture to the soup and stir until smooth.
Bring the soup to a boil again, skim, and add cayenne pepper and wine.
Finally, add the lobster tail and claws, cut into fine pieces, and serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Soften and sweeten, forming the body of the soup base.
- Lobster spawn and body
- Pounded smooth, they enrich the soup with a deep shellfish flavour and colour.
- Haddock meat
- Beaten smooth into the mixture, adding body and a fine, even texture to the soup.
- Rich stock
- Forms the liquid base that carries all the other flavours.
- Lobster tail and claws
- Add fresh, tender pieces of lobster meat for texture and sweet shellfish flavour.
The step that matters
Straining and skimming the stock. Straining removes solids and skimming removes fat and impurities that would cloud the soup and dull its flavour. Doing this before the fish mixture goes in keeps the soup smooth and clean-tasting.
