Why it works: Lettuce and carrot match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and 975 recipes mention both. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Boston lettuces
- Provide the leafy body and fresh, mild flavour of the soup.
- Yolks
- Thicken the soup and add richness when beaten into the liquid.
- Vinegar
- Adds the sour acidity that gives this soup its character.
- Sour cream
- Adds tang and body, smoothing the soup as it is blended in.
- Eggs
- Set into a solid omelette that forms the garnish strips.
- Smoked bacon
- Adds smoky, savoury fat and flavour to the omelette strips.
The step that matters
Let the soup come to just one boil. Egg yolks thicken and can curdle if the soup boils hard after they are added, so heat should be kept gentle at this point.
Flavor stand-ins for the garlic
The recipe marks garlic as optional. How well each one fits the dish's main ingredients (lettuce, carrot, parsley, onion, flour, cream, vinegar):
- Celerybetter flavor fit
- Tarragonabout as good a flavor fit
- Dillabout as good a flavor fit
- Garlicthe original
Fit is the average pairing score against lettuce, carrot, parsley, onion, flour, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
