Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Butter
Frying the vegetables in butter builds a pale brown, savoury flavour base.
Flour
Stirred into the fried vegetables and butter, it thickens the stock into a smooth body.
Lobster
Supplies the main sweet, rich seafood flavour and tender meat for the soup.
Fish stock
Forms the liquid base that carries the flavour of the vegetables and lobster shell.
Milk
Adds creaminess and softens the flavour of the soup near the end.
Carrot, turnip and celery
Provide sweetness and aromatic depth as they cook slowly in the stock.

The step that matters

Frying the vegetables until pale brown. Browning the vegetables gently in butter builds flavour, but over-browning turns them bitter and dark. Stop when they are pale brown, then add the flour so it cooks briefly without scorching.

Swap the celery

How well each one fits the dish's main ingredients (lobster, fish, milk, butter, flour, carrot, turnip):

  1. Capersfits better
  2. Parsleyfits about as well
  3. Celerythe original
  4. Tarragonfits about as well

Fit is the average pairing score against lobster, fish, milk, butter, flour, carrot, turnip. Candidates are from the same food group and used in at least 100 recipes.
