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

What each ingredient does

Sun-dried turtle
Forms the main meat; long soaking rehydrates it and long simmering makes it tender.
Good stock
Serves as the liquid base that carries the flavour of the whole soup.
Onions
Release sweetness and savoury depth as they simmer slowly in the stock.
Celery
Adds aromatic background flavour as it softens during the long simmer.
Carrot
Contributes gentle sweetness and body to the stock as it cooks down.
Bay leaves
Add a subtle aroma that infuses the stock during long boiling.

The step that matters

Add more stock as it reduces by boiling. Boiling evaporates water and concentrates flavour, so the liquid must keep covering the meat. Topping up keeps the turtle cooking evenly and stops the stock from scorching or becoming overly salty and intense.

Swap the onion

How well each one fits the dish's main ingredients (celery, carrot, turnip, leek, marjoram, thyme, parsley):

  1. Parsnipfits better
  2. Shallotfits better
  3. Lettucefits better
  4. Onionthe original

Fit is the average pairing score against celery, carrot, turnip, leek, marjoram, thyme, parsley. Candidates are from the same food group and used in at least 100 recipes.
