Mock Turtle Soup
Ingredients
Directions
Prepare the head
Soak the turtle head and tongue in saltwater for 1.5 hours.
Place the head in a pot with 1 tablespoon salt and enough cold water to cover it.
Simmer gently for 30 minutes, then remove the head and skim the pot.
Make the stock
Add the beef, onion with cloves, salt, bay leaves, peppercorns, carrots, turnips, and celery to the pot.
Cut the meat and skin from the head, break the bones, and add them to the pot with the beef and vegetables.
Add the sweet herbs and parsnip, then stew for 3 hours.
Remove the bones, strain the liquid, and pound the vegetables, beef, and spices.
Mix the pounded mixture with the liquid and simmer for another 30 minutes.
Strain through a fine sieve and return the gravy to the pot.
Finish and serve
Cut the meat and skin from the head into 2-inch pieces and add to the pot with 2 teaspoons salt and mushrooms.
Simmer for 3.5 hours, skimming carefully before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Turtle head
- Supplies gelatinous meat, skin and bones that give the soup its body and rich texture.
- Beef
- Adds deep meaty flavour and collagen that thickens the stock as it stews.
- Onion
- Builds savoury sweetness and aromatic depth as it cooks slowly in the stock.
- Carrots
- Contribute gentle sweetness and body to the stock during long simmering.
- Celery
- Adds aromatic, savoury background flavour to the stock.
- Button mushrooms
- Add earthy umami flavour and a tender texture to the finished soup.
The step that matters
Skimming the pot during the long simmer. Proteins and fats rise to the surface as foam and scum; removing them keeps the broth clear and prevents a greasy or cloudy taste.
Swap the clove
How well each one fits the dish's main ingredients (beef, onion, carrot, turnip, celery, parsnip, mushroom):
- Thymefits better
- Parsleyfits better
- Marjoramfits better
