Why it works: Ketchup and sauce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,099 recipes. Both carry ethanol, which smells alcoholic, ethereal. The science ↓
Mock Turtle Soup
Ingredients
Directions
Make the forcemeat balls
Combine veal udder or suet, egg yolks, salt, pepper, and enough flour to bind into balls.
Fry the balls until rich brown.
Make the soup base
In a pot, brown stock with roux.
Add jelly from feet, mushroom ketchup, anchovy sauce, claret or white wine, mace, nutmeg, black pepper, and sweet basil.
Bring to a boil with slices of the head.
Soak and wash pickled pork.
Add the pickled pork to a soup kettle with onions, lemon thyme, sweet basil, celery, and mace.
Add 6-7 quarts of water and boil gently until meat is tender.
Remove meat from bones, chop, and return bones to the pot to simmer longer.
Cool the soup, remove fat, and strain.
Finish and serve
Place the force meat balls in a soup tureen, add lime juice, and pour the soup over them.
Add wine and sauces, then mix in force meat and egg balls.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal udder or suet
- Forms the rich, meaty body of the forcemeat balls.
- Egg yolks
- Bind the forcemeat and help it hold its shape when fried.
- Flour
- Absorbs moisture so the forcemeat balls hold together.
- Mushroom ketchup
- Adds deep savoury, umami flavour to the soup.
- Claret or white wine
- Adds acidity and aromatic depth to the soup.
- Pickled pork
- Lends salty, cured meat flavour to the soup base.
The step that matters
Cool the soup, remove fat, and strain. Fat rises and sets as the soup cools, so chilling lets it be lifted off cleanly. Straining then removes solids, leaving a clear, smooth broth.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
