Directions
Make the broth
Put the meat into 3 pints of water with the onions, turnip, and salt.
Bring to a boil, skim thoroughly, and let it gently boil for 3 hours.
Strain the broth and let it cool to remove the fat.
Thicken and serve
Reheat the broth, stir in the potato flour mixed with milk or cream, and let it thicken.
Season to taste and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Meat
- Gives the broth its savoury, meaty flavour as it simmers.
- French potato flour
- Thickens the broth to a smooth, lightly body-filled consistency when stirred in and reheated.
- Milk or cream
- Adds richness and a softer, creamier texture to the thickened broth.
- Onions
- Contribute sweetness and aromatic depth to the stock.
- Turnip
- Adds earthy, subtly sweet flavour to the broth.
The step that matters
Skim the broth thoroughly after it comes to a boil. Foam and fat rise to the surface as the broth heats. Removing them early keeps the broth clear and prevents greasy, cloudy results before the long simmer.
Swap the onion
The recipe marks onion as optional. How well each one fits the dish's main ingredients (meat, turnip, potato, flour, milk, mutton, thyme):
- Leekfits better
- Shallotfits better
- Parsnipfits better
- Onionthe original
Fit is the average pairing score against meat, turnip, potato, flour, milk, mutton, thyme. Candidates are from the same food group and used in at least 100 recipes.
