Why it works: Turnip and parsnip match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 590 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Beef Soup
Ingredients
Directions
Make the broth
Place the soup bone in a pot and cover it with cold water.
Simmer for several hours, starting early in the morning.
Remove any scum that forms on the surface.
If using, add the sirloin steak along with the bones.
Add vegetables and finish
Add sliced vegetables of your choice to the pot.
Ensure the soup does not boil too much to keep the vegetables tender.
Add salt and catsup just before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup bone (shank)
- Releases collagen and flavour into the water as it simmers, giving the broth body and savour.
- Sirloin steak
- Adds beefy flavour and some meat to the broth.
- Potatoes
- Soften during simmering and thicken the broth slightly as their starch releases.
The step that matters
Keep the simmer gentle. A hard boil makes the broth cloudy and breaks the vegetables apart, while gentle simmering keeps the soup clear and the vegetables tender.
Swap the tomato
How well each one fits the dish's main ingredients (potato, turnip, parsnip, carrot, cabbage, onion, celery):
- Leekfits better
- Beetrootfits better
- Broccolifits better
