Why it works: Turnip and celery are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 4,418 recipes. Both carry coumarin, which smells sweet, hay. The science ↓
Ayrshire Soup
Ingredients
Directions
Prepare
Soak the oatmeal in 1 pint of water.
Parboil the sliced potatoes in hot water for 10 minutes.
Make the stock
Combine the chopped vegetables, herbs, meat, and bones in a soup pot with the cold water.
Stew for 4 hours until the liquid reduces by one-third.
Strain through a colander and set aside 2 quarts of stock for later.
Finish the soup
Season the remaining stock and return it to the heat.
Bring to a boil and skim off any foam.
Add the soaked oatmeal and stew, covered, for 40 minutes, stirring often to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lean beef
- Breaks down during long stewing, giving the stock its deep, meaty flavour.
- Marrow bones
- Release collagen and fat during long simmering, adding body and richness to the stock.
- Potatoes
- Their starch thickens the soup as they cook and begin to break down.
- Oatmeal
- Its starch swells in the hot liquid, thickening the soup and giving it a soft texture.
- Onions
- Their sugars and aromatic compounds build the savoury base of the stock.
- Turnips
- Add mild sweetness and earthy flavour as they soften in the stock.
The step that matters
Stirring in the oatmeal. Oatmeal starch thickens the liquid and settles quickly, so it scorches on the bottom of the pot if not stirred often. Scorched bits give a burnt taste to the whole soup.
