Ayrshire Soup

Ingredients

Directions

Prepare

  1. Soak the oatmeal in 1 pint of water.

  2. Parboil the sliced potatoes in hot water for 10 minutes.

Make the stock

  1. Combine the chopped vegetables, herbs, meat, and bones in a soup pot with the cold water.

  2. Stew for 4 hours until the liquid reduces by one-third.

  3. Strain through a colander and set aside 2 quarts of stock for later.

Finish the soup

  1. Season the remaining stock and return it to the heat.

  2. Bring to a boil and skim off any foam.

  3. 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.

Swap the turnip

How well each one fits the dish's main ingredients (beef, onion, celery, potato, pepper):

  1. Carrotfits better
  2. Tomatofits better
  3. Chivefits about as well
  4. Turnipthe original

Fit is the average pairing score against beef, onion, celery, potato, pepper. Candidates are from the same food group and used in at least 100 recipes.
