Why it works: Barley and carrot match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 784 recipes. Both carry 2-nonenal, which smells fatty, green. The science ↓
Round the Table
Ingredients
Directions
Make the base
Put an ounce of butter into a saucepan with three large onions, shred fine, and fry them a pale brown colour.
Add half a tablespoonful of flour and stir for a few minutes without letting the mixture darken.
Add one quart of stock and stir until the soup boils.
Season to taste with powdered pepper and salt.
Add the vegetables and finish
Peel one or two potatoes, cut them into small dice, and boil them with the soup.
Cut crust of stale bread into long pieces, dry them in the oven, and throw them into the soup at serving.
Stir the soup off the fire with the yolks of two eggs beaten up with a little milk and strained.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Onions
- Frying them to a pale brown builds the sweet, savoury base of the soup.
- Flour (in the method)
- Stirred into the fried onions, it thickens the soup slightly.
- Potatoes
- Boiled in the soup until tender, they break down and add body.
- Eggs
- Egg yolks stirred in off the heat enrich the soup and thicken it smoothly.
The step that matters
Stirring in the egg yolks off the fire. Egg yolks thicken by gentle heat. If the soup is kept boiling when they go in, they can scramble and turn grainy, so the soup should be off the heat when they are stirred in.
