Ingredients
Directions
Prepare the vegetables
Clean and chop the vegetables.
In a frying pan, melt the butter and add the vegetables and sugar.
Fry until they begin to brown slightly, then add a few tablespoons of boiling water.
Simmer for 10 minutes, then transfer to a soup kettle.
Simmer the soup
Add the remaining ingredients except for the corn‑starch and milk, along with 1 quart of boiling water.
Cover and simmer gently for about 2 hours until the vegetables are perfectly soft.
Finish and serve
Mash everything through a sieve and return to the fire with the milk.
When boiling, stir in the corn‑starch blended with a little cold water or milk.
Boil for 2 to 3 minutes and serve immediately with croutons.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Add sweetness and body, and their colour gives the soup its orange tone.
- Onions
- Add savoury depth and flavour as they soften and brown in the butter.
- Butter
- Carries the vegetables' flavour and adds richness when the vegetables are fried.
- Milk
- Adds creaminess and softens the soup's flavour when stirred in at the end.
- Corn-starch
- Thickens the soup as it boils, giving it body.
The step that matters
Stirring in the corn-starch. Corn-starch must be blended with cold liquid first and added while the soup is boiling. Starch added dry or to a cool soup clumps and does not thicken evenly, and it needs a brief boil to reach full thickness.
