Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Carrots
- Provide the main body, sweetness and earthy flavor of the soup.
- Boiling stock
- Supplies the liquid that softens the chopped carrots as they simmer.
- Sugar
- Adds a touch of sweetness that balances the carrots and lemon.
- Lemon juice
- Adds acidity that brightens the flavor of the soup.
The step that matters
Simmer gently until tender. Carrots cooked at a hard boil can break down unevenly and turn cloudy or stringy. A gentle simmer lets the finely chopped pieces soften evenly and keeps the soup smooth.
Swap the white pepper
How well each one fits the dish's main ingredients (carrot, sugar, onion, parsley, lemon, bread):
- Marjoramfits better
- Thymefits better
- Celeryfits better
