Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melts to coat the vegetables and carry flavor, adding richness during gentle braising.
- Carrots
- Provide the main bulk, sweetness and color of the soup.
- Turnips
- Add bulk and a mild, slightly peppery sweetness to the soup.
- Leeks
- Add a mild onion-like aroma and body to the soup.
- Onions
- Add aroma and savory depth as they soften in the butter.
- Powdered sugar
- Encourages browning and rounds out the vegetables' sweetness.
The step that matters
Braise the vegetables slowly until they begin to soften. Low heat draws out moisture and sweetness gently. If the heat is too high, the butter and sugar can scorch before the vegetables soften, leaving bitter flavors.
