Cook the vegetables
In a pan, sauté the chopped onions and shredded cabbage in butter until lightly browned.
Sprinkle flour over the vegetables and moisten with stock.

Stir in the wine and tarragon or chervil before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Enriches the flavor and helps the onions and cabbage brown lightly.
- Flour
- Thickens the stock into a richer, more body-filled broth.
- Cabbage
- Adds bulk and a mild, sweet vegetable flavor as it softens.
- Onions
- Build savory sweetness as they brown in the butter.
- Light wine
- Adds acidity and brightness to balance the rich soup.
The step that matters
Skimming during the simmer. Simmering draws scum and impurities to the surface. Skimming them off keeps the broth clear and clean-tasting over the long cook.
Swap the cabbage
