Why it works: Chanterelle and flour share more aroma than cooks usually use. They rank in the top 3% of all ingredient pairs, and 32 recipes mention both. Both carry isobutyraldehyde, which smells malty, green. The science ↓
The recipe
Ingredients
Contains: milk, wheat, shellfish (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Make the soup base
Put potatoes, mushrooms, garlic, bay leaf, savory, marjoram, salt, and pepper into a medium stockpot.
Cover with about 6 cups of cold water.
Cook over medium heat until it boils, then reduce heat and cook for 20 to 30 minutes.
Make the roux and finish
In a separate small saucepan, heat the cooking oil over medium-high heat.
When hot, sprinkle in the flour and shallots.
Brown to make a roux, stirring constantly.
Add some of the cooking liquid from the soup to thin the roux out and pour it into the soup.
Bring to a gentle boil and remove from heat.
Add the tarragon vinegar before serving.
Garnish with chopped chives and sour cream.
For a lighter version, add low-fat sour cream.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Potatoes
- Break down during simmering to give the soup body and a thick, creamy texture.
- Mushrooms
- Contribute earthy, savory flavor and a meaty texture to the broth.
- All-purpose flour
- Browned in oil to form a roux that thickens the soup.
- Sour cream
- Adds richness and a cool, tangy finish when stirred in or spooned on top.
- Tarragon vinegar
- Adds acidity that brightens the flavor and balances the richness of the soup.
The step that matters
Browning the roux. Flour cooked in hot oil must be stirred constantly; if it scorches it turns bitter, and if it is not cooked enough it tastes raw and thickens poorly.

Fit is the average pairing score against potato, oyster, chanterelle, mushroom, garlic, pepper, flour. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
