Why it works: Potato and leek share more aroma than cooks usually use. They rank in the top 4% of all ingredient pairs, and 30 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓

Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Method written by CompKitchen from the ingredient list. Not the original author's method, not kitchen-tested.
Trim the root end and dark green tops from the leeks, halve them lengthwise, rinse well under cold water to remove grit, then slice thinly.
Melt the butter in a large pot over medium heat. Add the sliced leeks and cook, stirring, until soft but not browned, about 5 minutes.
Pour in the white wine and simmer until mostly evaporated, about 2 minutes.
Add the potatoes and chicken broth and bring to a boil. Reduce heat to low, cover and simmer until the potatoes are very tender, about 25 minutes.
Remove the pot from the heat. Purée the soup with an immersion blender until smooth, or work in batches in a blender with the lid vented.
Return the soup to low heat and season with salt and the ground white pepper. Stir and warm through for about 3 minutes, adjust seasoning, and serve hot.

Fit is the average pairing score against potato, chicken, leek, butter, white wine. 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).
