Why it works: Butter and bread are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 27,232 recipes. Both carry delta-decalactone, which smells sweet, creamy. The science ↓
Potato Soup with Stock
Ingredients
Directions
Make the stock
In a large pot, combine soup meat, soup vegetables, and water, then bring to a boil.
Reduce heat and simmer for 3.5 hours.
Allow the stock to cool, then remove all grease.
Make the soup
Strain 2 quarts of stock into a pot.
Add milk, cream, and grated potatoes to the stock.
Stir in butter, flour, pepper, and salt, then bring to a boil.
Strain the soup through a wire sieve.
Garnish and serve
Toast the slice of bread, then cut it into ½ inch cubes.
Fry the bread cubes in hot lard until golden, then drain.
Serve the soup in a tureen and add the fried bread cubes if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Soup meat
- Gives the stock its deep, savory meaty flavor during long simmering.
- Potatoes
- Break down as they cook, thickening the soup and giving it body.
- Butter
- Adds richness and a smooth, rounded mouthfeel to the finished soup.
- Flour
- Thickens the soup as it heats, giving it a smoother, heavier texture.
- Milk
- Adds creaminess and mild sweetness, softening the soup's savory notes.
- Cream
- Adds fat and richness, producing a silkier, fuller texture.
The step that matters
Remove all grease from the cooled stock. Fat that is left in the stock can make the finished soup feel greasy and heavy. Chilling and cooling lets the fat rise and set so it can be lifted off cleanly.
