Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Thickens the butter and liquids into a smooth, body-rich soup.
- Butter
- Adds fat and richness, and carries the flour into a smooth roux.
- Milk
- Adds creaminess and body, giving the soup a rich, mellow texture.
- Asparagus pulp
- Provides the main asparagus flavour and thickens the soup as it cooks.
The step that matters
Stirring the flour into the melted butter until smooth. Flour added to fat must be fully blended before liquid goes in, or lumps form that stay in the finished soup. Stirring it smooth first lets the starch disperse evenly.
Swap the white pepper
How well each one fits the dish's main ingredients (flour, butter, milk, asparagus, nutmeg):
- Cinnamonfits better
- Cardamomfits better
- Tarragonfits better
- White pepperthe original
Fit is the average pairing score against flour, butter, milk, asparagus, nutmeg. Candidates are from the same food group and used in at least 100 recipes.
