Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Provide the main vegetable body and tender texture of the dish.
- Cream
- Forms the rich, smooth body of the sauce and adds moisture and fat.
- Flour
- Thickens the cream into a smooth sauce as it is mixed with butter.
- Butter
- Adds richness and fat, and helps the flour blend smoothly into the sauce.
The step that matters
Mixing the butter and flour until smooth. Flour added to hot cream can clump if not fully blended with the butter first. Working it smooth before it thickens gives an even, lump-free sauce.
Swap the beans
How well each one fits the dish's main ingredients (pork, cream, flour, butter, pepper):
- Almondfits better
- Chestnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against pork, cream, flour, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
