Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried green haricots
- Form the bulk of the pudding, providing body once boiled and mashed.
- Butter
- Adds richness and moisture, giving the mash a smoother, softer texture.
- Egg
- Binds the mashed beans so the pudding holds its shape when turned out.
The step that matters
Mashing the cooked haricots thoroughly. Lumps of unmashed bean will stay firm while the rest softens, giving an uneven texture. Thorough mashing breaks down the starch-rich cell walls so the mixture becomes smooth and binds evenly with the egg.
Swap the onion
How well each one fits the dish's main ingredients (butter, pepper, parsley, egg):
- Shallotfits better
- Chivefits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against butter, pepper, parsley, egg. Candidates are from the same food group and used in at least 100 recipes.
