Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mutton steaks
- Provide the main protein, whose flavour and juiciness define the dish.
- Butter
- Adds richness and fat, giving the beans a smooth, silky mouthfeel.
- Egg yolk
- Acts as a binder, thickening the butter and beans into a creamy coating.
- Crumbs of bread
- Forms a light coating on the steaks that adds texture and absorbs juices.
The step that matters
Adding the egg yolk to the beans. Egg yolk thickens when heated gently but curdles and turns grainy if it boils. Keeping the pan moving over low heat lets the yolk thicken the butter smoothly.
Swap the beans
How well each one fits the dish's main ingredients (mutton, pepper, bread, butter, egg):
- Peasfits better
- Lima beansfits better
- Walnutfits about as well
- Beansthe original
Fit is the average pairing score against mutton, pepper, bread, butter, egg. Candidates are from the same food group and used in at least 100 recipes.
