Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Hard-boiled eggs
- Form the main body of the dish and absorb the creamy sauce as they warm.
- Butter
- Fat that gently cooks the onions and carries flavour into the dish.
- Flour
- Thickens the stock and cream into a smooth, coating sauce around the onions.
- Stock
- Liquid base that moistens the mixture and adds savoury depth.
- Cream
- Adds richness and body, softening the sauce and giving it a silky texture.
The step that matters
Dust the onions with flour. Flour must be cooked briefly in the butter before liquid is added, or it stays floury. Adding the stock and cream too early can leave lumps, so the flour should coat the onions evenly first.
Swap the onion
How well each one fits the dish's main ingredients (egg, butter, flour, cream, pepper):
- Spinachfits better
- Leekfits better
- Chivefits better
- Onionthe original
Fit is the average pairing score against egg, butter, flour, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
