Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Veal
- Provides the meat that becomes tender during the long simmer.
- Flour
- Thickens the stock into a smooth, body-rich sauce.
- Cream
- Adds richness and a smooth, mellow texture to the sauce.
- Hard-boiled eggs
- Add body and a soft, finely chopped texture to the sauce.
- Butter
- Carries the onion flavor and adds richness to the start of the stew.
The step that matters
Add the cream, chopped eggs, and lemon juice. Cream can curdle or separate if it boils hard after being added to an acidic mixture. Keep the stew at a gentle heat once the lemon juice goes in.
Swap the onion
How well each one fits the dish's main ingredients (veal, butter, flour, mushroom, ketchup, pepper, cream):
- Shallotfits better
- Capsicumfits better
- Leekfits about as well
