Why it works: Butter and mushroom are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 12,525 recipes. Both carry trans-2-decenal, which smells waxy, orange. The science ↓
Fricassee Eggs
Ingredients
Directions
Make the sauce
Melt the butter in a saucepan.
Stir in the flour until smooth.
Add the gravy or stock and season with salt and pepper.
If using canned mushrooms, add them and cook for 5 minutes; if fresh, cook them in the butter before adding the flour.
Finish and serve
Slice the hard-boiled eggs and add them to the sauce.
Let the sauce boil once and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Provides fat and richness, and forms the base for thickening the sauce with flour.
- Flour
- Thickens the sauce by combining with the butter and absorbing the liquid.
- Gravy or stock
- Forms the liquid base of the sauce and supplies savory flavor.
- Hard-boiled eggs
- Add substance and a creamy, rich texture to the sauce.
- Mushrooms
- Add earthy, savory flavor and a little moisture to the sauce.
The step that matters
Stir in the flour until smooth. Flour must be fully blended into the melted butter so its starch disperses evenly. Stirring it smooth before the liquid goes in helps prevent lumps and lets the sauce thicken evenly as it heats.
