Why it works: Egg and butter are a kitchen classic. They rank in the top 17% of all ingredient pairs, and cooks put them together in 118,967 recipes. Both carry decanal, which smells soap, orange peel. The science ↓

Ingredients
Directions
The book says “a moderate oven”. The 350°F (175°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Preheat the oven to 350°F (175°C).
Cover the bottom of an earthen baking dish with well-seasoned tomato puree.
Assemble and bake
Arrange poached eggs on the puree, leaving spaces to show the red color.
Lay whole small sausages or 1-inch pieces of sausage between the eggs.
Place a small piece of butter on each egg.
Heat the dish in the oven until warmed through.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Tomato puree
- Forms the moist red base that the eggs sit in and adds acidity and savory flavor.
- Poached eggs
- Provide the main protein, setting as the dish heats and giving a soft, rich texture.
- Sausages
- Add savory, fatty flavor and a firmer texture against the soft eggs.
- Butter
- Adds richness and a silky mouthfeel as it melts over the eggs.
The step that matters
Heat the dish in the oven until warmed through. Poached eggs are already cooked, so the oven only needs to warm them. Overheating can make the yolks dry and rubbery and toughen the whites.
Swap the tomato
How well each one fits the dish's main ingredients (egg, butter):
- Asparagusfits better
- Chivefits better
- Leekfits better
- Tomatothe original
Fit is the average pairing score against egg, butter. Candidates are from the same food group and used in at least 100 recipes.
