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 ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Form the main topping, adding substance, protein-based body and a mild rich flavor.
- Butter
- Adds fat for richness and a smooth mouthfeel that complements the eggs.
- Soft toast
- Provides a base that holds the sliced eggs and soaks up the melted butter.
The step that matters
Boiling the eggs for 20 minutes. Boiling for this long can overcook the yolks, producing a dry, crumbly texture and a greyish-green ring. The green ring forms when sulfur in the white reacts with iron in the yolk at high heat, so timing and cooling affect the result.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
