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
- Provide the main protein topping, adding richness and a soft, creamy texture.
- Soft toast
- Forms the base that holds the sliced eggs and adds a soft, bready texture.
- Butter
- Adds fat for richness and a smooth mouthfeel that carries flavour.
The step that matters
Boil the eggs for 20 minutes. Boiling too long can leave a grey-green ring around the yolk. This comes from a reaction between sulfur in the white and iron in the yolk, and it is more likely with prolonged heat and slow cooling.
“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.
