Why it works: Butter and egg match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and 118,511 recipes mention both. Both carry nonanal, which smells fat, citrus. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set with gentle heat to form a soft, custard-like structure in the milk.
- Milk
- Provides the liquid base that cooks the eggs into a tender, moist texture.
- Butter
- Adds fat for richness and a smoother, silkier mouthfeel.
The step that matters
Cook for 3 more minutes after breaking in the eggs. Egg proteins set as they heat, so a little cooking makes them tender. Cooking too long or too hot tightens them further, making the eggs rubbery or grainy.
“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.
