Why it works: Butter and milk are a kitchen classic. They rank in the top 7% of all ingredient pairs, and cooks put them together in 81,283 recipes. Both carry (z)-4-heptenal, which smells biscuit, cream. The science ↓
Omelette Aux Pommes
Ingredients
Directions
Prepare the batter
In a bowl, mix flour, salt, and sugar.
Add eggs, egg yolks, melted butter, and milk. Whisk until smooth.
Cook the omelette
In a large skillet, heat additional melted butter over medium-high heat.
Add sliced apples and sauté until heated through.
Pour the batter over the apples, spreading it evenly.
Pierce the omelette with a fork to let the liquid settle.
Add more melted butter around the edges and tilt the skillet to loosen the omelette.
Once it releases, sprinkle with brown sugar and invert onto a plate.
Grease the skillet again and slide the omelette back in.
Heat until the bottom caramelizes without burning, then invert again to serve.

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Flour and butter barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set the batter into a custard-like structure as they cook.
- Egg yolks
- Add richness and tenderness to the batter.
- All-purpose flour
- Thickens the batter and gives the omelette body.
- Butter
- Adds fat for flavor and helps the omelette brown and release from the pan.
- Milk
- Adds moisture so the batter cooks up soft and pourable.
- Apples
- Provide tender fruit and a fresh, slightly tart flavor.
The step that matters
Caramelizing the bottom before the final invert. Sugar browns into caramel at moderate heat but scorches quickly if the heat is too high. Watching the pan keeps the bottom golden and sweet rather than bitter.
Swap the apple
How well each one fits the dish's main ingredients (flour, sugar, egg, butter, milk):
- Vanillafits better
- Raisinfits better
- Figfits better
- Applethe original
Fit is the average pairing score against flour, sugar, egg, butter, milk. Candidates are from the same food group and used in at least 100 recipes.
