Why it works: Milk and cheese are a kitchen classic. They rank in the top 10% of all ingredient pairs, and cooks put them together in 4,426 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
Koob's Quiche
Ingredients
Directions
Prepare the crust
Bake the pie crust according to its instructions (usually at a different temperature than the quiche; in this case 400°F).
Let the pie crust cool before adding the quiche ingredients.
While the crust is cooling, reduce the oven temperature to 375°F.
Make the filling
While the pie crust is baking, combine eggs, milk, cheese, bell peppers, onion, salt, and pepper in a bowl.
Once the crust is cool, pour the quiche mixture into it.
Bake and serve
Carefully slide the pie crust and quiche mixture into the 375°F oven and bake for 50–60 minutes.
When the top is golden brown and the eggs are set, remove the quiche from the oven and let it cool.
Cut the quiche into individual slices and serve.
Nutrition, whole recipe (rough)

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Set into a custard that holds the filling together when sliced.
- Milk
- Adds moisture and creaminess, diluting the eggs for a tender texture.
- Cheese
- Melts into the custard, adding richness, fat and savory flavor.
- Green bell pepper
- Adds moisture and a fresh, slightly bitter vegetable flavor.
- Red bell pepper
- Adds moisture, mild sweetness and color to the filling.
- Sweet onion
- Adds sweetness and aromatic flavor that mellows during baking.
The step that matters
Let the crust cool before adding the filling. A hot crust keeps melting the butter and softening the pastry, so it can turn soggy. Cooling it first helps the base stay crisp under the liquid custard.
Swap the onion
How well each one fits the dish's main ingredients (egg, milk, cheese, pepper):
- Capsicumfits better
- Potatofits better
- Asparagusfits better
- Onionthe original
Fit is the average pairing score against egg, milk, cheese, pepper. Candidates are from the same food group and used in at least 100 recipes.
