Why it works: Apple and lemon are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 7,551 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Friar’s Omelet
Ingredients
Directions
The book gives no oven temperature. The 350°F (175°C) in the steps was added when the recipe was transcribed, as a starting point.
Prepare the apples
Peel, core, and slice the apples.
In a saucepan, combine apples, sugar, butter, grated lemon rind, and lemon juice. Cook until smooth.
Remove from heat and stir in the beaten egg.
Assemble and bake
In a pie dish, layer half the breadcrumbs, then pour in the apple mixture.
Top with remaining breadcrumbs and a few small pieces of butter.
Bake at 350°F (175°C) for 15 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main body and tart flavor once cooked down into a smooth filling.
- Breadcrumbs
- Soak up the apple mixture and form a soft, layered crumb structure.
- Egg
- Binds the apple mixture so it sets lightly as it bakes.
- Butter
- Adds richness and moisture to the filling and topping.
- Sugar
- Sweetens the apples and helps them cook down smoothly.
The step that matters
Stirring in the beaten egg after removing from heat. If the apple mixture is still very hot when the egg goes in, the egg can scramble into small lumps instead of blending smoothly. Letting it cool slightly first helps the egg thicken the filling evenly during baking.
Swap the apple
How well each one fits the dish's main ingredients (sugar, butter, lemon, egg):
- Vanillafits better
- Orangefits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against sugar, butter, lemon, egg. Candidates are from the same food group and used in at least 100 recipes.
