Why it works: Apple and butter are a kitchen classic. They rank in the top 14% of all ingredient pairs, and cooks put them together in 8,706 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓
Friars Omelet
Ingredients
Directions
The book says “a good oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare the apples
Pare and core the apples.
Stew the apples with sugar and butter until they turn into a pulp.
Let the mixture cool.
Assemble and bake
Stir in the beaten eggs.
Grease a pie dish and line it with breadcrumbs.
Pour the apple mixture into the dish and cover with more breadcrumbs.
Bake for 1 hour at 400°F (200°C).
Serve
Turn out the omelet and sprinkle sugar over it.

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.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Break down into a pulp to form the body of the omelet and provide sweetness.
- Eggs
- Bind the apple pulp and set during baking to give the omelet structure.
- Butter
- Adds richness and fat, carrying flavor and softening the apple pulp.
- Breadcrumbs
- Form a crisp, lightly browned coating on the dish and top of the omelet.
The step that matters
Let the mixture cool before adding the eggs. If the stewed apple is still hot, it can scramble the beaten eggs instead of blending smoothly. Cooling first keeps the eggs fluid so they set evenly into a uniform custard-like layer during baking.
Swap the apple
How well each one fits the dish's main ingredients (butter, egg, sugar):
- Vanillafits better
- Lemonfits better
- Raisinfits better
- Applethe original
Fit is the average pairing score against butter, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
