Why it works: Butter and flour are a kitchen classic. They rank in the top 12% of all ingredient pairs, and cooks put them together in 124,287 recipes. Both carry isobutyraldehyde, which smells malty, green. The science ↓
Lincoln Pie
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.
Make the filling
Preheat the oven to 350°F (175°C).
Combine the stewed apples, butter, flour, lemon rind, lemon juice, and beaten egg yolks in a bowl. Sweeten to taste.
Pour the mixture into a pie crust and bake until set.
Top and brown
Whip the egg whites until soft peaks form, then gradually add 3 tablespoons of sugar until stiff peaks form.
Spread the meringue over the baked pie and brown in the oven for a few minutes.

Butter and flour 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
- Egg yolks
- Thicken the filling and enrich it, helping it set when baked.
- Egg whites
- Whipped with sugar to form a stable, airy meringue topping.
- Butter
- Adds fat for richness and a tender texture in the filling.
- Flour
- Helps thicken the filling so it holds its shape when set.
- Stewed sour apples
- Provide the main body and tart flavour of the filling.
The step that matters
Whipping the egg whites to stiff peaks. Sugar must be added gradually to whipped whites so they form a stable, glossy foam. Underwhipped or overmixed whites will weep or collapse in the oven, leaving a thin or soggy meringue.
Swap the apple
How well each one fits the dish's main ingredients (butter, flour, lemon, egg, sugar):
- Raisinfits better
- Vanillafits better
- Figfits better
- Applethe original
Fit is the average pairing score against butter, flour, lemon, egg, sugar. Candidates are from the same food group and used in at least 100 recipes.
