Why it works: Lemon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 41,227 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓
Mince Pies Royal
Ingredients
Directions
The book says “a moderate oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.
Make the filling
Combine mincemeat, pounded sugar, lemon rind, lemon juice, clarified butter, and egg yolks in a bowl and beat well together.
Fill pattypans lined with fine pastry about half full with the mixture.
Bake in a moderate oven (350°F / 175°C) until just set.
Ice and finish
Beat egg whites until stiff in another bowl, then quickly mix in pounded sugar.
Ice the pies thickly with the egg white mixture.
Return to the oven and bake slowly until they are a fine light brown.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Mincemeat
- Provides the main filling, sweetness and spiced fruit flavour.
- Egg yolks
- Bind the filling and help it set when baked.
- Egg whites
- Whipped into a meringue topping that bakes to a light brown crust.
- Clarified butter
- Adds richness and moisture to the filling.
- Pounded sugar
- Sweetens the filling and the meringue topping.
The step that matters
Folding the sugar into the whites. Egg whites beaten until stiff hold their foam only if sugar is added quickly, before they lose volume. Overbeating or delay can make the topping weep or collapse in the oven.
Flavor stand-ins for the lemon

Fit is the average pairing score against sugar, butter, egg. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
