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 (175°C) in the steps is the modern equivalent, not the book's own figure.
Make the filling
In a bowl, combine mincemeat, powdered sugar, lemon rind, lemon juice, clarified butter, and egg yolks, then beat well together.
Line pattypans with fine pastry and fill them more than half full with the mixture.
Bake and ice
Bake in a 350°F (175°C) oven until the insides are just set.
In another bowl, beat egg whites until stiff peaks form, then quickly mix in powdered sugar.
Ice the pies thickly with the egg white mixture and return to the oven.
Bake slowly until the icing is 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, adding sweetness, spice and moisture to the pies.
- Egg yolks
- Enrich and bind the filling, helping it set firm when baked.
- Egg whites
- Whipped into a meringue-like icing that bakes to a light, crisp brown topping.
- Clarified butter
- Adds richness and fat, giving the filling a smooth, tender texture.
- Powdered sugar
- Sweetens the filling and dissolves into the whites to stabilise the icing.
The step that matters
Baking the icing slowly. Egg white icing can brown too fast or weep if the oven is too hot. A slow bake dries and sets the meringue evenly while it turns light brown.

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).
