Why it works: Lemon and butter are a kitchen classic. They rank in the top 16% of all ingredient pairs, and 41,227 recipes mention both. 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.
Prepare the filling
Combine the mincemeat, pounded sugar, lemon rind, lemon juice, clarified butter, and egg yolks in a bowl and mix well.
Fill pattypans lined with pastry about three-quarters full with the mixture.
Bake and ice
Bake in a 350°F (175°C) oven until the filling is just set.
Beat the egg whites until stiff, then quickly mix in the pounded sugar.
Spread the icing thickly over the pies 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, sweetness and spiced fruity flavour.
- Egg yolks
- Enrich and bind the filling so it sets when baked.
- Egg whites
- Whipped to stiff peaks to form a light, airy icing that browns in the oven.
- Clarified butter
- Adds richness and fat for a tender filling.
- Pounded sugar
- Sweetens the filling and, whipped with egg whites, forms the crisp icing.
The step that matters
Baking the icing slowly. Meringue-style icing made from whipped egg whites is sugar-rich and browns quickly; a slow, moderate oven lets it dry and turn light brown without scorching or weeping.

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).
