Why it works: Lemon and orange match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 10,634 recipes. Both carry 3-hexenal, which smells apple, fruity. The science ↓

Ingredients
Directions
The book says “a very hot oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Cut the biffins in half without peeling them and scoop out the cores.
Fill the cavities with lemon rind and candied orange peel.
Cover the bottom of a flat shallow tin with a thick layer of brown sugar.
Press the two halves of each apple together and place them closely in the tin.
Bake and serve
Pour the sweet wine over the apples, ensuring the tops are moistened.
Sift white sugar thickly over the apples.
Bake in a very hot oven at 400°F (200°C) until the outsides catch or become black.
Then reduce the heat and bake gently until the apples are soft throughout.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Biffins
- Firm apples hold their shape and soften evenly through long gentle baking.
- Brown sugar
- Melts into a syrup that caramelises against the apples and sweetens the dish.
- Sweet wine
- Adds moisture and sweetness, and its sugars help the tops darken as they bake.
- Candied orange peel
- Adds concentrated sweetness and citrus aroma inside the apple cavities.
- Lemon rind
- Adds bright acidity and aromatic oils that cut through the sweetness.
The step that matters
Bake in a very hot oven until the outsides catch. Dark caramelised surfaces develop from sugars browning at high heat, but if the apples are left too long they can burn before the flesh softens. The gentle second stage lets the interior cook through evenly.
