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 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 thin strips of 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 half a bottle of sweet wine over the apples, ensuring the tops are moistened.
Sift white sugar thickly over the apples.
Bake in a very hot oven (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
- Norfolk biffins
- Firm-fleshed apples that hold their shape and soften gradually during slow baking.
- Pale brown sugar
- Forms a thick syrup with the wine that sweetens and glazes the apples as they bake.
- Sweet wine
- Moistens the apples and mingles with the sugar to create a flavourful syrup in the tin.
- Candied orange peel
- Adds concentrated sweetness and aromatic citrus flavour inside the apple cavities.
- Lemon rind
- Contributes aromatic oils and a bright citrus note that balances the sweetness.
The step that matters
Searing the outsides in a very hot oven. The outsides must catch and darken at high heat to build caramelised flavour, but they can burn before the interior softens. Reducing the heat afterward lets the centre cook through gently without the exterior turning bitter.
Swap the raisin
How well each one fits the dish's main ingredients (lemon, orange, sugar):
- Limefits better
- Vanillafits better
- Blueberryfits better
- Raisinthe original
Fit is the average pairing score against lemon, orange, sugar. Candidates are from the same food group and used in at least 100 recipes.
