Why it works: Apple and blackberry match in chemistry and in kitchens. They rank in the top 6% of all ingredient pairs, and cooks put them together in 110 recipes. Both carry 1-octen-3-one, which smells mushroom, metallic. The science ↓
Apples, Baked
Ingredients
Directions
The book says “a slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.
Prepare
Pare and core the apples, keeping them whole.
Roll up the apple peel tightly and place it in the center of each apple.
Coat the apples
Brush the apples with egg whites and let them dry.
Re-coat the apples with egg whites.
Sprinkle the apples with castor sugar.
Bake and fill
Place the apples in a pie dish.
Cover the apples with greased paper.
Bake the apples at 300°F (150°C) until tender.
Remove the apple peel from the apples.
Fill the cavity of each apple with your choice of jam or jelly.
Add a small piece of butter to each apple.
Add some brown sugar to each apple if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Apples
- Provide the main structure and soft, moist flesh that becomes tender when baked.
- Egg whites
- Form a thin coating that sets when heated, helping the sugar stick and glaze the skin.
- Castor sugar
- Adds sweetness and helps the coated surface brown and turn glossy in the oven.
- Jam or jelly
- Adds sweetness and fruit flavour to the cavity as the apples bake.
The step that matters
Let the first egg white coat dry before re-coating. A dry first layer gives the second coat something to bond to. Egg white proteins set when heated, so the two coats form an even, glossy shell instead of patchy, sticky spots.
Swap the apple
How well each one fits the dish's main ingredients (egg, sugar, blackberry, butter):
- Vanillafits better
- Peachfits better
- Raspberryfits better
- Applethe original
Fit is the average pairing score against egg, sugar, blackberry, butter. Candidates are from the same food group and used in at least 100 recipes.
