To Make Black Caps

Oven, in the book's wordsA quick oven

Ingredients

Directions

The book says “a quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.

Prepare and bake

  1. Cut off a slice at the blossom end of each apple.

  2. Place the apples in a tin and bake in a 400°F (200°C) oven until brown.

Glaze and finish

  1. Wet the apples with rose water and sprinkle with lump sugar.

  2. Return the apples to the oven until they look bright and black.

  3. Transfer the apples to a deep china dish or plate and pour thick cream custard or white wine sugar around them.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Apples
Their flesh softens and their sugars caramelise on the surface as they bake, giving the dessert its body.
Lump sugar
Melts and caramelises on the hot apple surface, adding sweetness and a dark, glossy browning.
Rose water
Adds a delicate floral aroma to the apples.

The step that matters

Returning the apples to the oven until they look bright and black. Sugar caramelises quickly at high heat, so the apples can go from glossy to burnt within minutes. Checking them often keeps the sugar dark and glossy without bitterness.

Swap the apple

How well each one fits the dish's main ingredients (rose, sugar, cream):

  1. Vanillafits better

Fit is the average pairing score against rose, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
