Why it works: Apple and clove are a kitchen classic. They rank in the top 6% of all ingredient pairs, and cooks put them together in 2,774 recipes. Both carry ethyl octanoate, which smells fruity, wine. The science ↓

Apple Biscuit

Oven, in the book's wordsA very slow oven

Ingredients

Directions

The book says “a very slow oven”. The 300°F (150°C) in the steps is the modern equivalent, not the book's own figure.

Prepare the apple pulp

  1. Boil the apples in water until soft.

  2. Remove the apples and rub them through a wire sieve.

  3. Flavor the pulp with a drop or two of essence of lemon and, if desired, a drop of oil of cloves.

  4. Add lump sugar equal in weight to the pulp and grind it together.

Shape and dry

  1. Roll the sugared pulp into flat cakes about ¼ inch thick and cut into shapes.

  2. Dry the cakes in a very slow oven at 300°F (150°C) or in the summer sun until fully dried.

Transcribed from a scanned cookbook and modernised for today's kitchens. Where the book gave no heat or time, or said "a moderate oven", the temperatures and times here may be modern equivalents rather than the book's own figures.

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

What each ingredient does

Apples
Provide the pulp that becomes the body of the biscuit.
Lump sugar
Sweetens the pulp and helps it firm up as it dries.

The step that matters

Dry the cakes until fully dried. Sugar and fruit pulp only hold their shape and keep well once most of their water has evaporated. Drying too briefly leaves the biscuits soft and prone to spoiling, while a very hot oven can scorch the sugar before the centre is dry.

Swap the lemon

The recipe marks lemon as optional. How well each one fits the dish's main ingredients (apple, clove, sugar):

  1. Quincefits better
  2. Pearfits better
  3. Vanillafits better
  4. Lemonthe original

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