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.

Make the paste

  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 lemon essence and, if desired, a drop of oil of cloves.

  4. Add lump sugar equal in weight to the pulp and grind them 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 slow oven at 300°F (150°C) or in the summer sun until partially dried.

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 forms the body and structure of the cakes.
Lump sugar
Adds sweetness and helps bind the pulp into a firm, shapeable paste.
Oil of cloves
Adds a warm, spicy aroma to the pulp.

The step that matters

Drying the cakes. Drying in a slow oven or sun removes moisture gradually, so the cakes firm up and hold their shape without browning or cracking. Too much heat can scorch the sugar and harden the outside before the inside has dried.

Swap the lemon

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.
