Firenze Biscuits

Oven, in the book's wordsA slack oven

Ingredients

Directions

The book says “a slack oven”. The 350°F in the steps is the modern equivalent, not the book's own figure.

Make the paste

  1. Clarify the sugar in a pan and boil it until it forms a thin thread.

  2. Add the pepper and mixed spices to the sugar.

  3. Incorporate the preserved fruit and boil the mixture for 10 minutes.

  4. Add the whole almonds, half of which should be roasted, and mix well.

  5. Leave the mixture on the heat for a minute, then pour it onto a marble slab dusted with flour.

Shape and bake

  1. Shape the paste into small loaves.

  2. Bake in a moderate oven (350°F / 175°C), covering them with royal icing.

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

What each ingredient does

Sugar
Forms the thread-stage syrup that binds the paste together and gives sweetness.
Almonds
Provide the main body and bite of the paste, and roasted ones add nutty aroma.
Walnuts
Add extra nutty texture and body to the paste.
Preserved fruit
Adds moisture, chewiness and fruity sweetness to the paste.

The step that matters

Boiling the sugar to a thin thread. Sugar must reach the thread stage so the paste sets firm enough to shape into loaves; underheating leaves it soft and sticky, while overheating makes it hard and brittle once cooled.

Swap the walnut

How well each one fits the dish's main ingredients (sugar, almond, pepper, cinnamon, clove, nutmeg):

  1. Chestnutfits better
  2. Pistachiofits better
  3. Cashew nutfits better
  4. Walnutthe original

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