Millefruit Rock Candy

Ingredients

Directions

The book gives no oven temperature. The 400°F in the steps was added when the recipe was transcribed, as a starting point.

Prepare the box

  1. Prepare a tin box with a small hole at the bottom and insert a cork.

  2. Layer the bottom with paste knots and angelica knots, placing a wire between each layer.

Make and bake the syrup

  1. Boil the syrup until it reaches a blow stage, then pour it over the layers in the tin box.

  2. Let it stand in a very hot oven (400°F / 200°C) for 3 hours.

  3. Remove the cork and let the syrup drain for 30 minutes.

Make the topping and finish

  1. In a pan, boil 1 pint of syrup until almost caramelized.

  2. Mix the egg white with powdered sugar until thick.

  3. Stir the egg and sugar mixture into the boiling syrup quickly.

  4. Pour the mixture into a sieve and let it cool until hard.

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

What each ingredient does

Syrup
Forms the clear candy matrix that sets hard as it cools.
Egg white
Whipped with sugar and stirred into syrup to create a light, opaque, hardened coating.
Powdered sugar
Combines with the whipped egg white to form a thick mixture that adds sweetness and body.
Paste knots
Dried fruit-paste pieces that hold their shape and add flavour and colour within the candy.
Angelica knots
Candied pieces that keep their shape and add flavour and colour within the candy.

The step that matters

Boiling the syrup to the blow stage. Syrup boiled to too low a temperature stays soft and sticky, while overcooking turns it brittle or caramelized. The correct stage is needed so the candy sets firm but not burnt.

Swap the angelica

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

  1. Cinnamonfits better
  2. Nutmegfits better
  3. Gingerfits better
  4. Angelicathe original

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