Marrons Glace

Ingredients

Directions

Prepare the chestnuts

  1. Remove shells from chestnuts.

  2. Cover chestnuts with boiling water and let stand for a few minutes to remove skins.

  3. Simmer chestnuts in hot water until tender but not soft.

Make the syrup and cook the chestnuts

  1. Combine sugar and water in a saucepan. Stir until dissolved.

  2. Add boiled chestnuts to the syrup and cook until they look clear.

  3. Turn chestnuts onto a sieve to cool.

  4. Return strained syrup to saucepan and cook to hard‑ball stage.

Coat and set

  1. Remove from heat and add lemon juice and vanilla extract.

  2. Drop chestnuts into syrup one at a time, turning until thinly coated.

  3. Remove chestnuts with a candy wire to an oiled paper or slab.

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

What each ingredient does

French chestnuts
Provide the main body of the candy, becoming tender when simmered and then sweetened.
Sugar
Forms the syrup that cooks to hard-ball stage and gives the candied coating its sweetness and set.
Lemon juice
Adds acidity that helps keep the sugar syrup from crystallising.

The step that matters

Cooking the syrup to hard-ball stage. Syrup that is cooked too little stays sticky and will not set on the chestnuts, while overcooking makes the coating brittle or gritty. Stopping at the right temperature controls the final texture of the candy.

Swap the lemon

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

  1. Figfits better
  2. Cherryfits better
  3. Pearfits better
  4. Lemonthe original

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