Chestnuts, Candied

Ingredients

Directions

Make the syrup

  1. Combine ½ cup water, sugar, and beaten egg white in a lined saucepan.

  2. Heat until the sugar dissolves, then bring to a boil.

  3. Add 1 cup of cold water and bring back to a boil.

  4. Remove the pan from heat and skim off any scum.

Prepare the chestnuts

  1. Peel the outer skin from the chestnuts.

  2. Boil the chestnuts in water until the second skin can be easily removed.

  3. Boil the chestnuts until tender.

  4. Squeeze the juice of the lemons and mix with a little lukewarm water.

  5. Add the chestnuts to the lemon mixture.

Candy and dry

  1. Once cooled, use a long pin to dip each chestnut in the syrup.

  2. Place the dipped chestnuts on a greased surface to dry.

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

What each ingredient does

Sugar
Forms the syrup that coats the chestnuts and becomes a crisp, sweet candy shell as it dries.
Chestnuts
Provide the starchy, tender base that the sugar syrup coats.
Egg white
Helps clarify the syrup by binding impurities, which rise as scum to be skimmed off.
Lemons
Add acidity that helps keep the sugar syrup from crystallizing.

The step that matters

Skim off the scum after boiling the syrup. Egg white clarifies the syrup as it heats, and impurities rise to the surface as scum. Leaving them in can make the syrup cloudy and affect the finished coating.

Swap the chestnut

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

  1. Pistachiofits about as well
  2. Milletfits about as well
  3. Almondfits about as well
  4. Chestnutthe original

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