Chestnuts in Syrup, and Glazed

Ingredients

Directions

Prepare the chestnuts

  1. Remove the outer skin from the chestnuts carefully.

  2. Blanch the chestnuts in boiling water until you can pierce them easily with a needle.

  3. Remove the inner skin and drop each nut into warm acidulated water.

Make the syrup and cook the chestnuts

  1. Prepare a plain syrup and drain the nuts before adding them to the syrup.

  2. Simmer the nuts gently in the syrup until tender and the syrup thickens.

  3. Bottle and cork the chestnuts for storage.

Glaze and serve

  1. To serve, drain the chestnuts and boil some syrup to the crack stage.

  2. Work the syrup against the sides of the pan with a wooden spoon until it whitens.

  3. Dip each chestnut into the syrup with a skewer and dry them in the oven on trays.

Sugar and lemon barely smell alike, yet cooks put them together in 53,532 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Chestnuts
Form the main body of the dish and set its tender, starchy texture when cooked in syrup.
Sugar
Sweetens the dish and, as syrup, builds the glossy coating on the nuts.
Lemon juice or vinegar
Acidulates the water, helping keep the peeled chestnuts pale rather than darkening.

The step that matters

Working the syrup until it whitens. Syrup boiled to the crack stage and then stirred against the pan sides turns opaque and crystallises into a dry, sugary coating. Stirring too little leaves the glaze wet and sticky, while overworking can make it grainy.

Swap the lemon

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

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