Peppermint Candy

Ingredients

Directions

The book gives no oven temperature. The 300°F in the steps was added when the recipe was transcribed, as a starting point.

Make the syrup

  1. In a saucepan, combine sugar and water, and stir until the sugar dissolves.

  2. Add butter and vinegar, then bring to a boil without stirring.

Cook and flavour

  1. Cook until the mixture reaches the hard crack stage (300°F or 150°C).

  2. Remove from heat and add peppermint oil or essence.

Set and break

  1. Pour onto a greased surface and let cool before breaking into pieces.

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

What each ingredient does

Sugar
Forms the candy's glassy, hard structure as the syrup cooks and cools.
Water
Dissolves the sugar so it can cook evenly without crystallising too early.
Vinegar
Acidity helps prevent sugar crystals from forming, keeping the candy smooth.
Butter
Adds a little fat that softens the candy's texture and gives a richer finish.

The step that matters

Cook to the hard crack stage without stirring. Stirring after the sugar boils can trigger crystallisation, making the candy grainy. Cooking to 300°F (150°C) drives off enough water for the candy to set hard and brittle rather than sticky.

Swap the peppermint

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

  1. Cinnamonfits better
  2. Tarragonfits better
  3. Peppermintthe original
  4. Allspicefits about as well

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