Vanilla Sugar Candy

Ingredients

Directions

Make the candy

  1. Combine sugar, water, vinegar, butter, and glycerine in a pot.

  2. Boil without stirring for 20 to 30 minutes until it forms a crisp ball when dropped into water.

  3. Just before pouring onto platters to cool, add baking soda or cream of tartar.

Finish and shape

  1. Pour the mixture onto platters and drizzle the vanilla over the top.

  2. Once cooled, pull the candy into sticks or cut into desired shapes with shears.

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

What each ingredient does

Granulated sugar
Forms the candy's sweet, glassy structure as it cooks and hardens.
Vinegar
Acidity helps keep the sugar from crystallizing into a grainy texture.
Glycerine
Keeps the candy softer and more pliable by discouraging sugar crystals from forming.
Baking soda or cream of tartar
Added late, it lightens the candy's texture and aids in creating an airy, brittle result.

The step that matters

Boil without stirring until a crisp ball forms. Stirring can trigger sugar crystallization, making the candy grainy. Boiling to the hard-crack stage sets the candy firm once it cools, so the test must be accurate.

Swap the vanilla

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

  1. Vanillathe original
  2. Strawberryfits about as well
  3. Raspberryfits less well
  4. Apricotfits less well

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