Vanilla Sugar Candy

Ingredients

Directions

The book gives no oven temperature. The 300°F (150°C) in the steps was added when the recipe was transcribed, as a starting point.

Make the candy

  1. In a saucepan, combine vinegar, butter, and glycerine.

  2. Boil without stirring for 20 minutes, or until it reaches 300°F (150°C) when dropped in water.

  3. Just before pouring onto platters to cool, add baking soda and vanilla.

Finish and shape

  1. Pull the candy until it is beautifully white.

  2. Make it into strips and cut with shears.

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

What each ingredient does

Vinegar
Acidifies the sugar syrup, helping it stay smooth and resist crystallizing.
Baking soda
Reacts with the acid to create gas bubbles that lighten the candy and make it opaque.
Butter
Adds fat for a softer bite and richer flavor in the finished candy.
Glycerine
Acts as a humectant that keeps the candy from drying out and becoming brittle.

The step that matters

Boil without stirring to 300°F (150°C). Stirring can trigger sugar crystallization, and stopping at the right temperature sets the candy's hardness. Too low leaves it sticky; too high makes it brittle.

Swap the vanilla

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

  1. Strawberryfits better
  2. Currantfits better
  3. Raspberryfits better
  4. Vanillathe original

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