White Sugar Candy

Ingredients

Directions

Make the syrup

  1. Pour boiling water over the sugar and stir until dissolved.

  2. Set the mixture on the fire and boil briskly without burning.

  3. Do not stir while boiling.

  4. Test the candy by dipping a little in cold water; it is done when hard.

Finish and pull

  1. Boil the butter and vinegar together in a tin cup until hot.

  2. Pour the hot mixture into the candy.

  3. Flavor with vanilla or lemon.

  4. Carefully pour the candy onto buttered plates.

  5. When cool, pull until white.

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

What each ingredient does

White sugar
Forms the bulk of the candy and sets firm as the syrup cooks down.
Vinegar
Acidity helps prevent the sugar from crystallizing into a grainy texture.
Butter
Adds fat that softens the candy's texture and gives it a richer mouthfeel.

The step that matters

Boil briskly without stirring. Stirring while sugar syrup boils can trigger crystallization, leaving the candy grainy. Keeping the pot undisturbed lets the syrup reach the right concentration smoothly, and the burn warning matters because scorched sugar turns bitter.

Swap the vanilla

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

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