Ice Cream Candy

Ingredients

Directions

Make the candy

  1. Boil the sugar, butter, water, and lemon peel together until it becomes crisp when dropped into cold water.

  2. Set aside until boiling ceases, then stir in the lemon juice.

  3. Butter a dish and pour in the mixture to about 1 inch thick.

Finish and shape

  1. Once cool, remove the lemon peel, pull the candy until white, and shape as desired.

  2. If you don't have lemon, use 2 tablespoons of vinegar and 2 teaspoons of extract instead.

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

What each ingredient does

Moist white coffee sugar
Forms the candy base and sets into a brittle, sweet mass as it cools.
Butter
Adds fat that softens the texture and gives a richer mouthfeel.
Lemon juice
Adds acidity and bright lemon flavour to the candy.

The step that matters

Boil until crisp in cold water. Sugar must reach the hard-crack stage to set brittle rather than sticky. Stopping too early leaves a soft, tacky candy that will not hold its shape.

Swap the lemon

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

  1. Vanillafits better
  2. Figfits better
  3. Bananafits better
  4. Lemonthe original

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