Lemon Drops

Ingredients

Directions

  1. Pour enough lemon juice over the powdered sugar to dissolve it.

  2. Boil the mixture until it reaches a thick syrup consistency and appears brittle when dropped in cold water.

  3. Drop the syrup onto buttered plates in small drops. Set aside to cool and harden.

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

What each ingredient does

Powdered sugar
Provides the sweetness and, once boiled into syrup, the mass that sets hard as it cools.
Lemon juice
Dissolves the sugar and adds sharp acidity that balances the sweetness.

The step that matters

Boiling the syrup to the right stage. Sugar syrup hardens into brittle candy only when enough water has boiled off. Stop too early and the drops stay soft or sticky; cook too long and they become bitter and scorched.

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.

“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
