Candy — Bonbon— Conserve

Ingredients

Directions

  1. Add butter to the sugar when it starts boiling to prevent it from rising over the pan.

  2. Mix cream of tartar with sugar and water.

  3. Bring the mixture to a boil, ensuring it doesn't grain.

  4. If it starts to grain, move it to a cooler spot and handle it minimally.

  5. If overcooked, add a little water and boil again.

What each ingredient does

Sugar
Forms the sweet base of the syrup and sets its texture as it cooks.
Cream of tartar
Its acidity helps keep sugar from crystallizing into a grainy texture.
Butter
Its fat reduces foaming so the boiling mixture does not rise over the pan.

The step that matters

Bring the mixture to a boil without graining. Sugar syrup turns grainy when sugar crystals form during boiling. Handling it gently and moving it to a cooler spot if graining starts helps keep it smooth, because agitation and stray crystals can trigger crystallization.
