Vanilla Barley Sugar

Ingredients

Directions

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

Prepare the syrup

  1. Moisten the sugar with water and acetic acid.

  2. Add the essence of vanilla.

  3. Boil the mixture to the crack stage (about 300°F or 150°C).

Set and finish

  1. Pour the hot sugar into a small, deep, oiled pan.

  2. Before it sets, mark the surface into diamond shapes with a knife.

  3. Allow to cool and harden, then snap apart the pieces.

The flavor team

The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

    Shared aroma: beta-damascenone (apple, rose).

Sugar and vanilla barely smell alike, yet cooks put them together in 35,032 recipes: they work on texture and structure more than aroma.

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

What each ingredient does

Fine loaf sugar
Forms the glassy, hard candy structure as it cooks and cools.
Acetic acid
Acidity helps stop the sugar from crystallising, keeping the candy clear and smooth.
Water
Dissolves the sugar so it can be cooked evenly without burning.

The step that matters

Boil to the crack stage. Sugar must reach about 300°F (150°C) so that, once cooled, the water content is low enough for the candy to harden and snap rather than stay sticky. Undercooking leaves it soft; overcooking can scorch it.
