Crystal Syrup

Ingredients

Directions

Make the syrup

  1. Combine 20 lbs of sugar and 9 quarts of water in a kettle.

  2. Heat and mix until boiling.

  3. Skim off any impurities that rise to the surface.

  4. Cover the kettle and steam for a few minutes.

  5. Remove the cover and wash the sides of the kettle with a wet brush.

  6. If using a syrup gauge, dip a cup into the mixture.

  7. If the gauge shows a weight of 35, remove from heat.

Cool the syrup

  1. Set the kettle in a stable place to cool without agitation.

  2. Once cool, sprinkle the surface with cold water and let it set until the crust dissolves.

Pour and finish

  1. Carefully dip out the syrup and pour it over your goods.

  2. Place a sheet of paper on the syrup's surface in the pans.

  3. When ready to remove, lift the paper to take the crust with it.

  4. If you don't have a syrup gauge, cook the syrup to 228°F.

  5. Then reduce it with water to 220°F.

What each ingredient does

Sugar
Provides the sweetness and the concentrated body of the syrup as it dissolves and cooks.
Water
Dissolves the sugar and is added or cooked off to adjust the syrup's concentration.

The step that matters

Cool the kettle without agitation. Stirring or moving the cooling syrup can trigger sugar crystals to form unevenly, leaving a grainy texture instead of a smooth, clear syrup.
