Ingredients

Directions

Make the creams

  1. For dipping cream, mix sugar with a small amount of glucose or cream of tartar.

  2. For center creams, add 4 ounces of glucose to each pound of sugar and boil slightly higher.

Warm, color and flavor

  1. Warm the dipping cream in a double kettle, stirring gently until soft enough to cover fruits or nut pastes.

  2. Color and flavor the creams as desired.

What each ingredient does

Sugar
Forms the sweet base that sets into the fine crystals of fondant.
Glucose
Interferes with sugar crystal growth, keeping the fondant smooth and soft rather than grainy.

The step that matters

Boiling the center creams. The boiling temperature controls how much water remains in the sugar syrup. Boiling slightly higher leaves less water, so the cream sets firmer; boiling too little leaves it soft and sticky.
