Fondant

Ingredients

Directions

Make the syrup

  1. In a clean copper kettle, combine sugar, water, and glucose.

  2. Place over medium heat and stir with a wooden paddle until it begins to boil.

  3. Use a skimmer to remove any dirt and scum that rises to the top.

  4. Remove from heat and crush any undissolved lumps.

  5. Return to heat, cover with a lid, and steam down the sides of the kettle.

  6. Boil until the temperature reaches 230°F (110°C).

Cool and knead

  1. Pour onto a slab well wet with cold water and let it cool until nearly cold.

  2. Knead into a soft mass with your hands.

  3. Place in an earthen crock and cover with a damp cloth until ready to use.

What each ingredient does

White sugar
Forms the bulk of the fondant and, once cooled and kneaded, sets into a fine-textured, soft mass.
Glucose
Interferes with sugar crystal formation, helping the fondant stay smooth and soft rather than grainy.
Water
Dissolves the sugar so it can be boiled into a syrup before cooling.

The step that matters

Crush any undissolved lumps before reboiling. Undissolved sugar crystals can seed unwanted crystallization as the syrup cools, making the fondant grainy. Crushing them while the syrup is still hot helps everything dissolve evenly before the final boil.
