White Fondant

Ingredients

Directions

Make the syrup

  1. Combine sugar, hot water, and cream of tartar in a smooth granite saucepan.

  2. Stir the mixture and heat gradually to boiling point.

  3. Boil without stirring until the syrup reaches 238°F (soft ball stage).

  4. Wash off any sugar adhering to the sides of the saucepan with a hand dipped in cold water.

Work the fondant

  1. Pour the syrup slowly onto a slightly oiled marble slab.

  2. Let it cool for a few minutes.

  3. Scrape the syrup to one end of the marble.

  4. Work the fondant with a wooden spatula until it becomes white and creamy.

  5. Knead with your hands until perfectly smooth.

  6. Transfer to a bowl and cover with oiled paper to exclude air.

What each ingredient does

Sugar
Forms the sweet syrup that cools and sets into the fine, smooth crystal structure of fondant.
Cream of tartar
Acid that helps prevent large sugar crystals from forming, keeping the fondant smooth.

The step that matters

Boil without stirring until the syrup reaches 238°F. Stirring during boiling can trigger premature crystallization, leading to grainy fondant. Sugar adhering to the pan sides can also seed crystals, so washing them down with cold water helps keep the texture smooth.
