What each ingredient does

Sugar
Provides sweetness and, once cooked and worked, forms fine crystals that give fondant its smooth body.
Water
Dissolves the sugar so it can be boiled to a controlled concentration.
Acid
Interferes with large sugar crystals, helping the fondant stay smooth rather than grainy.

The step that matters

Boil to the 'Little Ball' stage. The syrup's final concentration sets the fondant's firmness. Stopping too early leaves it soft and runny, while boiling too long makes it hard and brittle once worked. Cooling and working it afterwards then turns it into a smooth, pliable paste.
