What each ingredient does

Cane sugar
Forms the crystal-free glassy structure of the spun threads as the syrup cools and hardens.
Cream of tartar
Acid that helps prevent the sugar from recrystallizing, keeping the syrup smooth and clear.

The step that matters

Boil without stirring until it reaches the crack stage. Stirring can trigger sugar crystallization, which makes the syrup grainy. The syrup must reach the crack stage, where it is concentrated enough to set hard and form strong threads as it cools.
