Sugar Temperature
Drop a teaspoonful of syrup into a jug of iced water and allow to cool:
thread = 220-230F
The syrup forms threads that won’t make a ball.
Soft ball = 240/243F
The syrup makes a ball that doesn’t hold shape.
hard ball (122C/252F) = 250-260F
What it says!
hard crack (160C/320F) 130C/266F = 285-299F
The syrup makes strands that break.
