Interactive Candy Temperature Chart

Thread to hard crack — slide the thermometer and see what each stage makes.

Ride the thermometer through the sugar stages

Slide the syrup temperature; the stage, its cold-water behavior, and its classic candies follow.

Candy stages are concentrations wearing temperature as a name: as water boils away, the syrup climbs the scale, and a few degrees separate fudge from caramel from brittle.

  • Find the stage window for fudge — how wide is it?
  • What changes between soft crack and hard crack, in water and in candy?

Candy stages are concentrations wearing temperature as a name: as water boils away, the syrup climbs from thread (106 °C) through soft ball (fudge), hard ball (marshmallow), and on to hard crack (149 °C) for brittle and lollipops.

Slide to your recipe's target and read the stage, its cold-water behavior, and its classic uses — and note how narrow some windows are, which is why candy demands a thermometer.

What temperature is soft ball stage?

112–116 °C — the fudge and fondant zone.

Why did my caramel turn bitter?

Past ~154 °C sugar itself browns fast; a few unattended degrees separate amber from burnt.
