What are the main candy temperature stages?

There are six main stages: thread (230–235 F), soft ball (235–240 F), firm ball (245–250 F), hard ball (250–265 F), soft crack (270–290 F), and hard crack (300–310 F). Each produces a different sugar texture.

Why does temperature matter so much in candy making?

As sugar syrup heats, water evaporates and the sugar concentration rises. Each temperature range causes sugar molecules to behave differently when cooled, producing distinct textures from syrupy to glass-like.

What candies use the soft ball stage?

The soft ball stage (235–240 F / 112–115 C) is used for fudge, pralines, and fondant. Sugar cooked to this stage forms a soft, pliable ball when dropped into cold water.

What is the hard crack stage used for?

Hard crack (300–310 F / 149–154 C) is used for lollipops, hard candy, peanut brittle, and toffee. At this stage sugar is very brittle and snaps cleanly when cooled.

Can I use this guide without a candy thermometer?

Yes — each stage also has a cold water test description. You can drop a small amount of hot syrup into cold water and observe the texture to determine the stage, though a thermometer gives more reliable results.

Does altitude affect candy temperatures?

Yes. At higher altitudes water boils at lower temperatures, so subtract about 2 F (1 C) for every 1,000 feet above sea level from the target temperatures shown in this guide.

Summary

Candy making depends on precise sugar temperatures. Each stage — from thread through soft ball, firm ball, hard ball, soft crack, to hard crack — produces a different texture and is used for different confections. This guide lists every stage with its temperature range in both Fahrenheit and Celsius, plus a lookup tool so you can type in any temperature and instantly see which stage it falls in.
