Soft Crack Stage (270-290°F) — Candy Making Temperature Guide

Soft Crack Stage: 270-290°F (132°C). Syrup separates into hard but pliable threads in cold water that bend before breaking. Used for: Taffy, butterscotch, firm caramel apples. Threads are firm but still bend. Taffy is pulled at this stage while still warm. Be extremely careful — sugar at this temperature causes severe burns. This guide covers everything you need to know about this topic, including common causes, step-by-step solutions, and answers to frequently asked questions.

Here are the key things to understand: Temperature: 270-290°F (132°C+). Test: Syrup separates into hard but pliable threads in cold water that bend before breaking.

Be extremely careful — sugar at this temperature causes severe burns.. Always use a candy thermometer clipped to the side of the pot — do not guess. Understanding these fundamentals will help you diagnose and resolve this issue more effectively.

The most common reasons this occurs include: Candy making depends entirely on precise sugar temperatures. Each stage produces fundamentally different candy textures. Even 5°F too high or low completely changes the result. The cold water test is a reliable backup if your thermometer fails. Identifying the root cause is the first step toward finding the right solution.

To resolve this, follow these recommended steps: Clip a candy thermometer to the pot before starting. Heat sugar syrup until thermometer reads 270-290°F. Cold water test: Syrup separates into hard but pliable threads in cold water that bend before breaking. Threads are firm but still bend. Taffy is pulled at this stage while still warm. Be extremely careful — sugar at this temperature causes severe burns.. Never stir sugar syrup once boiling unless the recipe specifically says to.
