In this guide, Candy Making Temperatures from Soft Ball to Hard Crack, we’ll walk you through the different stages, share tips for achieving the perfect texture, and troubleshoot common candy-making challenges. Whether you’re creating holiday favorites or experimenting with new recipes, mastering these candy-making temperatures will ensure sweet success every time.
Candy making is a time-honored tradition that brings joy during the holidays and throughout the year. Whether you’re crafting chewy caramels, rock candy, or brittle hard candies, understanding candy temperatures is crucial for success.
Why Candy Temperatures Matter
Candy making revolves around the science of sugar solutions. The desired degree of sugar concentration in the mixture of sugar and water determines the texture of the final product.
As the temperature rises, the candy syrup passes through different stages such as soft-ball stage, firm-ball stage, and hard-crack stage. Using a candy thermometer or the cold water test helps you achieve the correct temperature for your recipe.
Our Homemade English Toffee
I have been making English Toffee for years. Actually it is a recipe that is over 100 years old. Many decades ago, when I first became the person in the family to take over making this recipe, my grandmother gave me $10 to purchase my first candy thermometer.
I’ve since taught anyone who wants to learn how to make the candy. It’s a shame when an old family recipe is lost with someone passes so I am happy to share to keep the recipe going.
It is just delicious. There is a reason we’ve been making this during the Holidays for decades.

The Candy Stages and Their Temperatures
Here’s a breakdown of the candy stages, including their temperatures in degrees F and degrees C, and what each stage is used for.
Tools of the Trade
Candy Thermometer. Invest in a reliable thermometer and regularly test the thermometer’s accuracy by boiling water.
Cold Water Test. If you don’t have a thermometer, use this traditional method. Drop a bit of the sugar mixture into chilled water and observe the texture.
How to Read a Candy Thermometer Accurately
Check Calibration Before Use
Always test your thermometer by placing it in boiling water. At sea level, water boils at 212°F (100°C). If your thermometer reads higher or lower, note the difference and adjust your target temperatures accordingly.
Attach the Thermometer Properly
Clip the thermometer to the side of the pan with the tip submerged in the sugar mixture but not touching the bottom. If it touches the bottom, you’ll get a reading that’s too high because it’s measuring the heat of the pan, not the candy.
Take Readings at Eye Level
Candy thermometers often have a column of liquid or digital display. Make sure to read it at eye level to avoid parallax errors, which can happen when looking at it from an angle.
Monitor Consistently
Keep an eye on the temperature as it rises to avoid missing the transition to the next candy stage. Sugar heats up quickly as it reaches higher temperatures.
Don’t Rely on the Thermometer Alone
Use the cold water test as a backup if you’re unsure. This method involves dropping a small amount of the sugar syrup into chilled water to test its consistency.
Do You Need a Special Candy Thermometer?
Yes, a candy thermometer is designed specifically for high-temperature readings required in candy-making. Here’s how it differs from other thermometers.
Candy Thermometer
- Measures temperatures from about 100°F to 400°F (38°C to 204°C), perfect for candy-making stages.
- Often includes marked stages (e.g., soft ball, hard crack) for easy reference.
- Typically designed with a clip to attach to the side of the pan, keeping your hands free and ensuring accurate placement.
Meat Thermometer
- Measures lower temperature ranges, usually up to 200°F–220°F (93°C–104°C).
- Designed for shorter cooking times and thicker foods like roasts, not for prolonged high-heat tasks like cooking sugar.
Instant-Read Thermometer
- Fast and versatile, but it may not handle the sustained high heat of candy making and doesn’t clip to the pan.
Recommendation. A dedicated candy thermometer is highly recommended for candy recipes, as it’s specifically built for the task. However, an instant-read thermometer can be a good backup, provided it can handle the high temperatures.
How to Do the Cold Water Test
- Prepare a Bowl of Ice Water
- Fill a bowl with ice water to ensure it’s cold enough for the test.
- Drop a small amount of the sugar mixture into the water using a spoon or spatula.
Observe and Test the Candy
Once the candy cools in the water, remove it and check its texture and appearance. The texture will change depending on the stage of the sugar syrup.
The Candy Stages and Their Temperatures
Here’s a breakdown of the candy stages, including their temperatures in degrees F and degrees C, and what each stage is used for.
Candy Stages and What to Expect
Thread Stage. 223°F–234°F. Syrup forms long, thin threads that dissolve when pressed. Use for syrups and glazes.
Soft-Ball Stage. 235°F–240°F.Syrup forms a soft, pliable ball that flattens when pressed. Use for fudge and caramels.
Firm-Ball Stage. 245°F–250°F.Syrup forms a firm ball that holds its shape but is still pliable. Use for nougat and marshmallows.
Hard-Ball Stage. 250°F–265°F. Syrup forms a harder ball that holds its shape and feels firm but not brittle. Use for rock candy and divinity.
Soft-Crack Stage. 270°F–290°F. Syrup forms brittle threads that bend slightly before breaking. Use for taffy and butterscotch.
Hard-Crack Stage. 300°F–310°F. Syrup forms hard, brittle threads that crack easily and do not bend. Use for lollipops and brittle.
Tips for Using the Cold Water Test
Consistency Over Color. While the color may give a clue (e.g., dark amber for caramel), always rely on the texture during the test.
Work Quickly. Sugar syrup hardens fast, so check the candy immediately after dropping it into the cold water.
Test Often. As the temperature rises, the sugar solution moves quickly through the different stages, so test every minute or two once you’re close to the target range.
Light Caramels vs Dark Caramels
The color and flavor of caramels depend on how far you take the sugar mixture in the cooking process. Both light caramels and dark caramels have their own unique qualities, uses, and temperature ranges. Here’s a breakdown.
Light Caramels
Temperature Range. 320°F–330°F
Appearance. A pale golden or amber color.
Flavor and uses. Milder, with a buttery, sweet, and slightly nutty flavor. Ideal for softer caramel sauces or candies like chewy caramels.
Works well in recipes where the caramel flavor needs to be subtle, such as crème caramel or toffee coatings for apples.
Tips for Achieving Light Caramels
Watch the sugar closely as it reaches this temperature, as the caramelization process happens quickly.
Remove the sugar mixture from the heat as soon as the light golden color is achieved to prevent it from darkening further.
Dark Caramels
Temperature Range. 340°F–350°F
Appearance. A deeper amber to dark brown color.
Flavor and uses. Richer, with a bold, bittersweet, and more complex flavor profile due to advanced caramelization. Perfect for robust caramel sauces (e.g., for coffee drinks or over desserts like flan).
Used in candies like pralines, caramelized sugar shards, or as a base for savory dishes like caramel-glazed meats.
Tips for Achieving Dark Caramels
Allow the sugar to cook slightly longer to deepen its color and flavor, but be vigilant to avoid burning.
Remove the sugar from heat immediately as it reaches the desired dark amber color, as it can scorch quickly after 350°F.
General Caramel-Making Tips
Use a Heavy-Bottomed Pan. This helps distribute heat evenly and prevents scorching.
Don’t Stir Once Sugar Melts. Stirring can cause sugar crystals to form. Instead, gently swirl the pan.
Keep a Close Eye. Caramel goes from perfect to burnt in seconds, especially at higher temperatures.
Be Prepared. Have your other ingredients (e.g., butter, cream) ready to add, as caramel can harden quickly once off the heat.
Safety First. Hot sugar is extremely dangerous. Handle with care and avoid tasting until it cools.
Candy Making Tips for Success
Adjust for High Altitudes
The boiling point of water decreases at higher altitudes, which means your candy will cook faster. For every 1,000 feet above sea level, reduce the target temperature by 2°F.
Mind the Weather
Humid days can add moisture to your candy, making it harder to achieve the desired texture. For best results, make candy on dry days.
Monitor Sugar Syrup
Avoid stirring the hot syrup too much during the cooking process to prevent the formation of sugar crystals.
Cooling and Storage
Allow candy to cool on a white plate or parchment paper at room temperature. Store it in an airtight container to maintain its texture.
Why did my candy turn out sticky or grainy?
This is likely the result of sugar crystals forming on the sides of the pan. Use a damp brush to clean the sides or cover the pan briefly to allow steam to dissolve the crystals.
I use a bamboo spoon or wooden spoon when making my candy. That way, you can leave the spoon in the hot candy mixture as it heats without burning your hand. Use the spoon to scrap the sides of the pan as needed. Don’t remove the spoon during the cooking process as it will cause crystallization.
What’s the best way to test the temperature of my candy?
Use a candy thermometer for precision or the cold water test for a quick check.
Can I use alternative sweeteners like brown sugar or corn syrup?
Yes, but note that they may affect the texture and color. For example, corn syrup can help prevent crystallization.
My candy isn’t setting properly.
- Cause. The temperature of the batch was too low, leaving too much moisture in the candy.
- Solution. Double-check the thermometer’s accuracy before starting. Cook to the specified temperature.
My candy turned dark or burned.
- Cause. The temperature of your candy went too high, or the heat wasn’t evenly distributed.
- Solution. Use medium to high heat and a heavy-bottomed pan to maintain even cooking.
How do I adjust for higher elevations?
For every 1,000 feet of elevation, reduce the target temperature by 2°F. For example, at 5,000 feet, reduce by 10°F.
The candy tastes off.
- Cause. Overheating can lead to a burnt or overly caramelized flavor.
- Solution. Monitor the highest temperature closely and avoid cooking sugar beyond the required stage.
Tips for a Smooth Candy-Making Process
- Prepare in Advance
- Gather all tools and ingredients before starting, including a candy thermometer, cold water, and parchment paper.
- Test Your Thermometer
- Before you begin, test your thermometer by boiling water (should read 212°F at sea level).
- Cool Down Candy Properly
- Pour the sugar mixture onto a prepared surface to cool evenly. Use a fan on humid days to help candy set faster.
- Clean Up Made Easy
- Fill your pan with water and bring it to a boil to dissolve leftover sugar before washing.
