Why do I add corn syrup?
Corn syrup acts as an "interfering agent" in this and many other candy recipes. It contains long chains of glucose molecules that tend to keep the sucrose molecules in the candy syrup from crystallizing. In fudge, the addition of "interfering agents" can be a double-edged sword: you want crystals to form, but not until the cooked mixture has cooled down to a certain degree. Why do I add vanilla?
Vanilla is often added to chocolate candies or other chocolate recipes because it complements and accents the flavor of chocolate. Why do I need to stop stirring after the syrup begins to boil?
At this point, you have dissolved the crystal structure of the sugar. Stirring or other agitation is one of the many factors that can encourage the fructose and glucose molecules in your syrup to rejoin and form sucrosecrystals of table sugar. Why do I wash down the sides of the pan?
The sugar crystals are dissolved at this point in the process. But a single seed crystal of sugar clinging to the side of the pan might fall in and encourage recrystallization. Why does the fudge need to cool for such a long time?
The key to a smooth and creamy texture is a fudge that's full of thousands of tiny sugar crystals. Heating the syrup to a high temperature and then allowing it to cool, undisturbed, produces a supersaturated solutionthis means that the solution contains more sugar molecules than would normally be possible at room temperature. A supersaturated solution is highly unstable, and any agitation will cause crystallization to occur throughout the solution. If fudge is stirred while it's still hot, fewer crystals form, and they grow larger as the syrup cools, resulting in a coarse, grainy candy. Why is it so important to keep stirring until the fudge "sets"?
Stirring helps control the size of the sugar crystals that formit keeps them from growing too large, which would produce gritty fudge. close this window |
FAQs
Confectionery experiments have shown that the ideal cooking temperature for fudge is around 114 to 115 °C (237 to 239 °F). The cooking is intended to evaporate a part of the liquid and concentrate the sugar. The temperature of the cream/sugar mixture (called syrup) rises as water evaporates.
What is the secret to perfect fudge? ›
The key to creamy, luscious fudge is controlling crystal formation. If the sucrose (table sugar) crystals are small, the fudge will feel creamy and smooth on your tongue. But if the crystals are large, the fudge develops a crumbly, dry, or even coarse texture.
What is the process of making fudge? ›
Commercial fudges are generally prepared by mixing milk, corn syrup (glucose), sugar, fat, a little salt, and suitable flavoring matter such as chocolate; cooking the resulting mixture to a temperature of about 235 F. to 245 F., while agitating the mix; cooling the mix to a temperature between 90 F.
What happens if you cook fudge too long? ›
If there is too much evaporation, when the cooking time is too long, there will not be enough water left in the fudge and it will be too hard. Conversely, if the cooking time is too brief and there is not enough evaporation, too much water will remain and the fudge will be too soft.
What is the secret to non-grainy fudge? ›
A lot of big crystals in fudge makes it grainy. By letting the fudge cool without stirring, you avoid creating seed crystals.
How long do you boil fudge to get to soft ball stage? ›
How long does it take to make fudge:
- about 18 min to reach boiling.
- about 40 minutes to reach soft ball stage.
- 60 minutes to cool.
- 28 minutes to beat in a KitchenAid (your time for this may vary)
- 4 hours to set.
7 Common Mistakes to Avoid for Candy Shop-Worthy Fudge and Caramels
- Using the Wrong Pan. All candy and confections start by melting sugar. ...
- Stirring the Sugar. ...
- Not Using a Candy Thermometer. ...
- Leaving Out the Parchment Paper Lining. ...
- Skipping the Cooking Spray. ...
- Scraping the Pot. ...
- Using a Cold Knife to Slice.
Don't stir!
Once the fudge reaches soft-ball stage on the candy thermometer, remove from the heat and let the temperature drop to 110°F. Keep that spoon or spatula out of the pot until this happens. If you stir too early in the process, you'll make the sugar crystals too big and end up with grainy fudge.
What does cream of tartar do in fudge? ›
Cream of tartar is used in caramel sauces and fudge to help prevent the sugar from crystallizing while cooking. It also prevents cooling sugars from forming brittle crystals, this is why it's the secret ingredient in snickerdoodles!
Is evaporated milk or condensed milk better for fudge? ›
Evaporated milk doesn't have sugar added. The sweetened condended milk is needed as no extra sugar is added to the fudge. If evaporated milk were used then the fudge would not be sweet enough and also would still be too soft unless the fudge is frozen.
The amount of time you cook fudge directly affects its firmness. Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.
What is the principle of fudge? ›
Heating the sugar and milk mixture allows the milk to dissolve more and more sugar, and by the time the mixture is boiling, all the sugar is dissolved. The general principle is that at a particular temperature, a given solvent (in this case, milk) can dissolve only so much of a particular solute (sugar).
How to know when fudge is done? ›
To test the boiling mixture for doneness, drop a bit of it into a bowl of cold water. If it forms a ball that is soft enough to flatten between your fingers, the mixture is ready for cooling. When the fudge cools to 110 degrees F/43 degrees C, beat the mixture vigorously with a wooden spoon until it's no longer glossy.
Can I reboil fudge that didn't set? ›
How can you fix soft fudge? Put it in a microwave safe bowl that is large enough that it won't boil over. Reheat it to the boiling point and cook for about 3 more minutes. Then you can beat some powdered sugar into it if this doesn't make it set.
Why did my homemade fudge not harden? ›
Why has my Fudge not set? The main reason is that your Fudge has not reached the optimum temperature. If your mixture only reaches 110 or 112 degrees Celsius it will always be soft.
How does fudge relate to chemistry? ›
When making fudge, heat and acid work together to convert sucrose – basic white sugar – into its two components, glucose and fructose. When these sugars are present, they prevent sucrose from turning into big sugar crystals.
What causes fudge to set? ›
The amount of time you cook fudge directly affects its firmness. Too little time and the water won't evaporate, causing the fudge to be soft. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.
What is fudge technically? ›
Fudge is a dense, rich confection typically made with sugar, milk or cream, butter and chocolate or other flavorings. The base for fudge is boiled until it reaches the soft-ball stage (135 to 140 degrees F), then stirred or beaten as it cools to minimize the formation of sugar crystals.
What is fudge explained? ›
fudge, creamy candy made with butter, sugar, milk, and usually chocolate, cooked together and beaten to a soft, smooth texture. Fudge may be thought of as having a consistency harder than that of fondant and softer than that of hard chocolate.
