Whats Going On? 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 good fudge? ›
Tips for Making Fudge
- Monitor the Temperature with a Candy Thermometer. If you end up with soft fudge that turns into a puddle in your hands or hard fudge that is a bit reminiscent of a crunchy candy, improper temperature is likely to blame. ...
- Avoid Stirring Once the Mixture Comes to a Simmer. ...
- Beat Thoroughly.
How does fudge relate to chemistry? ›
The Science of Fudge: How Fudge Is Made
This technique helps prevent sucrose molecules from forming into a large crystal. Once cooled to 122° F, the syrup is stirred and scraped, forming many crystals at once. Continued stirring helps the sugar molecules spread among and bind to the crystal seeds.
What is the principle of fudge? ›
Principles of quality 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 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.
What makes fudge hard or soft? ›
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.
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.
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!
What happens if you stir fudge too early? ›
Sugar Crystals Formed
It's important to beat the fudge ingredients to develop the right texture, but you won't get smooth, creamy fudge if you beat it when it's too hot. Beating fudge when it's still over heat creates sugar crystals, aka the grittiness you feel in the fudge.
What temperature should fudge be cooked at? ›
Stir the ingredients to dissolve the sugar until the mixture comes to a boil. If your recipe uses milk, stirring will keep the mixture from curdling. But once it reaches about 236–238 degrees F/113–114 degrees C (the "soft-ball" stage), do not stir it or even shake the pan.
Candy that isn't cooked long enough will end up too soft; overcooking makes fudge crumbly or hard. High-quality fudge has many small crystals. If the process of crystallization begins too early, fewer crystals form and they become much larger.
Why did my fudge turn out like taffy? ›
If the fudge is very soft and slightly chewy then it is possible that it did not quite cook to soft ball stage and next time the mixture should be cooked to a slightly higher temperature (soft ball is 112-116c/235-240F and a sugar or candy thermometer can help).
What is the science behind fudge? ›
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 is the ball method fudge? ›
According to most recipes, the ingredients of fudge are cooked to what is termed in kitchen parlance the soft ball stage, that point between 234 and 240 °F (112 and 115 °C) at which a small ball of the candy dropped in ice water neither disintegrates nor flattens when picked up with the fingers.
What is the difference between English fudge and American fudge? ›
Turns out that the two are not quite the same, but they're still equally delicious. Denser and sometimes a bit more crumbly than its American counterpart, British fudge comes in dozens of flavors, and is frequently found in gift shops and at outdoor markets and street fairs.
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 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.
