Science of Candy: What's Special About Fudge? | Exploratorium? ›

Fudge is one of the rare exceptions to the rule that sugar crystals are not desirable in candy. Tiny microcrystals in fudge are what give it its firm texture. The crystals are small enough, however, that they don't feel grainy on your tongue, but smooth.

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.

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.

Characterised by its smooth, creamy texture and decadent flavour, fudge is typically made from a mixture of sugar, butter, and milk or cream. The ingredients are heated to the soft-ball stage, around 235-245°F (113-118°C), and then beaten while cooling, which gives fudge its characteristic smooth and dense texture.

fudge, creamy candy made with butter, sugar, milk, and usually chocolate, cooked together and beaten to a soft, smooth texture.

Although fudge often contains chocolate, fudge is not the same as chocolate. Chocolate is a mix of cocoa solids, cocoa butter and sometimes sugar and other flavorings and is hard and brittle. Fudge is a mixture of sugar, dairy and flavorings that is cooked and cooled to form a smooth, semi-soft confection.

to avoid making a decision or giving a clear answer about something: fudge the issue The government continues to fudge the issue by refusing to give exact figures.

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.

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.

Chewy fudge results from the excessive moisture present in the mixture, which means the fudge was not cooked to the right temperature and could not be cooked enough to release the moisture. However, take care not to overcook fudge because it will take away the moisture and leave you with hard, chewy candy.

Why is fudge so tasty? ›

Between its deeply rich flavor and its silky texture, fudge makes a brilliant treat to pair with coffee. The sweet and bitter flavors complement one another perfectly, making for an unstoppable combination.

Fudge can also include other ingredients such as nuts, dried fruits, or marshmallows for added flavor and texture. The key to making great fudge is achieving the right balance of sweetness and creaminess while still allowing the chocolate flavor to shine through.

That appetite for fudge dates back more than a century. Food historian Joyce White says fudge is based on a recipe for chocolate caramels, which was very similar. "What probably happened is that there was someone in Baltimore, messed it up, or 'fadged' it," she said. "Fadge is a word that means you messed up.

Culinary legend has it that fudge was invented in America. On Valentine's Day, 1886, a confectioner and chocolate maker in Baltimore, Maryland "fudged" a batch of French caramels. The delicious result? The very first batch of "fudge" ever.

Unlike other desserts that date back thousands of years, fudge is a relatively new dessert that was created in the late 1800s. Today, fudge can be made with just chocolate and condensed milk at its simplest form. Chocolatiers often make fudge in its original form of chocolate, cream, butter, and sugar.

If the sugar crystals are not properly dissolved before cooling, they can create a gritty texture. To avoid this, ensure that you stir the fudge mixture consistently and remove any sugar crystals that form on the sides of the pan using a wet pastry brush.

Tiny microcrystals in fudge are what give it its firm texture. The crystals are small enough, however, that they don't feel grainy on your tongue, but smooth. While you ultimately want crystals to form, it's important that they don't form too early.

Small sugar crystals give you a smooth melt in the mouth texture. The secret to smooth fudge is to let the sugar syrup cool undisturbed until it reaches about 110°F and then beat it until no longer shiny.

Beating the mixture encourages the formation of small sugar crystals, which leads to the crumbly texture. The crystals may not be noticeable in themselves but the fudge mixture will thicken and turn from shiny to matte in appearance.

The addition of egg whites and gelatin will coat the sugar crystals and keep them small. This results in creamy fudge. Shhh! It's a Fudgy Secret!
