What is the secret to good fudge? ›

You have to control two temperatures to make successful fudge: the cooking temperature AND the temperature at which the mixture cools before stirring to make it crystallize. Confectionery experiments have shown that the ideal cooking temperature for fudge is around 114 to 115 °C (237 to 239 °F).

The most common culprit behind unset fudge is inaccurate temperature control. If the sugar mixture hasn't reached the correct temperature, your fudge won't set. Ensure you use a reliable candy thermometer and follow temperature guidelines meticulously to achieve the desired consistency.

By cooling the fudge prior to agitation (like in the recipes included in this article), on the other hand, you'll get much smaller, finer sugar crystals and a finished fudge with a smooth, creamy texture. Cool the mixture until it reads 120° F on the thermometer—no stirring. This can take 1 to 1/2 hours.

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!

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. Conversely, cook it too long and fudge won't contain enough water, making it hard with a dry, crumbly texture.

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. Why? Stirring at the wrong time causes the sugar to form large crystals. That's the "graininess" that inexperienced fudge-makers complain about.

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. That's why we recommend investing in a sugar thermometer. Another reason your Fudge is not setting is that the ratio of liquid to sugar is too high.

A lot of big crystals in fudge makes it grainy. By letting the fudge cool without stirring, you avoid creating seed crystals. Stirring would help sucrose molecules "find" one another and start forming crystals.

Options for what you can do with your unset fudge:

OPTION 1) Depending on how runny it is, you can either use it as a frosting for cakes, or a sauce for ice-cream. OPTION 2) Freeze it overnight. Cut it into squares. Cover each square thickly in melted chocolate, ensuring no part of the fudge is exposed.

Coarse grainy fudge results when large crystals are allowed to form. Butter is added in the final stages to add flavor and smoothness and inhibit large crystal formation. Use unsalted butter so you can add a small amount of salt (¼ teaspoon per stick of butter) to the sugar/liquid mixture.

“Too much cream of tartar will impart a metallic, tin-like taste,” Molly warns.

For this reason, white vinegar is the go-to vinegar for substituting cream of tartar, since it has the least distinct flavor. Lemon juice: If you'd rather not use vinegar, fresh lemon juice is a good option.

The key to successful, nongrainy fudge is in the cooling, not the cooking. The recipe calls for heating the ingredients to the soft-ball stage, or 234° F, then allowing it to cool undisturbed to approximately 110° F.

Dan Ariely, a behavioral economics professor at Duke University, describes this situation using the “fudge factor theory.” In simple terms, the fudge factor theory states that humans have a desire to secure the benefits of cheating but simultaneously view ourselves as honest people (Ariely).

High-quality fudge tastes smooth and creamy because it contains small sugar crystals. It has a deep brown color and a satiny sheen. Poor-quality fudge tastes grainy because it contains large sugar crystals.

Too Soft or Too Hard Fudge

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.
