FAQs

What is the difference between soft and hard fudge? ›

The difference comes in temperature, which ranges from 113C from Behan, which gives a very soft, almost fondant-like result, to Aikens's 121C, which is brittle and chewy, more like a hard caramel than a fudge.

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.

Never stir the mixture during cooking or sugar could crystallize again. The mixture may seize and become grainy. Use a candy thermometer or conduct a cold water test to check if the fudge is done.

Without stirring or agitating the pot, allow the fudge to cool to 130°F (54°C)—or even lower! Harold McGee says that “candy texture is affected by the syrup temperature at which crystallization begins,” and this is the temperature where the seeds can form correctly.

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.

Humidity can cause fudge to boil over in the pan or stay soft when set, so try to avoid working on humid days if at all possible. If waiting for a less humid day isn't feasible, you'll need to boil your fudge at a slightly higher temperature than usual — or just order some delicious fudge from Wockenfuss!

Once a seed crystal forms, it grows bigger and bigger as the fudge cools. A lot of big crystals in fudge makes it grainy. By letting the fudge cool without stirring, you avoid creating seed crystals.

Too cooked

The result is hard and brittle fudge. To save the fudge, put it in a saucepan with 45 to 60 ml (3 or 4 tbsp.) of 35% cream and bring to a boil, stirring until the sugar is completely melted. Then let it boil without stirring until the thermometer reaches 114 to 115 °C (237 to 239 °F).

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.

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.

Can you fix fudge that didn't harden? ›

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.

Perhaps you heard your grandmother complain that “you can never make fudge when it's raining.” No mythical urban legend here. High humidity alters the cooking properties of sugar. Fudge can take three times as long to set up, if at all. Sugary meringue absorbs humidity.

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).

Overcooking or Undercooking:Solution: Cooking the fudge for too long or too short a time can affect its texture. Follow the recipe instructions closely and use a timer to avoid overcooking.

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 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.

If your fudge is soft or runny, it probably didn't come up to a high enough temperature while it was cooking. Put it back into the saucepan and add 1–2 US tbsp (15–30 ml) of 35% fat whipping cream. Stir the fudge as it heats, but only until the sugar in the chocolate is completely melted again.
