Why won t my marshmallow fudge harden? ›

Fudge Didn't Set

If your fudge turned out super sticky, or it didn't set as it cooled, it probably never got hot enough. This mistake is super easy to avoid if you use a candy thermometer and cook the fudge to the temperature specified in the recipe (usually between 234 and 239°F).

If it doesn't boil, your fudge will end up too mushy, and if it cooks for too long, you'll end up with a dry, crumbly mess. This is why many recipes recommend using a candy thermometer, so you know exactly when to remove your mixture from the heat.

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!

They are not the same. Marshmallow cream is made without gelatin and will not firm up over time. Marshmallows that have been melted down, on the other hand, will firm back up unless you add something to them to help keep them more fluid (like adding butter to make rice krispie treats).

To fix it, you can reheat the fudge mixture over low heat and continue cooking until it reaches the proper temperature. Be sure to use a candy thermometer to monitor the temperature accurately. Alternatively, you can try to salvage chewy fudge by mixing it into ice cream or using it as a topping for desserts.

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.

Fudge usually behaves this way when it's not cooked to a high enough temperature (due to oversight or a faulty candy thermometer). If your fudge is tough, hard, or grainy, then you may have made one of several mistakes: You may have overcooked it, beaten it too long, or neglected to cool it to the proper temperature.

It sounds like your fudge simply wasn't heated enough. Fudge is basically a superconcentrated syrup, and it sets when sugar dissolved in the water (from the butter and milk) comes out of solution as the mixture cools and forms crystals.

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.

Brush the sides of the pan with a wet brush at the beginning of cooking to dissolve sugar crystals stuck to the sides. Never stir the mixture during cooking or sugar could crystallize again. The mixture may seize and become grainy.

Why do you add vanilla to fudge? ›

Vanilla is often added to chocolate candies or other chocolate recipes because it complements and accents the flavor of chocolate.

You may also see it as marshmallow Fluff in recipes, but marshmallow Fluff is actually a specific brand of marshmallow creme. If you do not have access to marshmallow creme, you can melt 14 ounces of marshmallows in the microwave and then add the remaining ingredients.

Fluff can be stored at room temperature. If you don't plan on using your Fluff for a while, refrigeration will extend the shelf life significantly.

One of the easiest ways for marshmallow fluff to get hardened is through the exposure of cool temperatures and air.

You have one option to make it soft, which is you have to put the fudge pieces in a plastic bag along with the paper towel or a bread slice. Secure the bag and leave it overnight, next day you will get a softened fudge.

For perfect fudge, the syrup should form a soft ball that can be picked up, but easily flattened. If the syrup is undercooked, drops of syrup will sink to the bottom of the glass in threads or simply dissolve. If the syrup is overcooked, the ball will be hard and difficult to flatten with your fingers.

The key to getting the perfect marshmallow consistency is in the mixing. As you mix all the hot ingredients together, you inherently add air to the recipe. This air gives your marshmallow its fluff. And as more and more air enters the mix, the gelatin and sugar cool and set.
