Key Lime Fudge Recipe (2024)

FAQs

What is the secret to perfect 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).

How do you make Key Lime Fudge? Evaporated milk, sugar and salt are heated together in a saucepan and boiled for 8 minutes. Once that mixture has boiled for several minutes, it'll be piping hot. At that point, you'll pull the pan off the stove and stir in marshmallows, white chocolate, lime zest and lime juice.

My advice to you is to just pour it in a jar, call it something else delicious, and pretend you meant for it to be that way. The nice thing about my “failed” fudge is that it tastes absolutely delicious! A spoonful of the delectable treat will make you want for more.

(Some residents of the Florida Keys and true Key lime pie aficionados will only use Key limes from the Keys.) If you can't find them anywhere, however, you can substitute a combination of regular fresh lime juice and fresh lemon juice in equal proportions.

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.

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. Use a candy thermometer or conduct a cold water test to check if the fudge is done.

The Key lime has thinner rind and is smaller, seedier, more acidic and more aromatic than the Persian lime (Citrus × latifolia). It is valued for its characteristic flavor. The name comes from its association with the Florida Keys, where it is best known as the flavoring ingredient in Key lime pie.

Sweet limes differ from Persian limes and key limes, which are the sour varieties sold in grocery stores. All three fall under the genus Citrus but are separate species. And, given their basic differences, sweet and yellow sweet limes are easy to distinguish from these sour, green limes.

The most pivotal part of the pie is the filling. The “sweet spot” between the tart key lime, and the creamy condensed milk is crucial for the pie's quality. Here at Teak we understand that balancing these two ingredients is an art and take this concoction seriously. Our guests love our Killer Key Lime Pie.

Once the sugar has dissolved and the mixture has come to a boil, do not stir it. If you do, the sugar can crystallize, giving your fudge a gritty texture.

How to rescue fudge that won't set? ›

OPTION 3) Sieve together some powdered sugar and cocoa powder, and gradually work this into your unset fudge until it reaches the consistency of dough, then roll out and cut into squares, or shape into balls and then roll in powdered sugar (roll the balls in icing sugar, not yourself).

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.

Key limes are much smaller and rounder than regular limes. The average key lime weighs about 3/4 ounce, and it takes 18-20 key limes to yield a cup of juice. In contrast, a medium Persian lime weighs about 3 ounces, and it takes 5-6 regular limes to yield a cup of juice.

Nothing will bring forward the bright, citrusy, natural flavors and acidity like fresh squeezed limes. However, bottled lime juice is certainly a convenient option. If you decide to go this route, make sure to choose a high-quality brand that is 100% lime juice with no added sweeteners or flavors.

In terms of taste, key limes have a higher acidity, making them a little more tart than what we consider "regular limes." This makes them ideal for pairing with sweeter ingredients, hence the ever-popular Key lime pie.

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.

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.

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!

Homemade Fudge Doesn't Always Set

If your fudge doesn't firm up after a few hours, you either have too high an amount of liquid to sugar, or your mixture hasn't reached the soft-ball stage. Using a candy thermometer can help home cooks avoid this problem.
