In the quest to keep caramel apples fresh for as long as possible, Joe Sofia from Cargill Cocoa & Chocolate investigates the effectiveness of a popular preservation method: the lemon juice trick. This method, which suggests dipping the wooden sticks in lemon juice before use, is believed to extend the shelf life of these sweet treats. But does it really work?

The shelf life of a caramel apple is typically only one to two weeks. The primary issue arises at the point where the stick is inserted into the apple. Over time, this area turns brown and becomes unappetizing due to enzymatic browning—a biochemical reaction triggered when apple flesh is exposed to oxygen. This phenomenon is what often limits the apple's appeal and shelf life.

Variables Affecting the Rate of Browning:

Temperature: Temperature plays a significant role; refrigerating caramel apples can slow down this process.

Apple variety: the variety of apple used can affect how quickly it browns, as different types have varying compositions

Without the stick, the shelf life of caramel apples could be considerably longer, since the caramel, nuts, and chocolate used in their preparation generally have a much longer shelf life.

Does the lemon juice trick really work?

The lemon juice trick involves soaking the wooden sticks in lemon juice before inserting them into the apples. It has been suggested that this trick helps to preserve the apples by reducing browning at the stick insertion point. However, Joe Sofia's testing did not reveal a significant difference between apples with lemon-soaked sticks and those with unsoaked sticks. After a week, both types of sticks—whether soaked in lemon juice or not—showed similar browning around the insertion point.

Given the limited impact of the lemon juice trick, another approach to extending the shelf life of caramel apples is to forgo the stick altogether. By using large dipping forks, beaker tongs, or scissor-style tongs to dip the apples in caramel, candy makers can avoid the browning issue associated with the stick. While this method may slow down the dipping process, it might be a worthwhile trade-off for those focused on maximizing freshness. For customer convenience, sticks could still be provided separately for those who prefer them.

In conclusion, while the lemon juice trick does not significantly extend the shelf life of caramel apples, exploring alternative methods like going stickless could offer a practical solution for preserving these delightful treats.

Consumers generally fall into two flavor camps: one that loves classic, comforting tastes and another that seeks out new, adventurous experiences. These preferences aren't fixed; people often switch between the two based on their mood or circumstances.

Experimental: Caramel with a Twist

Consumers love trying new flavor combinations, and adding a twist to classic caramel can make it more exciting and appealing. These twists can make familiar flavors feel fresh and interesting, encouraging people to explore new options they might otherwise overlook.

Twists and pairings

Caramel works well with a variety of inclusions to create multi-sensory experience. Healthier add-ins like seeds, nuts, and dried fruits are particularly popular. You can also experiment with more adventurous pairings, such as cocktail-inspired flavors, rosemary and sea salt, or cocoa nibs, to elevate your caramel creations and give them a premium perception. Caramel also has incredible potential to satisfy various eating occasions and consumer needs. For example, caramel and caramel products are the perfect solution for the rising trend of on-the-go consumer snacking.

In the spirit of exploring new and creative twists on caramel, we’re sharing 3 variations of caramel flavors to try this fall.

Old Fashioned Cocktail Caramels

If a caramel walked into a bar—a swanky, retro bar—it might walk out tasting like Shotwell Candy Co.’s “Old Fashioned” Cocktail Caramels. Described as “buttery soft caramel, infused with aromatic bitters, barrel-aged bourbon, and orange extract.”

Salted Rosemary Caramel Sauce

For herbaceous twist on your class caramel recipe, add a hint of fresh rosemary. This recipe for salted rosemary caramel sauce calls for boiled apple cider to add a more refined flavor and also recommends straining the caramel to remove any remaining pieces of rosemary.

Sweet tip: Speaking of caramel sauce, if you have a great caramel recipe and aren’t currently making caramel sauce, this could be a natural variation which would give your customers another way to enjoy your caramel.

Dark Chocolate Cocoa Nib Caramels

Especially if you already have chocolate caramels in your wheelhouse, adding cocoa nibs is sure to elevate your recipe with welcome texture and crunch elements. Check out this recipe from Love & Olive Oil.

Adding a twist to your caramel creations can elevate them from ordinary to interesting and even trendy, especially for younger consumers.
