Candied fruit is fresh fruit that has been preserved by slowly replacing its natural water content with sugar. The process, called osmotic dehydration, produces fruit that is intensely sweet, chewy, and shelf-stable for up to a year. You’ve likely encountered it in holiday fruitcakes, panettone, or as jewel-toned toppings on pastries, even if you didn’t know exactly how it was made.
How the Candying Process Works
At its core, candying relies on a simple principle: water moves from areas of low sugar concentration to areas of high sugar concentration when separated by a membrane. Fruit cells act as that membrane. When you submerge fruit pieces in a thick sugar syrup, water flows out of the fruit cells while sugar migrates in. Along with the water, small amounts of the fruit’s natural acids, minerals, and vitamins also leach into the syrup, which is why candied fruit tastes sweeter and less tart than the original.
The traditional method takes between 10 and 14 days. The fruit is soaked in progressively stronger sugar syrups, with the concentration increased a little each day. Rushing this step degrades the fruit’s texture and appearance. Only the final drying phase can be slightly accelerated without sacrificing quality. After the soaking is complete, the fruit is drained for about 30 minutes, washed or wiped to remove sticky residue, then dried for 8 to 12 hours at a gentle heat or in the shade. The result is a piece of fruit where sugar has essentially replaced the water inside each cell, creating a dense, translucent, preserved product.
Candied, Glacé, and Crystallized: What’s Different
These three terms get used interchangeably, but they describe distinct finishing steps applied to the same base product.
- Candied fruit is the base version: fruit soaked in sugar syrup, drained, and dried until it’s no longer sticky. The surface is smooth and slightly matte.
- Glacé fruit is candied fruit dipped in a hot sugar glaze (a 2:1 sugar-to-water syrup boiled to about 113°C), then dried again. This gives it a shiny, translucent coating and a slightly crisp exterior. Glacé cherries are the most common example.
- Crystallized fruit is candied fruit coated in visible sugar crystals. The fruit sits in a concentrated syrup for 12 to 18 hours while crystals form on its surface, then it’s dried at room temperature. The sparkling, granular texture makes crystallized ginger and citrus peel popular as standalone confections.
A Preservation Technique With Ancient Roots
People have been preserving fruit in sugar for thousands of years. The technique traces back to Chinese and Mesopotamian cultures, where the primary goal was simply preventing food from spoiling. Romans preserved fish in honey using a similar principle, but the direct ancestors of modern candied fruit are attributed to Arab culture. Royal Arab banquets featured candied citrus fruits and roses, and as Arab influence spread westward through trade and conquest, the technique traveled with it into European kitchens.
By the Middle Ages, candied fruit had become a luxury across Europe, particularly in France and Italy, where the tradition remains deeply rooted today. The city of Apt in Provence still calls itself the world capital of candied fruit.
Where You’ll Find Candied Fruit
Candied fruit plays a central role in holiday baking traditions around the world. Italian panettone, the tall, dome-shaped Christmas bread from Milan, is filled with candied lemon peel, orange peel, and glacé cherries. British and American fruitcakes rely heavily on a mix of candied citrus, pineapple, and cherries. German stollen, a dense Christmas bread dusted in powdered sugar, uses candied orange and lemon peel alongside dried fruits and marzipan.
Beyond holiday breads, candied fruit shows up in Sicilian cassata cake, French calissons (almond-shaped confections from Aix-en-Provence), and across Latin American and Middle Eastern pastry traditions. Candied ginger is widely used in Asian cuisines both as a snack and a cooking ingredient. Candied citrus peel, dipped halfway in dark chocolate, is a classic confection on its own.
Nutritional Profile
Candied fruit is calorie-dense, as you’d expect from something saturated with sugar. A 28-gram serving (about one ounce) contains roughly 90 calories and 23 grams of carbohydrates, nearly all from sugar. That means sugar makes up over 80% of the weight. The original fruit’s fiber largely survives the process, but most of its water-soluble vitamins and minerals are lost during the repeated soaking, leaching into the discarded syrup.
In baking, candied fruit is typically used in small quantities, so the per-serving impact in a slice of panettone or fruitcake is modest. Eating it by the handful, though, adds up quickly.
Storage and Shelf Life
Properly made candied fruit stores well because its high sugar content creates an environment hostile to bacteria and mold. Kept in an airtight container at cool room temperature (roughly 4 to 20°C) with moderate humidity around 65%, it lasts about a year. Glacé fruit in particular should stay sealed to retain its crisp coating.
Very cold storage can actually cause problems. If temperatures drop too low, the glucose in the fruit can crystallize on the surface, creating a grainy, unpleasant texture. A cool pantry or cupboard works better than a refrigerator for long-term storage. If the fruit becomes sticky or develops off smells, it has absorbed too much moisture and should be discarded.
