Candied redirects here. For other meanings see the verb ‘to candy’. Candied fruit, also known as crystallized fruit or Glacé fruit, has been around since the 14th century. Whole fruit, smaller pieces of fruit, or pieces of peel, are placed in heated sugar syrup, which absorbs the moisture from within the fruit and eventually preserves it. Depending on size and type of fruit, this process of preservation can take from several days to several months.
