Among the most beloved holiday treats, fudge holds pride of place in gifted Christmas tins and on holiday party dessert tables. Make no mistake, the diversity of fudge flavors is endless, but when it comes to Christmas Fudge, we have the firm belief that simple and classic chocolate fudge is almost always a better choice than anything elaborate and novel. Our recipe makes the most of bittersweet and unsweetened baking chocolate by letting their flavor stand on their own while including a few other ingredients to enhance the richness and the silkiness of the fudge itself. Sweetened condensed milk and butter are used to transform the melted chocolate into a sweetened and milky ganache, while the salt, espresso powder, and vanilla compliment the flavor of the chocolate and make the depths of that flavor more pronounced. The secret ingredient in this recipe is the corn syrup which prevents any crystal formation in the fudge and allows the finished product to be perfectly smooth with a slight chew rather than a crumbly, powdery, and altogether disappointing piece of crystalized fudge. To keep with the theme of simplicity, the decoration for this fudge is a mix of red, green, and white sprinkles that lend a delightful crunchy contrast to the velvety texture of the fudge. Finally, the flake salt called for in the recipe is optional, but when used, it enhances the fudge squares with a subtle saltiness while also adding the visual appeal of flaky crystals—taking something that looks almost like a kid’s treat at Christmas and elevating it to something fun and sophisticated.
