How to Make It
In a small saucepan, combine the cranberries, granulated sugar and water and simmer, crushing the berries, until jammy, 8 minutes. Let cool slightly. Transfer to a bowl and add the confectioners' sugar, corn syrup, vanilla and salt. Using a handheld electric mixer, beat at medium speed until smooth. Use the glaze right away, or cover with plastic wrap and refrigerate for up to 1 week.
