Use this raspberry simple syrup to make our valentine cake.
Prepare an ice water bath. In a small saucepan, combine the sugar and 1/2 cup water; bring to a boil over medium-high heat. Cook, stirring occasionally, until the sugar has completely dissolved, about 10 minutes. Stir in the framboise and set the pot over ice bath. Stir occasionally, until completely chilled. Can be stored refrigerated in an airtight container for up to 2 months.
