1 tablespoon Cointreau or other orange liqueur like Grand Marnier or triple sec (optional)
1/4 cup water
Instructions
Place the raspberries, maple syrup, vanilla, Cointreau, and water in a saucepan. Heat over medium heat. When it starts to bubble rapidly, stir constantly for 1 to 2 minutes until thickened and the fruit breaks down.
Reduce the heat until raspberries bubble at a low simmer. Cook 10 to 12 minutes until thickened and the berries break down. For a smooth sauce, pass it through a fine mesh strainer using a spatula to strain out the seeds. Serve warm or refrigerate until serving (store refrigerated for up to 1 week).
