To make the syrup, place all the ingredients in a small saucepan over medium heat. Bring to a boil and then simmer for about five minutes, until the liquid surrounding the fruit is a bright pinkish-red and the strawberries themselves are much less vibrant.
Let the syrup cool for five minutes, then pour through a fine-mesh strainer into a bowl or jar, using a spoon to push on the solids in the strainer to extract as much liquid as possible.
Allow the syrup to cool to room temperature before making drinks with it, or store covered in the refrigerator for up to a week.
To make each drink, put 2-3 tablespoons of syrup in the bottom of an 8- to 10-ounce glass. You can always start with two tablespoons and add more later if you'd like. Pour in sparkling water and/or champagne until the glass is almost full. Add two ice cubes. Garnish with a halved orange slice, half a strawberry, and a sprig of mint, and serve right away.
