Step 1

For the strawberry syrup: Heat the strawberries, sugar and 3/4 cup water in a medium saucepan until boiling. Reduce the heat to low and simmer until the mixture thickens and reduces, about 12 minutes. Remove from the heat, cover and let sit to infuse for 10 minutes. Mash the fruit to a pulp, then strain the syrup into an airtight container. Discard the solids. Refrigerate the syrup until ready to use and up to 1 week.

Step 2

For the strawberry punch: Combine the strawberry syrup, pineapple juice, orange juice, orange liqueur and rum in a pitcher. Stir until combined, then cover and refrigerate until chilled and ready to serve.

Step 3

When ready to use, stir, then divide between 6 glasses filled with ice. Top each beverage with 1/4 cup sparkling wine or sparkling water and garnish with a fresh strawberry.
