2 bananas, peeled and cut into 1/2-in.-thick slices (about 1 1/2 cups slices)
1 cup granulated sugar
1 cup water
3/4 cup (6 oz.) light rum
6 tablespoons fresh orange juice (from 1 or 2 oranges)
6 tablespoons Banana Simple Syrup
1/4 cup fresh lime juice (from 2 limes)
2 ripe bananas
2 tablespoons (1 oz.) Cointreau or other orange-flavored liqueur
2 cups ice
How to Make It
Prepare the Banana Simple Syrup: Combine banana slices, granulated sugar, and water in a small saucepan over medium-high. Bring to a simmer, stirring often and gently mashing banana pieces slightly, until sugar dissolves, about 5 minutes. Remove from heat, and let cool to room temperature, about 30 minutes. Pour mixture through a wire-mesh strainer, stirring to remove as much syrup from solids as possible without pressing on solids. Discard solids. Refrigerate syrup in an airtight container up to 1 week.
Prepare the Daiquiri: Process rum, orange juice, Banana Simple Syrup, lime juice, bananas, Cointreau, and ice in a blender on high until mixture is smooth and icy, about 30 seconds. Pour into 2 frozen 16-ounce glasses, and serve immediately.
