- 2/3 c. ginger simple syrup, plus more to taste
- 2/3 c. fresh lime juice (about 1 bag of limes), or more
- 18 oz. fresh raspberries
- 2 2L bottles of seltzer water, chilled
- raspberry ice cubes
- 2 more limes, sliced
Mix ginger simple syrup, lime juice, and raspberry puree in a container and refrigerate overnight for the flavors to blend.
Put raspberry mix in punch bowl. Carefully add a 2L bottle of seltzer water. (It will fizz violently.) Add seltzer water from second bottle to top off. Add more ginger simple syrup to taste. Add raspberry ice cubes and lime slices.
For raspberry ice cubes: Fill one ice cube tray with water and 1 fresh raspberry per cube. Freeze.
For ginger simple syrup: Put into a small saucepan 1 c. water, 1 c. sugar, and peeled, sliced ginger (at least half a cup, most of a Trader Joe's pkg). Bring to a simmer. Remove from heat and steep for a while. Strain out solids.
