This is now my go-to homemade cherry limeade recipe:
1 - 2 liter of Sierra Mist
1 can of limeade concentrate - thawed
1 cup maraschino syrup
8 maraschino cherries (optional)
Add first 3 ingredients to a large pitcher. Cut both limes into quarters, squeeze a little juice out of each of them into the pitcher before dropping into pitcher. Add maraschino cherries to the pitcher, stir and enjoy over ice.
