This is a bit more expensive due to fresh fruit but doesn't require a freezer except for ice cubes. So could be possible for people with only a bar fridge. You can use what you have (you don't need dragonfruit) but watermelon is usually always an ingredient. Traditionally the liquid was a floral/berry tea but in modern day it's a mix of strawberry milk and Sprite.
