Drink without a name

I invented a new drink today, and the result was good enough that I thought I’d share the recipe:

For six drinks 4 dl coconut milk 1 lime (juice and zest) 3 tbsp sugar 6 dl grapefruit soda ice

  1. Pour the coconut milk into a small bowl. Add lime zest, lime juice, and sugar. (I used brown sugar, but I doubt it matters much.)
  2. Stir vigorously.
  3. Split the mix between six glasses.
  4. Add the ice.
  5. Add the grapefruit soda.

I haven’t tried it, but I guess light rum or vodka might be the sort of thing you could add to this drink if you wanted an alcoholic variant.

Since this drink only has like three ingredients, I figure there’s virtually no chance I’m the first to invent it. If anyone knows one or more names for it, I’d be interested to hear it.
