Gillyweed doesn't exist outside of Harry Potter's magical world, but this concotion gives you the illusion of "slimy, grey-green rat tails" and tastes a whole lot fresher too! Who wants rat tails anyway?

This recipe is inspired by Harry Potter and the Goblet of Fire.

If given a potion that would give you gills and webbed toes and allow you to breathe underwater, would you drink it?


Level: Easy

Total: 30 min (if using cooling time)

Active: 15 min

Yield: 8 cups


1 English cucumber

1/2 cup mint sprigs

2 limes

1/2 gallon (8 cups or almost 2 litres) flat or sparkling water


  1. Using a vegetable peeler, peel the cucumber lengthwise, reserving both peel and the flesh until you reach the seedy middle, then stop.

  2. Peel the zest from the limes into curls or strips.

  3. Juice the limes and reserve.

  4. Add cucumber peel, springs of mint, and lime juice and zest to a large pitcher, then add cold water to top.

  5. The longer the fruit steeps in the water, the more flavor is infused.

  6. If using flat water you can allow the ingredients to mingle in the fridge for 30 minutes. If using sparkling water, serve immediately to retain the carbonation.
