Recipe Note
If you can't find kiwi and lime juice, use pineapple juice instead. You can also substitute lemon sorbet or lime sherbet with apple sorbet.
The punch has a nice green color on its own, but if you want a brighter green, add a few drops of green food coloring. Use gel food coloring because it is more intense and requires less in the drink.
Do not store the Polyjuice Potion for too long. Since it only takes a few minutes to put together, we recommend making it right before serving. Depending on how many people will consume the drink, you can double or even triple the ingredients.
