Very tasty. Shisha lemon is an authentic fresh lemon juice flavoring. Unlike Lemon Sicily, which is more like a lemon liqueur or dessert sauce. If you don't have INW Shisha lemon, use whatever lemon you think replicates true freshly squeezed lemon juice. Nothing else is changeable for this one. If you don't have Pink Panther, you could double up on the Shisha Raspberry, it won't be the same, but it'll still be a nice raspberry lemonade.
