There's actually a slightly stronger recipe as well (when used, the report comment will be "Everyone loved your luxury juice recipe! But can you afford the costs?"), but it's very costly to use. You'll usually want to start with a cheap recipe at the start of the game (see tips). Firebolt's recipe is likely the best balance between price and taste.
I've had a lot of success with 3 pineapples and 2 mangos (weak recipe). Then, when I upgrade to "Fancy Cups," I'll use my luxury recipe: 5 pineapples and 3 mangoes.
