I've got to admit that this is the first time I've ever had passion fruit. I randomly came across it and thought: yep, today's the day I buy it! I didn't even know the outer shell was not edible, I was planning on using the seeds in the smoothie and just eating the rest. It's a good thing I googled it and found out before I had it! And just incase you haven't had it before either, it was harder cutting into the shell than I thought it would be, and it has a pretty strong smell and taste for such a small fruit!
Anyways, this smoothie reminds me of a hot summer day so all the more reason to have it! Who drinks for nutrients anyways? (definitely me from now on)
