I cut a tumbo open length-wise to discover a very pretty orange, passionfruit-like cluster of seeds and pulp. (Turns out another name for tumbo is banana passionfruit - how appropriate!) I tasted the fruit as I would passionfruit: by eating the pulp around the seeds. At first I wasn't a fan. The taste is mild but a bit chalky, and certainly not as juicy as I'd expected. A few more seeds in, though, and the tumbo was starting to win me over. I've since seen tumbos stacked up at juice stands and I'm curious to try them blended and strained and maybe mixed with a little sugar (or pineapple juice).
