I love Good Grips products. The vegetable peeler, the 4-quart mixing bowl, the silicone spatula and the whisk all get a big thumbs up in my kitchen. And the salad spinner? I want to marry it. (Except I'm already planning to marry this soup.)
So OXO's decision to make and market this particular gadget baffles me. Maybe I just don't buy mangoes enough to appreciate its existence, but I can't see how this wouldn't create more of a mess than the one you were trying to avoid.
When's the last time you sliced open a mango with a knife? Could you tell which way the seed was oriented? Did the flesh cut away neatly from the seed with no mess? Did you worry the half-cut slippery fruit was going to shoot out from under your knife and land in the dog's water dish?
If the answer is yes, maybe you think this slicer would help. Me, I can't picture using it without creating a sticky, pulpy mess, first trying to orient it to the seed, and then probably getting it stuck halfway down because the seed ends up being bigger than the slicer allows.
That's the way it seems to me. But maybe I'm wrong. If you love your mango splitter the way I love my salad spinner, let me know!
