What a great gadget, if you're doing a lot of mangoes or even one or two. No more flying mangoes on the floor. William Sonoma sells it for $12 and it really works. You put the thing over the mango, so that the oval on the gadget is in line with the pit and just press down. Then you crosscut score the inside of the halves, not cutting into the skin. Then you turn the halves inside out and you are done! There is not a lot better than mangoes, blueberries and bryer's lactose free vanilla ice cream! I got their 14 x 16 pizza stone and the mango depitter fir $6.00 when I returned the Cooks Illustrarted book on BBQ that I got for Hannukah. Great book but very basic.
