Mango are delicious! Preparing Mangos is a pain in the ass though. It takes a bit of work to split a mango with out hitting the seed or having a lot of waste. Luckily OXO has released a gadget to solve this pressing problem. The OXO Mango Splitter works by passing an oval shaped knife through the mango and in the process, coring the pit. This is such a revolutionary kitchen gadget that NPR did a story on it: NPR Story

Testing
So far I have only used the splitter on two mangos and so far it has worked great. The only trouble I have had is with a mango that was really ripe. The splitter has a little trouble with the tough skin and soft flesh underneath.

There was also overly little waste around the pit. I could probably do better with a knife… but not much. With a knife you take a flat cross section, which leaves a lot of waste around the top and sides of the pit. With the splitter you take an oval shaped core out and you have less waste on the sides. Either way the Mango Splitter makes it much quicker, easier and more enjoyable to eat Mangos! If you are a mango fan, pick one up!
