To cut a mango, use a sharp knife to make a cut through one side of mango, sliding knife next to seed. Repeat on other side of seed, making 2 large pieces. Make cuts in crosshatch fashion through flesh just to peel; bend peel back and carefully slide knife between peel and flesh to separate. Discard peel; chop flesh.
