Step 5: Remove rind
Just hold the melon wedge in your hand, and slide the paring knife between the rind and melon flesh along the line where the color changes.
Advanced technique: I often leave the last little bit of melon attached to the rind. This keep the melon wedge from slipping off its rind as I slice it, which is super-handy. Check out the video in the intro step if you're not sure what I mean.
