You now have a bowl full of neatly sliced melon, ready for fruit salad, smoothies, or just plain old eating. I like to squeeze a bit of lime juice ...
Step 6: Slice!
I usually prefer to slice the melon against the rind in my hand, as shown below, then dump the entire batch into the bowl at once. Though sometimes I'll go ahead and ditch the rind, and slice against my thumb as shown in the final image below. Test, and see which method you prefer.
Yes, of course you can use a cutting board; but this method is much faster, and easier once you're used to it.
