Using this method, the flesh of the melon never touches the cutting board so flavor from previously cut vegetables (like onions) won't transfer to the watermelon. No more mess and easy to clean up!
Lay your watermelon on a flat surface suitable for cutting.
Slice the watermelon down the middle from top to bottom long ways.
Here are the two halves...
Now slice the watermelon half lengthwise from end to end.
Another angle for you.
Once you've completed this step your have two quarters sliced from and to end.
Now take your smaller knife and follow the rind through the curve of the watermelon.
Spin the watermelon around and repeat this step on the other side.
Be sure your slice separates the watermelon flesh from the rind.
Slice downward in uniform slices from end to end be sure your slices reach all the way down to the bottom of the rind.
Using your fingers press the alternating slices in different directions to make easier serving access.
It should look like this when you're finished.
Won't last long!
