Happy Memorial Day! I meant to post this much earlier in the day... but life kinda happened. Hopefully you will be able to use this as the summer grows on us.
Step 1: Cut both ends of the watermelon off and stand the watermelon up on end as shown here. Using the seeds as a visual guide, cut vertically down the watermelon wherever there is a seed cluster. You will do this about eight times all around the watermelon.
Step 2: After slicing vertically down the watermelon, wiggle a piece out. It should break off easily where the seeds surround the heart of the watermelon (as seen in this picture). The first piece will be the hardest to get off.
Step 3: Use a spoon to scrape the seeds off of the watermelon into your sink or garbage can.
This is what it will look like after the seeds are scraped off. Sometimes the ridges are along the sides instead of on the top as seen here. Just follow the line of seeds with your spoon as you see it patterned on the melon.
Step 4: After each side piece has had the seeds scraped off of it, slice it into pieces for your bowl. Repeat steps 2 through 4 for each of the side pieces of the watermelon.
Step 5: After you have removed and scraped the seeds off of the side pieces, all you will have left is the heart of the watermelon--looking something like this.
Use the spoon to scrape off the seeds, just like you did with the side pieces. (Sorry about the glare on this picture.)
This is what the heart will look like after the seeds have been scraped off of it.
Step 6: Finally, chop up the heart and add to your bowl of watermelon. (Or save it for a treat for yourself later!)
