Leave it to Alton Brown to come up with the best hacks for everything in the kitchen, including how to juice a watermelon. Alton's two secret tools — a biscuit cutter and an immersion blender — are key in the process of extracting all the juice in a matter of seconds. After all, Alton despises unitaskers, so it's no surprise that he found a brilliant way to repurpose two common tools you have lying around in the kitchen. Alton shared a one-minute video that illustrates the easy method.
First, tilt the watermelon on its side and use a three-inch biscuit cutter to create a uniform hole in the bottom of the fruit. Use a knife to trace the hole and fully penetrate the skin to remove the cut-out section. Then, put the immersion blender straight into the opening you've created and blend the contents of the watermelon inside. From there, you can pour the juice into cup or pitcher, and you can put it through a sieve to remove any pulp and seeds. Or, as someone mentioned in the comments, "Just add vodka and a straw" (touché). Watch Alton's full video to visualize the process for yourself, and prepare to try this at home the next time you're ready to crack into your fresh watermelon.
