I can never tell how to pick a good watermelon. My go to method as of now is to look at the color and pick one that is a healthy dark green all around. Then I use my knuckles and knock on the melon while holding it and listen for a certain hollow sound. I'm sure that people at the grocery store must think I'm insane as I assess my melons. I mean a cantaloupe you can just pick up and smell if it's ripe, but a watermelon.. Who the hell knows ?
Anyways this time I got lucky.
Combined puréed watermelon with the juice of two limes, and some simple syrup.
Into the bottom of the Popsicle molds I poured some Tajin. I was hoping that it would stay at the bottom of the molds, but when I poured in the watermelon purée it seemed to mix throughout, also the more foamy watermelon juice stayed on the top. Will have to taste test tomorrow and see how these came out!
