Melon Readiness
One important thing I learned on the farm is how to identify which melons are ripe. While the color is usually a good indicator, the best way to figure out if the fruit is ready to go is to actually smell it - if it has that sweet melon aroma, it's good to go.
Melon Options
You can buy melon juice from your farmers market or juice your own cantaloupe right before you make the cocktail. I obviously recommend the ladder, as it will be much fresher. And if you don't have a juicer, you can slice melon into 1-inch cubes and muddle it before adding the rest of the ingredients in the shaker. About 4-5 cubes should be enough for one cocktail.
