All melons are made with varying consistencies of water. What we mean is that some melons are more watery than others. And watery melons may make ice cream that is more icy than creamy. While this recipe may work fine with cantaloupes, it may not work well with watermelons. Honestly, we haven't tried it with watermelons, so we really can't say. If you do try this recipe with any other type of melon, be sure to leave a comment down below. We, as well as other readers, would love to know how it went!
