Once a cantaloupe is harvested off the vine, it will no longer sweeten. There are a few ways to ripen a whole cantaloupe if it was picked to soon, but not when it has been cut into. For melons already cut, you can try to get it to soften a bit by placing it in a container with a little lemon juice or orange juice. Place in the refrigerator until ready to serve (storing at room temperature can encourage bacteria). Use within a day or two.
