Honeydew melons are a variety of Muskmelon and are considered the sweetest of all melons. Good-quality Honeydew melons will turn a creamy yellow color and the skin will have a slightly waxy feel when ripe. They will be firm with a small amount of softness at the stem and will be fairly large - those weighing about 5 pounds have the best flavor. Sometimes, the seeds of an especially juicy melon will rattle if the melon is shaken.
