With cantaloupes, the challenge is the ability to select one that is ready to eat. Good-quality cantaloupes will have large webbing or netting on the skin, will have yellow/orange coloring and be slightly soft on the stem end (firm elsewhere). The scar at the stem end should be a smooth with a well-rounded cavity. You can usually hear the seeds rattle inside a juicy melon when shaken. Avoid product with a rough stem end with portions of the stem remaining - this means the melon was harvested too early. Product with green coloring, soft or sunken spots or dark and dirty spots that look moldy are all signs of poor quality.
