First, choose a firm, fairly hard melon that looks and smells fresh. Avoid melons that contain bruises and/or moldy patches.
How to tell if a Cantaloupe is Ripe:
It if still has a partial stem attached, chances are the melon has not ripened properly. Smell the end (near the stem), if it has little or no smell avoid that fruit and simply pick out a better one.
How to tell if a Honeydew Melon is Ripe: at the "stem" end or Blossom end of the melon, gently press your thump into the slight indentation. You want a melon that has a gently give, but not one where your thumb goes through (overripe/rotten!) or where the fruit offers no give at all, as this means the fruit is not ripe.
Once the rind has been removed, dice the fruit, toss it into a bowl, cover it and place it in the fridge. As you can see from the smaller container pictured above, we've found over the years that these 1 cup ziploc containers create perfect 100 calorie snack packs or 100 calorie portion control meals.
