Consumer tips
- 1
Always wash the outside of both melons before slicing to prevent dragging bacteria from the rind into the flesh.
- 2
A ripe Watermelon should feel heavy for its size and have a creamy yellow spot where it sat on the ground.
- 3
Honeydew is ripe when the rind feels slightly tacky or velvety, not perfectly smooth and slick.
- 4
Store cut melon in an airtight container in the fridge and consume within 3 to 4 days.
