We got some ruby red grapefruit for Christmas. I thought I would share how my grandmother taught me to cut them so they could be eaten easily. This grandmother lived in Florida for a good part of her life, quite close to orange groves. She served either orange or grapefruit halves for breakfast each morning.
After cutting it in half, start by removing any seeds. Then cut around the center circle of the grapefruit.
Next, cut between the grapefruit and the pith/peel.
Finally, slice between each section.
Even my little ones had no trouble getting the fruit out to enjoy after cutting it this way.
