I read something many weeks ago about personalising passion fruits with your kids initials. It explained that if you etched their initial into the soft green fruit on the vine it would scar and grow with the fruit until it matured.
I decided to try out an "S" "R" and "G" Finally the fruits are big and turned dusky purple. Tonight I cut open Sian's one and added it to a fruit salad she was having for tea. I 'm sure it tasted better for being personalised!
