Are they edible?

I know the usual passion fruit, as sold in greengrocers, is a sort of
wrinkled brown-skinned thing with yellowy "jelly" coating on the seeds so am
not sure whether I ought to be taking a chance with Mother's.

Chances are these are Caerulea fruits and as such they are edible but
don't taste very nice!

They won't harm you anyway!
