I've always blamed it on improper pollination. It happens to a couple now and then. Nothing to worry about. It's not happening to bunches, is it?

I'd say Siamese twins where one twin is a zombie. There's a term for it, at least among zombies.

Kevin, I think these two were the only ones out of ~20 pods I picked that day. The strange thing is that as far as I can tell, the growths showed up after the pods ripened.

hmmm.

I always figured it as a mutation of some sort. Maybe it shows up LATER in pod development. Never bothered me... i still eat 'em. :)

Kevin, I'll eat 'em, don' t you worry :-)
