Earl,
I will be very impressed if you get those pickled pepper seeds to germinate. I'm thinking of how vinegar "cooks" fish when they are pickled, the flesh actually changes to a white color from the translucent state. Don't you think that the seed coat will eventually be softened and penetrated by the vinegar if the seeds sit there long enough? Or is the percentage of vinegar to water in the brine too low to kill the viability in your opinion? Great idea if it works! Please keep us informed of your progress, ok?
