Saving tomato seeds is easy. Here’s how to do it like a pro, on your kitchen counter.
This method of tomato seed saving is called the “fermentation” method. All you need to do is let the seeds sit and stew for a few days, which will rot off the jelly on their seed coats. Then you can rinse away the gunk and get lovely seeds that will germinate better than they would if you dried them right from the fruit.
