I posted last week about the mutant "peppermato" we found in our garden, but it turns out the joke is on me. My Polish brother-in-law gave us a tomato plant, which we planted near a red pepper plant.

It turns out we are not the harbingers of a mutant cross-breed, but the owners of a Polish heirloom tomato plant called an Opalka. The fruit is shaped like a banana pepper and has very few seeds, but makes great sauce, apparently. Ours haven't ripened beyond a reddish-orange, so we may never know.
