I can't speak for any method other than window sill ripening, but those come out tasting delicious. I almost always have to pick my slicers early, because the slugs will get to them as soon as they start to ripen up if I leave them too long. No loss of flavor quality, IMO.

Don't know if any of you appreciate southern food, but "fried green tomatoes" are a good use of green tomatoes. Tasty.
