I think may of us have been there with zucchini. Knowing they can grow fast, we routinely check on their growth, to pick at an ideal size.
But sometimes, Zucchini plants can get dense, and one can miss one. When I finally found this monster in August, it was over 60 cm (24 in) long and weighed in at 5.4 kg (12 lbs).
Yes, we ate it. But it was used mostly in soups and veggie patties, and tasted fine there.
