Absolutely. My grandmother used to put them in the freezer for a few before cooking them as they seldom got a frost down in S Central FL. You know that area east of Bradenton.... Hope to see you in the AM. I'm sore around the biopsy site now. Feel like I'm running a low grade fever but not getting Ma up to take my temp.Do the collards taste better after they have been frosted on? Gnight Larry
