I am wondering if you have tried Red Ursa kale? I grew some of that variety this past year and I really liked it a lot! I also grew the Scotch Blue Curly which I believe is what you have pictured. ?
Another benefit to cooking greens is it removes the Goitrogens (which block Iodine absorbtion) even though it does remove some of the nutriens as you have stated. :)
Thank you for sharing your recipe! I will have to try it out!
I haven't tried the Red Ursa Kale - the one I have came without name :)
hahaha - no secret - just lazy gardeners who do not label things like seeds :) Makes sense that Russian varieties would do well in a short growing season. Here, they might get too hot... :)
