No have never eaten a cattails, they do grow around here, I believe I knew they were edible but have never tried them. Have to look in my book and see what it says about them.Those Morels made me hungry. Just had shiitake, mitake and Shimegi mushrooms cooked with garlic and butter on toast.
@oldmaninbc have you ever tried cats tails?
They’re a traditional Māori food source in NZ, I believe they are in Canada too(I saw them on a trailer park boys episode)
I have to go my Mrs is giving me the look, where is my supper.
Will answer your other question tomorrow.
