Yes, and they aren't grown around here! Nary an acre that I know about.
My garden growing season would be coming to an end and - woosh - there were all the beans! Then, they were gone!
Blanching and freezing didn't even occur to me until after my 2011 harvest. I was curious where others were finding edamame. Duh, in the freezers at the stores! Oh yeah, they could be frozen and not just eaten fresh.
Well, I CAN make tofu but it isn't my favorite food in the world . . . On the other hand, edamame is really good! I get so used to eating fresh veggies by late in the season that the soybean harvest would just kind of slip right thru my fingers each year and I'd be left with more dry beans than I cared to have!
I hope frozen edamame is as good as straight-from-the-garden. Gotta try.
