I froze a big chunk of fresh ginger almost a year ago, wacked off a hunk, thawed it out, minced it and it was just the same as fresh. It hardly lasts 2 weeks in the fridge. Nothing like fresh ginger in stir fry (in the cast iron skillet )
I thought when I read your Subject line that you were going to divulge a secret that only "Fred Astaire" knew about. He always just washed her with that nice smelling soap and then sprinkled her in all the right places with a special powder. And man, was she "fresh".
Sorry, I couldn't resist that one. Did you package it a special way when you originally froze it. I am surprised that you didn't loose the real flavor during the year long period.
I just had it doubled wraped in a plastic bag. I'm surprised,too. I thought it would be all mushy after it thawed. Probably not quite as crisp as fresh, but almost. I was thinking that I could just use a grater on the frozen piece and not even worry about thawing and mincing.
