Some people swear you must peel ginger with a spoon. They’ll tell you it’s the only way to avoid waste and keep the flavor pure. I say: if the skin is thin and young, leave it on.
Just give it a good scrub with a vegetable brush. The skin is perfectly edible, and honestly, who has time to fumble with a peeler over a lumpy root?
If the skin is thick and papery—like my grandpa’s hands in winter—then yes, peel it. A regular spoon’s edge works like magic to scrape it right off.
