I agree with the earthy taste but is not a dirt flavor. I think they take on a taste of what they are grown in. Hadn't had beet in a long time so I grew them one year. Cooked a bunch for dinner one night and got the scare of my life the next morning as the bowl had a red tinge to it. Thought I had ruptured an intestine. Took a minute to remember the beets.
My grandmother and mom would on occasion make borscht. Borscht is a traditional soup hailing from Russia and Eastern Europe. It wouldn’t be borscht without beets. I loved it!
To me, they don't taste like dirt or sweet. Beets taste like beets. Good and healthy. I buy sometimes for me, Mrs Bearfoot does not care for beets.
