Another great recipe. I love beet pickles but I'm always cooking the beets. It takes a couple of hours though. Need to try this as well. How tough is the beet after three days? I like them tender but then again, having them raw is a huge advantage as you can preserve all the vitamins. Again, I'd suggest horseradish in this as well. it gives a good flavor.
The beets are a little crunchy. Even after 2 weeks they are crunchy. If I were you I would stick to cooking them if you are making a specialty dish, but if you are eating them on your own, raw is a nice taste. If you shred them in the food processor or with a grater, they will be much softer, or if you slice them thinly.
