I have been using this recipe for about 25 years now when our beets come off. We love them. I got the recipe from a CANNING, PRESERVING,& FREEZING COOKBOOK (Favorite Recipes Of Home Economics Teachers) that I sold to my Mom when I was in Home Economics In 1974. She used this book & now it's mine. One of my favorites.
I swear by this canned beetroot recipe. I've made this so many times and alter the liquid to my taste. Much healthier and better than any store bought pre-made beets, so much so that I do not even buy pre-made beetroot anymore!
