How to Make Russian Sorrel Borscht Without Beets

In a large saucepan or Dutch oven, melt 2 tablespoons butter or margarine or heat the oil. Sauté 1 pound young washed and stemmed sorrel leaves and 1 large minced onion for about 10 minutes or until sorrel is wilted and onions are translucent. Add 6 cups water or chicken stock and 1 teaspoon kosher salt or to taste. Bring to a boil. Reduce heat and simmer 30 minutes. Remove from heat and stir in 2 tablespoons sugar and juice of 1 lemon a little at a time, tasting after each addition of lemon juice, until your desired tartness is achieved.
