This juice requires the use of a juice machine such as the Champion, the Juice Man, Olympic, or the like. The sorrel adds a nice lemony tartness to the drink that helps the celery balance the sweetness of the carrots. For the apple, use no other than the Granny Smith, its sour flavor is an essential ingredient to this juice. ********************************************************************* Clean the carrots and remove any green parts. Wash the celery but do not remove the leaves. Cut the granny smith apple into 1/8th segments and remove the bitter seed pod. Rinse the sorrel leaves. Run everything through the juicer starting with the carrots. After one or two carrots have been run through the machine put the celery and sorrel through and then alternate carrots and apples until they are gone. Strain the juice through a couple layers of cheesecloth or a fine strainer to remove the pulp that makes it through the juicer screen if desired (this will produce a clear juice devoid of the grittyness, that some people do like).
