It is advisable to break a long term fast, 20 days would be long term, with a citrus fruit, tamoto juice or Watermelon juice. Although your traditional recipe sounds very enticing, I suggest to stay away from grains, oils and spices for if not 1.5 X number of fasting days, at least 1 X . So 20 days of fast would mean staying on raw organic foods, just the way we would find in nature not altered.
