Nigella, Aniseed, Star Anise and others. Have previously tried making jam which I enjoyed yet the ghee may have contributed to my weight. Could you please give clear instructions which I can make to combinations? Would Basti Enema be useful? Willing to fast at home but dont know how. It is summer in UK.
