First off, if you're using a Kaloud Lotus you do not need foil, that should sit right on top of your bowl. This could be why your flavor is bad. Also, how many coals do you have in your lotus? Once your coals are hot enough to use you should put them in the lotus with the top closed on top of the bowl for about 10 minutes and then you should be good to go. After 10 min or so you can adjust the airflow on the top of the lotus to reduce some of the heat if needed. This should help you.
