While making kachori's you can prick the dough with fork before dropping it into the oil so that it does not puff up.
I have not pricked as I liked it to be puffed.
while making the stuffing you can add sugar to it will be a great combination of mixed flavours.
You can rest the dough even for 30 minutes.
Always cook in medium flame not high.
After closing the kachori's with stuffing you can either roll with a rolling pin or press simply with hands to make it flat.
When adding ghee to make dough it can be little warm.
For seasoning also you can very well use ghee instead of oil.
Adding besan is optional its only for binding purpose.
Adding black cumin is also optional.
