In a pan take a tsp of oil . Crackle jeera . Add onion ,ginger and chilli . Saute for 2-3 mins .
Add carrot to it . Add some salt and saute for 1-2 mins . Switch off .
Add grated / mashed sweet potatoes .
Add all the spice powders ie salt , chilli powder , chaat masala , Aamchoor powder , garam maslala and coriander leaves .
Mix everything well . Taste test and add if anything required . Divide the dough to small / medium equal size balls . Shape them depending on your choice . You can do round flat disc /oval / heart shape / use any cookie cutter to give special shape .
In a small bowl , mix maida or corn flour with 2 to 3 tbsp of water such that no lumps are formed . The batter should not be thick . In another plate spread breadcrumbs. Dip cutlet in cornflour mix to coat all sides and then coat it with bread crumbs well, Repeat same for rest of the cutlets . Keep cutlets covered in refrigerator for 30 mins / more to firm them . You can finish cutlet preparation till here and refrigerate and fry fresh when you are about to serve .
The coated cutlets can be deep fried / shallow fried on tawa .
Serve sweet potato Cutlets hot with ketchup / green chutney .
Take care that sweet potatoes while boiling don't absorb excess water . If they do ,after cooking place the sweet potatoes on tissue paper so that excess water goes .
Addition of spices , herbs , veggies is all your choice. You can go crazy with the filling and do plus or minus from the above mentioned list. If you want you can do plain sweet potato filling too .
The final dough should not be watery type . else it will be oo soft and drink oil . In that case you can add some bread or cornfllour to absorb excess moisture .
You can either deep fry them or shallow fry them on tawa. Both taste equally good.But if you are doing in large quantity , better to deep fry as it gets over equally .
