Soak the raw cashewnuts in warm water fro 8 hours ,previous night soaking does this .Peel the skin ,divide them and put them in fresh water ,be careful as the stains make fingers black a lil bit of cocnut oil rubbed on ur fingers will help.put them in fresh water and clean twice.
If u get frozen raw peeled cashews then u can directly start to cook.
Heat oil for seasoning.Add mustard when it splutters add cumin seeds ,asafoetida.
Then add the chillis.saute.add potato,stir once then add capsicum.stir again.let it cook for a minute.then add the cashewnuts.close lid and cook till done.add salt and stironce again.do not overcook.when done u can add fresh grated coconut for garnishing.
It is served with rice and dal.The best it is with puris.Konkani style :-).
Using a small pressure cooker can make this dish more yummy.Just one whistle and the curry is done.
