Notes
Use exact given qunatities of oil for the best results as if you exceed oil quantity it becomes difficult to grind the spices.
Also Fry the spices in same order for the best results as this is the oder that maximises the aroma and will retain it in the masala.
You can use the Not sieved through contents in the non veg gravies or when you would be grinding masala with wet contents.
The above ingredients make around 3/4Kg of masala
