My goto stuffing for puff or sandwich had mostly potatoes and then some vegetables + masala powders. And I would avoid cabbage(and it’s family). And because there was lot of potatoes, masalas would lose flavor by the end of the day.
This stuffing happened by chance. One time while making palya for puff, since I didn’t have enough potatoes, I added cabbage. This turned out exactly like Bangalore Iyengar bakery style puff. Cabbage not only complimented all masala powders very nicely but made it taste more like Indo Chinese. Super happy with this accidental discovery..
Do try!
