Masala Dosa — Potato Filling and Assembly (मसाला डोसा)

Karnataka and Tamil Nadu; the masala dosa's origin is contested — both Mysore and Udupi claim the invention; the MTR (Mavalli Tiffin Rooms) restaurant in Bangalore is associated with the standardisation of the form

Masala dosa (मसाला डोसा) is the filling-enhanced version of plain dosa: a lightly spiced potato filling (batata masala, from potatoes cooked with mustard seeds, urad dal, curry leaf, turmeric, and green chilli) is placed on the dosa surface immediately after spreading, and the dosa is folded over the filling rather than rolled. The key technique is that the potato filling must be placed before the dosa has fully crisped on one side — the heat from the tawa finishes the potato through gentle steam during the final cooking. The potato should not be made too wet (mashed-potato consistency is incorrect) — the proper masala potato is tender, slightly crumbled, with visible mustard seeds and curry leaves.

The masala dosa is a complete breakfast meal — the crisp, sour dosa against the warm, spiced potato, dipped in sambar and chutney, covers every taste register: sour (dosa), salt and spice (potato), sweet-sour-umami (sambar), fresh and cooling (coconut chutney).
