Pour the dosa batter into the pan and spread evenly. Top with mashed potato, coriander, curry leaves, and cumin seeds. Sprinkle salt to taste.
Cook for 1-2 minutes until the bottom is golden brown.
Flip and cook the dosa for another miniature and press down gently with a spatula.
Repeat the process with the remaining batter and filling ingredients.
Serve with sambar and chutney. You can also add butter on the top.
