Heat an iron tava and once it is hot maintain low medium flame. The uthappam will be thick and fluffy, so they need to cook in low-medium flame.
Pour a small ladle full of idli batter and spread very lightly if required. Drizzle some oil over the edges and on top. Sprinkle the topping you chose. Drizzle some more oil. Cover and cook for 2-3 minutes. This ensures a nice crispy crust. For cheese uthappam cover and cook till the cheese melts.
Arrange in a plate and serve 7 taste uthappam hot.
Notes
1.You can even normal sized uthappam instead of mini ones. 2. Vary topping as per taste 3. You can use ghee instead of oil for onion and podi uthappam.
