Step 2: How to Make Dosa Batter:

First wash and soak rice and split black grams overnight and in morning grind it together with very less water.
Rest it for 5-6 hours to ferment.
Now add salt into it and mix it well.
Keep the batter aside.

Step 3: How to Make Masala for Dosa:

First boil, remove the skin and cut the raw bananas into medium sized pieces.

Now take one medium sized kadai/pan, put the oil, once it's hot as mustered seeds.

One mustered seeds spluttered, add cumin seeds and asafoetida.

Add green chillies and curry leaves and mix it well.

Now add raw banana pieces, add turmeric powder, red chilli powder and salt and mix it well.

Cook for another 8-10 mins.

Switch off the gas and remove it from heat and place it in a bowl.

Keep it aside.

Step 4: How to Make Sambhar:

First pressure cook the split red grams with tomatoes and some water, place the bottle gourd as well in pressure cooker in another plate.

Allow it to be cooked till 3 whistles done.

Once it's at room temperature, open the pressure cooker, add all dry masala ingredients and blend the dal with blender.

Cook out on medium flame for 5 mins.

Now do tempering using all the ingredients listed in 'For Tempering' and pour it on sambhar.

Your sambhar is ready, keep it aside.

Step 6: How to Prepare Masala Dosa:

First heat the non-stick tava and sprinkle water on it when it's very hot and then wipe it properly.

Now take one ladle dosa batter which we prepared in Step 2, and spread it gently on tava.

Sprinkle oil on edges.

On half of the dosa, place the masala we prepared in Step 3, and add butter or purified butter if you like and using turned turn the other half of dosa.

Serve as it is or cut into pieces if you like, with hot sambhar and chutney we prepared (in Steps: 4 & 5)

It's so delicious if we serve it with green chutney!

Enjoy your meal!
