1. In a saucepan, boil 6-8 cups of water with 1/2 tsp salt.
2. Wash cauliflower in running water. Cut them into tiny florets.
3. When the water starts boiling add cauliflower florets and remove from flame.
4. Let it soak for 3-4 minutes (5-6 minutes for soft florets).
5. Strain water using a colander or a strainer.
6. Place a skillet/pan and let it heat up a bit.
7. Add oil, when it is hot add cumin seeds and let is splutter.
8. On a medium flame, add finely chopped onion and saute until it becomes translucent and turns light golden brown.
9. Add quarter teaspoon salt for faster browning.
10. Add finely chopped tomatoes and saute for 3-4 minutes or until it becomes mushy and blends with the onion.
11. If it sticks to the pan don`t worry.
12. Add cauliflower florets and saute for a minute.
13. Add some salt to it and saute for few more minutes.
14. You will see that those florets starts leaving out water/moisture.
15. If it does not shed water and sticks to the pan add a few tbsp of water to keep it moist.
16. Now add ginger garlic paste and saute for a minute.
17. Add coriander powder, chili powder and mix well.
18. Adjust salt/chili powder as per your taste.
19. Simmer and saute for few more minutes until the raw smell of masala disappears and water evaporates.
20. The final masala should be dry.
21. Remove from flame, add chopped coriander leaves, stir and close it with a lid to allow the flavours mingle with each other.
22. After 15-30 minutes, heat a tawa/griddle.
23. Add a few drops of water and you will see that it sizzles or dances on the tawa. Let it evaporate.
24. On a medium flame, pour a laddle full of dosa batter and spread it in a circular motion.
25. Do not make it thin, rather spread it to uthappam`s thickness or a little lesser than that.
26. Using a spatula or your hands spread the dry cauliflower masala on top of the dosa (when the batter on top of dosa is still wet).
27. Gently press it with a spatula and add a few drops or quarter tsp of oil around dosa and on top of it.
28. Ensure that you do this quickly or dosa might get cooked and the masala won`t stick to it.
29. When the bottom side is cooked, gently flip it and let it cook on the other side.
30. This helps the spiced florets to get a little charred and it tastes great.
31. Slide it on to a plate and serve hot with chutney or sambhar.

Notes:
If you are not comfortable flipping dosa with masala on top, close the dosa with a lid and let it cook little longer (appam style). Then, carefully slide it to a plate.
With a little practice and patience you can improve your dosa making skills.
While serving it to kids or to enhance the flaovor you can use ghee while making dosas.
