Start by roasting the sooji along with one teaspoon of cumin (jeera) until it's fragrant on a medium-low flame in a pan.Do not burn or brown the sooji from the bottom, so be careful. Remove it into a clean, dry bowl or plate.**Note: You can do this step of roasting sooji in advance and save time for busy mornings. Add oil to a heavy bottom pan, add mustard seeds, chana dal, urad dal, and cashew nuts, and saute for 1 minute until they change color.
Next, add chopped ginger, green chilies, asafetida, and curry leaves. Saute another 20 secs.
Next add water, milk and let the water come to a boil. Do not add salt directly at this stage; milk will curdle.
Once the water & milk comes to a boil, add salt, and start adding the (roasted sooji + jeera) a little at a time. Stir continuously after each addition in one direction with a spatula to avoid lumps.
Then cover the pan with the lid and set the heat to low. Let it remain like that for 2-3 mins until the moisture gets absorbed. Turn off the heat.
Remove lid, add lemon juice, coriander leaves, and two tablespoons of ghee. Ghee is optional but recommended. Mix well.
Serve hot with coconut chutney, pickle, and sambar.
