Add the arbi and fry till they get a little browned.
Add 2 cups water.
Now add the thin curd mixture.
Keep stirring often or the curd will split.
Bring to a boil and then simmer for 15 minutes.
Add salt.
Garnish with chopped mint leaves and serve dahi arbi hot with warm rice or soft phulkas.
Notes
The same recipe can also be made with whey instead of thin curd.
Stirring the curd mixture often once its put on fire is very important. If you don't stir then the curd will split into shreds in the curry. So keep on stirring continuously till the whole mixture reaches a boil. Then lower the flame and let the curry simmer. When the curry is simmering, stir occasionally.
If making for fasting, then add rock salt instead of regular salt
