Peel the cooked potatoes and mash it well. Add whisked curd in to a bowl. Now add mashed potato to whisked curds and mix it well.
Heat a seasoning pan adding all the ingredients in the "seasoning ingredients" list one ofter the other, once the mustard seeds splutter, add chopped green chillies and ginger. Stir for while and switch off. Add salt and seasoning to potato-curds mix of step 1.
Add dissolved asafoetida and mix well. Add whisked curds or buttermilk as per the consistency desired. I like little thicker version of potato raita.
Aloo raita is ready....Serve it with steamed rice as side dish.
Note:
Potatoes should be cooked till mushy, so that it can easily blend with whisked curds.
Don't skip asafoetida, that gives nice aroma to raita.
