Popu or Seasoning

Most of the Andhra recipes call for Popu or Seasoning to enhance the taste of the recipe or sometimes it becomes the basic ingredient. It is widely used to enhance the taste of many recipes like dals(pappus),sambar,pachchadis and popu becomes basic ingedients for many pickles too. Most of the time the ingredients are same .The basic Popu recipe I follow for most of my recipes is:
Ingredients:
1 tsp oil
2 dry red chillies(endu mirapakayalu)
1 tsp urad dal(minapappu)
1/2 tsp mustard seeds(avalu)
1/4 tsp cumin seeds(jeelakarra)
curry leaves 4/5
hing
Method:
To make the popu,heat oil and add all the ingredients and fry till mustard seeds splutter and dals are in light brown colour. Add hing and curry leaves at the end to retain the nice aroma for a longer time and now,add this to the required recipe
