Potato curry, with a dash of lime juice

(Authentic Andhra way - my favourite curry from my grandmom's kitchen)

Ingredients:

Potatoes - 3-4 (big)
Lime juice - 2/3 tbsp
Oil - 1/4 cup
Chana dal - 1 tsp
Urad dal - 1 tsp
Jeera (cumin seeds) - 1 tsp
Rai (mustard seeds) - 1/2 tsp
Green chillies - 4 (chopped into 1" pieces)
curry leaves - a bunch
salt - to taste
Turmeric powder - 1/4 tsp
Chilli powder - 1/2 tsp

Method:

Pressure cook potatoes. Cool, peel, and mash them and keep aside. In a kadai (pan), heat oil, add chana dal. After it is fried a little, add urad dal, jeera, rai, green chillies and curry leaves to the oil.

Now, add the potato mash to the seasoning, and put salt, turmeric and chilli powder to it. Cook it on low flame for 5 mts or till potato has a semi-fried look.

Remove from the fire, and leave it to cool for 10 minutes. Add lime juice and serve with rice.
