I’ve been on a quest for years for the perfect sagu recipe – the kind served with rava idli and ghee at the udupi restaurant in Bangalore. I think this might be it. The trick is to thicken the potato curry with ground roasted chana dal – it’s delicious with rice, dosa, roti or Malaysian parantha (a store bought treat – sadly too unhealthy for daily eats)
Step 1: roast and grind 1/4 cup chana dal and make a slurry with about 1/4 cup of water
Step 2: routine South Indian tampering or tadka – heat 1-2 tbsp of oil, add 1/2 tsp of mustard seeds, once they start sputtering add 1/2 tsp each of cumin seeds and turmeric, add a pinch of asafetida, 2-4 curry leaves and 1-2 dried red chilies. Add 1 tbsp of ginger and 1 tbsp of garlic and roast for 30 sec or so.
Step 3: add 2-3 peeled and chopped (into inch cubes) potatoes and salt. Cover potatoes with water and boil for 10 minutes till potatoes are cooked
Step 4: add chana dal slurry and boil for 5-10 minutes. Remove off heat. Adjust salt, squeeze a lemon to taste and garnish with cilantro and roasted cashews.
This one is easy. Knife work involves peeling and chopping the potatoes and ginger and garlic and cilantro (about 10 min). Other prep work is the chana dal powder (5 minutes). Cooking time is around 20-30 minutes but with minimal involvement after the tadka. Yep- a good week-night meal.
