Prepare the Thecha: Roast the green chillies and garlic cloves slightly. Crush them with 1 teaspoon of cumin seeds to make a coarse paste (Thecha).
Heat the Oil: Place a pan (kadhai) on medium heat and add oil. Once hot, add mustard seeds and let them splutter. Then, add cumin seeds, a pinch of hing, and fresh curry leaves.
Sauté Onions: Add the chopped onions to the pan. Sauté until they turn translucent and lightly roasted.
Add the Spice Base: Add the prepared Thecha to the onions. Fry for about a minute on medium heat until the raw smell of garlic disappears.
Add Tomatoes & Turmeric: Stir in the turmeric powder and chopped tomatoes. Cook until the tomatoes soften. Add salt to taste and mix well.
Cook the Potatoes: Add the chopped potatoes. Sauté lightly, then cover the pan with a lid. Let the potatoes cook on low heat for about 5 minutes (they should be partially cooked).
Add Cluster Beans: Add the chopped Gavari to the pan. Mix well with the masala. Sauté for 1 minute on medium heat.
Steam Cook: Lower the flame completely. Cover the pan and let the vegetables cook in their own steam for 5–7 minutes.
Final Touch: Open the lid and check if the beans and potatoes are cooked. Sprinkle the roasted peanut powder over the veggies and mix well.
Simmer: Cover again and cook for another 5 minutes on low heat to let the flavours meld together.
Serve: Your hot and spicy Gavari Batata Bhaji is ready to serve!
