Heat ½ cup oil in a pressure cooker. Add 1 tbsp cumin seeds, 1 tsp ajwain, ½ tsp hing, 4–5 dry red chillies, 1 inch cinnamon, 2 bay leaves, and 3–4 cloves. Sauté well.
Add the ground green paste and ½ cup green garlic. Sauté for a minute.
Add 100 g or 1 cup surti papdi, 100 g desi valor papdi, 50 g green tuvar, 50 g green peas, 50 g green vaal, and 50 g green chana (jinjara). Sauté on a medium flame until slightly soft.
Add 1 tsp turmeric powder, 1 tbsp red chilli powder, 1 tbsp coriander powder, 2 tbsp undhiyu masala, and some hot water. Sauté until oil separates from the sides.
Add ¾ cup tomato puree and salt. Sauté well.
Add 2–3 tbsp undhiyu masala and mix properly.
Mix the remaining undhiyu masala with the fried vegetables and layer the masala-coated vegetables over the papdi mixture in the cooker (refer to the video).
Add 1 cup hot water from the side of the cooker. Do not mix.
Cover with the lid and cook on a medium flame for 1 whistle.
Once the pressure releases naturally, open the lid and add ½ cup tamarind water and 3 tbsp jaggery. Mix gently.
Add the stuffed brinjals, green chillies, and muthiya. Add 1 cup hot water. Do not mix. Cover and cook on a low flame for 5–7 minutes.
The muthiyas will absorb the water and turn soft. Undhiyu is ready.
