Prep the Pumpkin: Quarter the pumpkin, scoop out seeds, and peel the skin. Cut the flesh into large, uniform chunks.
Load the Pot: In a pressure cooker (or Instant Pot), add the pumpkin, carrots, onion, celery, ginger, garlic, chilies, cilantro stems, and raw cashews.
Add Spices: Toss in the cinnamon stick, bay leaves, cloves, and a generous pinch of salt.
Water Level: Pour in just enough water to barely cover the vegetables. Do not over-saturate, as the vegetables will release their own juices.
Pressure Cook: Secure the lid. Cook on high pressure for 2 to 3 whistles (approx. 8–10 minutes). Allow the pressure to release naturally.
De-Spice: Open the lid and carefully remove the whole cinnamon stick, bay leaves, and cloves.
The Power Blend: Transfer the cooked mixture and liquid to a high-speed blender. Blend on high until the soup is a vibrant, silky-smooth purée.
Fine Texture: For a restaurant-quality finish, pour the blended soup through a fine-mesh sieve into a clean pot.
Adjust & Simmer: Bring the soup to a gentle simmer. Add warm water if the consistency is too thick.
Final Seasoning: Stir in the fresh lemon juice and black pepper. Taste and add honey if the pumpkin needs a sweetness boost.
Serve: Pour into warm bowls and enjoy immediately while steaming hot.
