In large bowl combine vegetables through fenugreek. Toss vegetables until coated with spices. Using your hands squeeze vegetables and mix for about 45 seconds until softer and some liquid has released.
In small bowl mix together flour, baking powder and turmeric. Sprinkle over vegetables and mix until no longer powdery. Add water and stir until well mixed.
Heat oven to 200. Set wire rack on baking sheet. Heat 1 1/2" oil in large Dutch oven to 375.
Drop heaping tablespoons of batter into oil, cooking about 4-5 pakoras at a time. Fry until deep golden brown, about 1 1/2-2 minutes per side. Use slotted spoon to remove and place on wire rack. Place baking sheet in oven to keep warm while cooking remaining batter.
Serve warm, with chutney or raita.
