In a large bowl combine lentil flour, salt, chaat masala, amchur powder and baking soda.
Add water slowly and whisk until a smooth medium thick batter forms.
Wash and dry the spinach leaves well so the batter sticks properly.
Dust the spinach leaves lightly with dry flour.
Dip each spinach leaf into the batter and coat evenly.
Line the air fryer tray with parchment paper and arrange coated spinach leaves in a single layer.
Preheat the air fryer to 180°C | 365°F for 3 minutes.
Air fry the coated spinach leaves for 6–7 minutes until lightly crisp.
Remove and cook remaining batches the same way.
Return all batches to the air fryer and cook for 2 more minutes to make them extra crispy.
Transfer crispy spinach leaves to a serving plate.
Top with diced boiled potatoes, tamarind chutney, green chutney, pomegranate seeds and chaat masala.
Serve immediately while the palak patta chaat is crispy.
