Preheat air fryer to 360°F for 3-5 minutes and spray the basket lightly with oil. In a large bowl, mix gram flour, rice flour, cumin seeds, turmeric, garam masala, and salt.
1 cup gram flour, 2 tablespoons rice flour, 1 teaspoon cumin seeds, 0.5 teaspoon turmeric powder, 1 teaspoon garam masala, 1 teaspoon salt
Add water gradually to the bowl and whisk for 3-5 minutes until the batter is smooth and thick enough to coat the back of a spoon without dripping. Let the batter rest for 10 minutes.
0.5 cup water, 1 cup gram flour, 2 tablespoons rice flour
Toss the thinly sliced onion, julienned potato, chopped spinach, and minced green chili into the rested batter. Mix until vegetables are evenly coated.
1 medium onion, 1 medium potato, 1 cup spinach, 1 green chili
Scoop 1.5-inch portions of the batter-coated vegetables and place into the air fryer basket, leaving about 1-inch gaps between pakoras.
Air fry the pakoras for 6 minutes. Then spray them lightly with oil, flip each pakora gently, spray again, and cook for another 6 minutes until golden brown and firm to the touch.

Check doneness by pressing lightly; pakoras should feel firm, not squishy, with no raw batter taste. Serve immediately while crisp.
