Mix zucchini, onion, cumin seeds, turmeric, garlic-jalapeno paste, baking powder and yogurt in a large bowl.

Add in the AP flour and water to make a thick batter and season the batter with salt.

Heat oil in a skillet over medium-high heat.

Scoop a ladle-full of batter into the hot skillet and fry until golden brown on both sides (should take about 2 minutes per side).

Serve with a dollop of yogurt or any topping of choice.
