Trim off and discard the root ends and any dried or browned parts of the leek greens. Cut the leeks lengthwise in half and then slice them crosswise into bite-sized pieces; set aside.
In a separate bowl, mix the flour with water. It's best to use a whisk to dissolve any small lumps of flour.
Stir in the salt, black pepper, curry, or turmeric powder.
Ensure the seasoning is well combined with the batter; set aside.
Coat the bottom of a large skillet with two tablespoons of olive oil and heat over medium heat. Stir in the leeks—cook and stir for 5 minutes, or until tender—season to taste with salt and pepper.
Transfer the sauteed leeks into the reserved batter and stir until everything is well combined.
Add one tablespoon of chickpea flour to the mix to thicken the batter.
Coat the same skillet over medium heat with one to two tablespoons of olive oil—either swirl the pan or use a spatula to divide the oil to coat the bottom of the pan.
When olive oil is shimmering, drop ¼ cup of the veggie cake batter at a time and flatten slightly with the backside of a spoon to form a pattie. Leave enough space in between the veggie cake patties, and try not to crowd the pan.
Cook first for 3 to 5 minutes on one side. Ensure that they have a solid bottom and are sufficiently browned on one side before you turn them around.
Then cook for another 3 to 5 minutes on the other side until golden brown with a crispy exterior. Transfer the veggie cakes to a plate.
Repeat until all batter has been used—only add more oil if needed. Enjoy!
