In a mixing bowl, whisk together chickpea flour, water, olive oil, salt, and ground cumin (if using) until you achieve a smooth batter.
Allow the batter to rest for at least 30 minutes or longer for better flavor development.
Heat a non-stick skillet or cast-iron pan over medium-high heat.
Add a bit of olive oil to coat the bottom of the pan.
Pour a thin layer of the batter into the hot pan, swirling to spread it evenly.
Cook for 3-4 minutes on each side or until the edges are crispy and golden brown.
Repeat the process with the remaining batter.
Garnish with freshly ground black pepper and chopped herbs.
Slice into wedges and serve warm.
