Soak the chickpeas in a bowl filled with water for 12 to 24 hours.
Drain. Blend with the peeled onion in pieces in a food processor, using the "S" blade.
Add herbs, chopped without stems, spices, salt, bicarbonate of soda and chickpea flour and blend to obtain a smooth mixture.
Pour into a clean tea towel, fold over and "squeeze out" to express as much juice as possible, and dry out the dough.
Pour back into the food processor and blend to a fine paste.
The dough remains grainy and is not very sticky, this is normal.
Form 20 balls between the hands, pressing well, several times, so as to obtain balls, well rounded, which hold and place them on a plate covered with baking paper.
Lightly oil with a brush.
Bake for 10-15 minutes at 180°C.
Serve with lemon tahini sauce or other sauce of your choice. Perfect for wraps, sandwiches, aperitifs...
