Grate about 5 medium potatoes coarsely, then put them in a tea towel to dry for 10 minutes.
Lightly mash the peas with a fork.
Mix all ingredients in a big bowl. You should get a slightly sticky mixture. For a non-vegan version, you can add an egg, beaten.
Het some oil a large frying pan and, using a spoon, add drops in the pan, slightly pushing them down. After a couple of minutes turn them over with a spatula and cook until golden and crispy.
Transfer them to a plate lined with paper kitchen towel, then repeat with the remaining batter.
Serve warm or at room temperature.
