For the dough, mix the flour with cane sugar, sea salt and 90 ml of water to form a smooth dough. Crumble the cornflakes finely. Cut the tofu into 1 cm thick slices, then cut into a nugget shape with a knife. Turn the nuggets first in the batter and then in the corn flakes.
Heat the vegetable oil in the deep fryer or a small saucepan. The oil is hot enough if you stick a wooden stick into the fat and bubbles rise from it. Fry the nuggets in it for about 3 minutes and drain on kitchen paper.
If you don`t want to deep-fry the nuggets, you can fry them in 80 ml of vegetable oil in a pan on all sides until they are light golden brown.
