Start preparing the dough. Add a pinch of salt to the eggs and beat with a mixer at maximum speed. Reduce the speed, continue beating and add sugar. Beat until white foam. This will take about 1 minute.
Add margarine and flour. Add all the margarine to the egg mixture, stir until smooth. Add sifted flour in 2-3 stages. Mix well each time, avoiding lumps. The finished dough should be smooth and glossy. Liquid, like low-fat sour cream. Cover with cling film or a lid and let sit for 10 minutes.
Preheat the waffle iron. When the green indicator lights up, you can bake. Pour 1-2 tablespoons of dough onto the surface. The amount of dough may vary slightly, but do not pour too much at once, otherwise it will run out of the form.
Prepare the waffles. Bake for 1 to 5 minutes. To check if they are ready, open them slightly to see if they are browned or not. After cooking, remove the waffles with a silicone spatula and roll them into tubes. This must be done quickly, as they will harden instantly and will only crumble afterwards.
