How to make
Dissolve the yeast in a little of the milk, which needs to be slightly warm, add 1 tsp sugar. Sift the flour into a bowl and mix with it the sugar and salt. Make a well and add the milk and dissolved yeast.
Begin stirring vigorously with a wooden spatula, until you get a thick dough. Stir for a few minutes until it becomes homogeneous and hangs in thick ribbons when you lift it with the spatula. Cover the bowl with plastic wrap and leave it to rise for 1 and 1/2 hours – it has to rise and then fall.
Dissolve the baking soda in the cool water and add it to the dough, stirring vigorously. Cover again with foil and leave in a warm place to increase in volume and for bubbles to form on the surface. Heat a greased skillet on the stove and brush metal serving rings with oil.
Put them in the pan and fill them halfway with the batter. Bake for 7-8 minutes to inflate and until they turn golden brown on the bottom.
Then, remove the rings and flip the cakes over to bake on the other side.
