Pancakes for terrine we need thin, elastic, so as not to tear. Therefore, I will bake classic pancakes according to an ancient recipe completely without baking powder and soda and with milk. The only thing that will break the classics is that I will add vanillin to the dough, because I will also add vanillin to the filling. Preparing everything for the test. Break the eggs and add sugar, vanilla, and combine with a hand whisk. The milk needs to be warmed up. Pour half the volume of milk into the eggs. Sift the flour and carefully combine it with the same whisk.
