It so happens that in your search for the perfect pancakes, you try recipe after recipe and suffer another fiasco. Lumpy turns out not only the first pancake, but all subsequent ones. You sin on the recipe and try a new one, but the situation repeats itself. Perhaps it's not about the proportions and ingredients, but the fact that you are making a number of common mistakes.
If, regardless of the recipe, every time you get your pancakes "rubbery", with a chewy, viscous texture, then perhaps you are trying too hard when kneading the dough. Of course, annoying lumps are evil, but if you achieve a perfectly smooth dough, then too much gluten will be released if you mix too much. It is she who makes pancakes sticky, like chewing gum. It is enough to achieve a homogeneous dough. The easiest way to do this is to separately beat the liquid ingredients, and then add the sifted dry ingredients to them in a thin stream.
Are the pancakes burning? If you fry them in butter, the solids may remain in the pan over and over again. It is they who burn, leaving scorch marks on the pancakes. To avoid them, fry in ghee or vegetable oil. Slices of berries, fruits or chocolate chips added by you to the dough can also "burn". In this case, add the "hot" after you have poured the dough into the pan.
The dough is bubbling in a bowl and in a skillet, but the pancakes themselves are dense? Perhaps because you did not wait for the bubbles to burst. To make the pancake look delicate, it is necessary to turn it over when "holes" appear on it.
Pancakes can stick to the frying pan if it was not initially heated enough or there is little oil on it. Then, when you turn them over, they will, of course, break. The pancake can also break when you pry it with a too short spatula. Use a long, narrow spatula to turn the pancake over and it will remain intact.
The first pancake, which turns out to be lumpy, seems to have been specially created in order to taste how tasty the rest of the pancakes will turn out to be. Do not throw it away, but taste it! It is not too late to add salt, sugar, pour in a little warm liquid if the pancakes are too dense.
