Blintz are Russian crepes, and there is a saying that the first one is always a ball of half-cooked dough. There is an objective, physical reason for it - I do not remember exactly what it is since I cannot make crepes (the range in my rental unit is much older than I am and it is an electric range with the uneven burners, so crepe making is completely out), but more or less there is some process that goes on when the butter and dough for the first crepe are on the pan that paves the way for the success with subsequent crepes. The first one is a ball of half-cooked dough but the subsequent ones are thin, round, bubbly crepes everyone loves to eat. Without that first fiasco, the successful crepes cannot see the light of day.
