At this time, we will do the stuffing. Everything went wrong here: at first I wanted to make buns with a bright pumpkin filling, but after adding sugar, I found that the puree turned out to be too liquid. After thinking about it, I added cottage cheese rubbed through a sieve, which gave the filling the desired consistency.
And now in order: add sugar, cinnamon and half of the beaten egg to the pumpkin puree. Then rub the cheese through a sieve and mix with the filling. Try for sweetness, if the cottage cheese turned out to be too sour, add another 1-2 tablespoons of sugar.
