I apologize in advance for the poor quality photo.
So, melt the margarine. Beat eggs with sugar and a pinch of salt.
Add sour cream and soda (0.5 tsp), quenched with vinegar, mix well.
In our mixture pour melted margarine, only margarine should not be hot.
Add flour. In the original it was stated flour 3 cups (200 grams), I have a 150 gram glass and it took me 5 cups, the dough should approximately 600-750 grams of flour, more depending on the variety.
Mix well with a spoon, and then knead the dough with your hands. The dough turns out to be very gentle, soft, which is already nice to knead. Not tight and to the hands should not stick. Divide the dough into 6 parts.
Each part is rolled out in the form of a circle (I got a semblance of a circle) and cut into 8 triangles. Uploaded on every triangle condensed milk and, on desire, can be nut.
Twist the bagel, only a good pinch the edges to condensed milk did not run away. We get such cookies-bagels, dip them in sugar (I decided to diversify and dipped in cinnamon, but it does not look very nice, with sugar more beautiful) and spread on a baking sheet, covered with parchment. The parchment preferably a little butter, I just wasn't lubricated and they have me a little stuck.
Send our cookies in a preheated 200 degree oven for 30 minutes. Although, here is a look at the oven. The cookies should be browned a little. Here such happened with me (in the context). And I really like that they do not take much time. It took me 1 hour. Bon appetit!
