Dissolve yeast in 100 g of warm milk, 1 tbsp. l. sugar, 1 tbsp. l. flour. Put for 20 minutes in a warm place.
Sift the flour, add salt, the rest of the milk, the rest of the sugar, the dough. Knead. Add oil and knead well - the dough should be elastic, non-sticky. I kneaded in HP in the "Dumplings" mode.
Put the resulting dough in heat for 40 minutes. It should fit at least 2 times.
For the filling: boil rice in proportions to water 1: 1 so that it is half cooked. Chop the onion very finely and fry in butter until golden brown. Cut the fish into 1-2 cm cubes. Mix all the ingredients for the filling, salt and pepper.
Heat the oven to 180°C. Divide the dough into about 10-11 pieces. Roll each into a circle, put 1 tbsp in the middle. l. or on the eye of the filling.
Carefully close up, starting from opposite edges of the pie, leaving a hole in the middle 1-2 cm in diameter.
Put on paper on a baking sheet, let stand for 15 minutes, grease the top with yolk.
Bake until golden brown. It took me about 30 minutes. In the process, it would be nice to pour a spoonful of broth into the filling.
