Preparation
What else is there to do when you have blueberries at home, and simply eating them would be too easy :)? The result was vareniki! These vareniki are good with blueberries and other fillings too, but let's take things in order...
Ingredients for the dough:
wheat flour - 2-3 cups(depending on how many berries or how much filling you have) baking powder - 1 tsp. or slaked baking soda - 1/4 tsp. salt - 1/2 tsp. sugar - 2-3 tsp.(if the filling is sweet, such as berries; for a filling like potatoes with mushrooms, omit the sugar) room-temperature water - about 1-1,5 cups (it all depends on the flour) eggs - 2
Preparing the dough:
First, mix the dry ingredients, add the eggs and water, and knead the dough as you would for challah.
Then you can start making the vareniki without letting the dough rest. Remember to dust everything with flour (your hands, the work surface, the dough, and the cutter—I used a drinking glass as a cutter).
Divide into 5-6 pieces, shape them into balls, and set them aside. Then roll each one out into a flat round, cut out circles with a glass, and add the filling, but don't overdo it, so the dough doesn't stretch too thin and is easy to seal :).
Filling options:
Blueberries - for 350 g, about 3-4 tsp. sugar(you can leave it out)
Cherries - for 300 g, about 5-7 tsp. sugar(adjust according to the fruit; if it's sweet, reduce the amount of sugar)
Farmer's cheese - for 0,5 kg, about 2-3 tbsp. sugar
Potatoes with mushrooms - boiled potatoes - about 5-6 large potatoes, 200 grams of any mushrooms (we used button mushrooms), a small onion (optional); sauté the onion and mushrooms (in that order), mash the potatoes, and mix the mashed potatoes with the mushrooms and onion, adding salt and pepper to taste, but be generous so the filling isn't bland (I recommend pan-frying savory vareniki, though they're also good boiled).
Enjoy making them, and enjoy your meal!
