Homemade crepes filled with meat filling. A classic Russian/Ukrainian recipe.
In a bowl of an electric mixer fitted with a paddle attachment, mix together 10 eggs, 4 tbsp sugar, 1 tsp salt, and 3 cups flour until all flour is incorporated and the batter looks smooth, with no flour lumps, about 2 minutes.
With the mixer still running on low speed, start adding 4 cups milk, stopping and scraping the bottom of the bowl, until full amount of milk is added. Once the batter looks smooth add 50 milliliters oil and mix for another minute or two. Cover the batter with plastic wrap and let rest in the fridge for about 30 minutes (it can easily stay in the fridge for a couple of hours if needed), letting the flour fully absorb the moisture. (Meanwhile, you can prepare the filling)
