Russian Apple Pancakes

Directions

1. 1
   Place the milk in a medium bowl and stir in the yeast, then stir in the flour and 2 tablespoons sugar.
2. 2
   Stir for 1 minute, then set aside for 30 minutes to 2 hours, whichever is most convenient.
3. 3
   When ready to proceed, add the egg, salt, and melted butter and mix thoroughly.
4. 4
   Cover with plastic wrap and let stand for 6 to 8 hours, or overnight.
5. 5
   (If keeping the batter for longer than 8 hours, or if the temperature is very warm, refrigerate the batter until 2 hours before using.)
6. 6
   The batter should be bubbly when ready.
7. 7
   Before cooking the pancakes, decide which method you wish to use to caramelize the pancakes: If using a broiler, turn on the broiler and use an ovenproof 8- to 9-inch skillet.
8. 8
   Otherwise, put out two heavy 8- to 9-inch skillets.
9. 9
   Heat a heavy 8- to 9-inch skillet over medium heat, and melt 1 tablespoon of the butter.
10. 10
    Add half the apples and saute until soft but not brown.
11. 11
    Spread the slices well over the bottom of the pan, sprinkle on 1 tablespoon sugar, and lower the heat to medium-low.
12. 12
    Pour on a scant 1 1/2 cups batter and spread it to the edges of the skillet.
13. 13
    Cook until the top is spongy and dull, no longer liquid and shiny, about 5 minutes (be patient).
14. 14
    Meanwhile, if using two skillets, butter the other one lightly and place over medium-high heat.
15. 15
    Sprinkle the top of the pancake generously with cinnamon sugar (about 1 tablespoon).
16. 16
    Place the skillet under the broiler and broil until the cinnamon sugar melts, about 1 minute; or flip the pancake into the other skillet and cook for 1 to 2 minutes.
17. 17
    Transfer the pancake to a platter apple side up.
18. 18
    Repeat with the second pancake.
19. 19
    Serve hot.
