Looks nobody noticed yet, or didn't pay attention.
Do you remember the file with Bogdan Khmelnitsky letters Putin gave Tucker?
Now think - why is it so thick and heavy? Copies of all Khmelnitsky correspondence could not be so thick and heavy.
What else was in that file?
Pirogi is too large even for this file, they are different from Polish pierogi and could not be easily flattened. You had to choose Russian pancakes. But I didn't noticed a jar of honey, varenie (jam), sguschenka (sweet condensed milk), caviar or pickled mushrooms which are inseparable from Russian pancakes. :)
