I like
this site, with very interesting recipes and infos about their culinary culture.
My personal favourite, I am not sure what I would call it but it is my recreation of something I had at a Russian restaurant in London. It is very simple to make and absolutely delicious.
Slice up the mushrooms (regular white will be fine but more flavourful types will be even better)
Finely chop up the onions.
Sautè the mushrooms with a little butter, s&p.
When they are cooked well, with onions at the point of being caramelized, add some vodka and a piece of bayleaf, let it simmer for 10-15minutes.
Stir in sour cream and chopped flat leaved parsley, and heat it up (but not to the boil) thoroughly.
This was served in a deep "pot pie" style (on a deep jar covered with a crusty bread on top), it is delicious by themselves without the topping as well, or as a condiment for your pasta.
I would love to try blini and pirozhki one day, if I could find a recipe that I can trust upon. I haven't as yet though...
