If it's okay to ask, what is pirozhkis usually filled with?
Well, there are thousands of recipes of pirozhki.
The most common fillings are:
- Mashed potatoes;
- Chopped meat;
- Onion & eggs;
- Quark (russian tvorog);
- And many others ^^
Generally, you can fill pirozhki with whatever you want.
Personally, I love cheese and chiken & mushrooms.
P.S. BTW, in Russian “pirozhki” is a plural form of a word. The singular form is “pirozhok”. ^^
And sometimes people, who are in love with each other, affectionately call their partner as “ My pirozhok (Мой пирожок)”. Parents and grandparents also call children in such way.
