I'm Russian, and this recipe has been handed down from my grandma. They taste delicious, and are a great comfort food (or any other food).
I'm Russian as well and make pirozhki pretty much the same way. Here is what I do differently: I rub shredded cabbage with garlic salt in a large pot, and then pour boiling water over the cabbage covering completely. Boil the mixture until soft, usually around 15 min. Take the pot off the heat, drain the cabbage and return it to the pot, add spices, .5 to 1 spoon of butter(I use Smart Balance butter or other butter made with olive oil), and the eggs. Also, after pinching the end together, I turn piroshok so that the pinched ends are on the bottom rather than on the side. It helps to keep not-so-well-pinched pirozhkis closed during baking and creates a nice symmetric shape. After placing the pirozhki on the baking sheet, I let the dough rise just a little. Right before baking, I brush them with beaten egg yolk for glowing smooth look when ready. Yumm! - 02 Jan 2008 (Review from Allrecipes US | Canada)
I love this recipe, just like all other russian children, I grew up eating these! I also fry onions in olive oil until they are golden and sometimes a little bit burnt and add them to mashed potatoes, if you use the oil from frying the onions then you really dont need to add milk or butter whem mashing the potatoes. Another filling is sour cherries, i don't think anyone mentioned that, from what i know the traditional fillings for pirozhki that you can buy at a russian store is meat, potatoes, cabbage, or cherries, sometimes i'll also add 18% fat cottage cheese with a little of my favorite (or whatever i have in the pantry) jam inside. - 10 Dec 2009 (Review from Allrecipes US | Canada)
This recipe is wonderful and a real crowd pleaser. My Russian Mother in law loved these. I recommend brushing them with egg yolk just before putting them in the oven for that professional, golden color and shininess. Also, it is very traditional to add cooked white rice with the filling or mashed potatoes. The salt and pepper are key in the filling; too little is very bland. - 21 Nov 2009 (Review from Allrecipes US | Canada)
