I had big plans for that jar of sauerkraut I made earlier this month. Plans involving plates of grilled sausages, deli-style reubens, and tangy late-summer slaws. But at the very top of my list were pierogi. I love dumplings in all forms, but these piping hot, chewy pockets of potato and cheese have held a special place in my heart ever since a Russian exchange student first introduced me to pierogi in high school. They are so satisfying served with nothing more than melted butter and a sprinkle of salt. They also freeze beautifully, so stockpiling them in the freezer for an easy comfort food meal on a busy night makes total sense.
