As an aside, I am of Eastern Euro & Russian descent (4 immigrant grandparents) and many of these recipes are similar to one's I make and remember and a couple - the Babka & the jelly doughnuts - are foods from my childhood that I have no authentic recipe for. They sound delicious and remind me of my childhood & Baba and I can't wait to try them!! Thanks!!
Bless you, I have a bushel of authentic ethic recipes many of my favorites are Kosher.. just ask and they could be yours.. :)
