Both of my maternal grandparents were from Czechoslovakia. Grandpa came as a 2 year old in 1897. Grandma came as a teenager along with several family members in the early 1900’s. Both stayed at Ellis Island while they were processed, and both of their families lived in Brooklyn. Many years apart. Not all of Grandma’s family came (large Catholic family).
Sauerkraut was a staple, and Grandma passed down her handwritten recipes to her children, and then to her grandchildren, through the magic of home printers. (Do you want to know what COOL looks like? It looks like my Grandma’s handwritten recipes in broken English! 😍)
Perhaps you should post your Grandmothers sauerkraut recipe. It might be interesting!
