Pork, sauerkraut & dumplings, or PSD as we sometimes call it.
German chocolate cake
Herring (only at Christmas, thankfully...not my favorite!)
Food is something my family uses to keep our heritage and traditions alive, but I never stopped to think about how important those foods are to me until I started to prepare them for someone who was not family (aka...my daughter's boyfriend.) In our family, the little kids are encouraged and persuaded to taste, eat, and fall in love with these foods because "It's your heritage," as my brother-in-law says.
We are Polish, my husband's family is German, but my favorite aunt is Italian, so there are a few of those foods mixed in as well.
What foods help make you 'you'?
