What traditions do you have that your grandparents did, your parents did and now you do?
For my family it is what foods we prepare and enjoy. Croquet's, Olie Bollen, boterkoek, and more, are treats eaten mainly between Christmas and New Years. (sometimes we cheat and have them in the summer!) For us they are an important part of our celebrations. The recipes I use have been passed down from my Oma, and I am sure from hers before that.
So share what is important to your celebrations.
