Nope, no ties to the Czech Republic at all!
We just thought it would be fun to do — pick a different country/culture each year, learn about how they celebrate the holiday season, and incorporate some of those traditions and foods into our celebration. In addition to the food, we added a Czech ornament to our tree, a Czech Christmas decor item to the house, my son is getting a traditional toy on Christmas Eve, and we’re going to do a floating walnut activity they do. I drew the line at the live carp in the bathtub, though.
It’s been a fun (and educational) way to keep things interesting and fresh.
I told my husband I was going to be lazy and pick Italy so I could get by with just making a lasagna, but he wanted to be a smart aleck and say that he’d had his heart set on the Czech Republic, so that’s how we landed on that this year.
