I tend to bring desserts. A common one is key lime pie, when I can get real key limes. I haven't seen those for sale in Czech Republic. Only regular limes. They were seasonally available for purchase in New Jersey. I think key lime pie is far more common in the US, anyway. As are pies, in general. My side of the family is the typical pie loving American family. Every holiday meal included a variety. Four or five.

Savory? Perhaps my potato and kohlrabi au gratin. That's always a hit. It goes with most holiday main courses.

What aren't you going to do this month that you usually do?
