Regional, ethnic or just family custom?
Here in South Florida with the Hispanic influence, we usually eat 12 grapes at midnight. And in my family we always have a New Year's Eve meal of appetizers with no main. So tonight we'll be having camarones al ajillo, spanakopita triangles and miniature blintzes.
When I cook for larger groups, I always include bittersweet double chocolate mini tartlets that are super easy to make, but since it's just DH and I for dinner (going out to parties after dinner) this will be the first year w/o the tartlets in quite a while.
