You ALWAYS have sauerkraut (hapukapsas) and black pudding (verivorstid) at an Estonian Christmas table. I've written about sauerkraut before, here's a picture of a pan full of 2 different types of black pudding or blood sausages before roasting.
And here's a picture of my first Christmas meal in 2005, at my auntie Vaike's place - a week before Christmas actually:)
Sauerkraut, black and white pudding (same thing, one with and the other without blood), potatoes and a really delicious chunk of roasted wild boar (hunted my my cousin's husband). Yummmmy..
