My Mom's cousin Grace made this years ago and I've always wanted to make it. I did back in 2005 and a few times since then. I love the combination of flavors of the caviar and sour cream.
1 large round bread (approx 24 ounces)
2 cups sour cream (maybe a little more, depending on the size of the bread)
3 boiled eggs; yolks and whites chopped separately
1/2 cup chopped red onion
Black lump caviar
Carefully carve out the center of the bread, keeping approximately 1/2" thickness. Cut the bread, which has been removed, into cubes. Cube the baguette.
Layer in the bread the sour cream, and then the caviar. Place the egg whites in a ring at the outer edge of the bread, followed by the yolks, and red onion.
Serve with the cubed bread.
