Start the day before, or atleast early in the day to serve in the evening.
The dry ingredients need time to soften, and get friendly. Mix all
ingredients and refrigerate over night.

Carve out the bread to make a bowl, saving the bread to dip into the
sauce.

When ready to serve, put the dip inside the bread, arange the bread pieces
around the bowl. When the pieces are gone, slice, rip, or tear the
remaining crust and eat.

We had a bakery in Baltimore that made a great Sweedish/Onion Rye, although
that was the name on the bread, they claimed that there was nothing special
about it. I have served it with plain store bought rye, the round loaves
and with my own home made rye.
