DULUTH, MN (KDAL) - The famous candy-making Grambsch family of Loyal, WIsconsin returned to the Depot in Duluth on Saturday to make their old fashioned candy again for one day only.  They donated their candy making equipment to the Depot 30 years ago, but have returned one day each year to make those sweet holiday treats.  The Candy Kitchen opens at 10 a-m Saturday in the Depot Square of the Lake Superior Railroad Museum and samples are included with the regular Depot admission price.
