My folks took a trip to British Columbia and came back with a can of Bird's Custard Powder and a recipe for Nanaimo bars that sound devine but require a filling made from this powder. Have "googled" Bird's Custard Powder but have not found a decent state-side source for it. Found one place in Pennsylvania that charged more for the shipping than for the product. Lots of recipes on-line for Nanaimo bars.
Anyone know where to get this powder in the States?
