The Globe has a nice piece on the attempt to make Saskatoon berries into big business. They could qualify as "super-berries" (such as blueberries, pomegranates and the Amazonian açai) some of which are making a lot of money. But: super-berries may only have magic anti-oxidant qualities in their raw form--not juiced or processed, which is how you usually get them. So the wholesome, prairie entrepeneurs of the Saskatoon berry have to consider whether they are being honest in their sales pitch.
A lot of risks in the business. Still, the Saskatoon is one of my favourite berries, and something I miss about the West.
