I suspect he means a lactofermenting crock, like a Hirsch. Else he should try Ace Hardware for plain stoneware crocks -- assuming Ace does business in Canada; I'm in the U.S. and don't know.
FYI, there ARE alternatives to an expensive Hirsch crock, including the Pickl-It system (also expensive) and Pickle Pro (which works with ordinary Mason jars). One can also look in Korean markets for kimchi jars/crocks.
That's it, but not a Hirsh. I'm really think the completely cylindrical crocks (Hirsh seem to have a bottle neck). Unfortunately, Ace Hardware doesn't do business here in Quebec.
I want to make a big batch of sauerkraut, so Mason jars won't cut it. However, there is a Korean store around the corner, so I'll give them a try.
Edit: Oh, just looked at the Pickle Pro system. Yeah, I could rig that up with home beer-making supplies.
