I came across Kozlik's at the St. Lawrence market.
I enjoy good mustard, and Kozlik's certainly knows the game.
I bought several jars of various mustards from them... And now sadly I've ran out of all of them.
The XXX hot has a nice heat.
The honey lime mustard is soooo good and unexpected.
Extremely reasonably priced. Their jars are $6ish, and are huge. You'd pay twice that at most stores for a gourmet mustard that's probably not quite up to this caliber.
I know they sell them online, but I constantly think I need to go back to Toronto just for this mustard!
