My sweetheart and I stumbled upon Kozlik's mustard while on a St. Lawrence Market Saturday afternoon date about a year ago. What drew us to the mustard shop were (of course) the free samples!
Kozlik's cooks up hot back bacon from the market right at their front counter and gives you to opportunity to try as many mustard types as you can handle with the bacon. For the vegetarians out there - pretzel sticks are also provided for dipping.
In terms of the mustards... There is definitely something for everyone!
My current personal favourite is the Curry mustard, while my sweetheart prefers the Bewitching Balsamic (a delicious mix of mustard and balsamic vinegar - which sounds strange, but is actually quite tasty).
There is something for everyone at Kozlik's - They have mustards that range from mild and sweet to extremely hot and spicy (like the XXX).
The mustards are also relatively inexpensive: $6 each or 4 for $20.
For the mustard lovers out there, this place is an absolute must :)
