I checked out a store next to my house today called Bayley & Sage and hit a motherload of American stuff. Besides the usual (pinto beans, corn meal) I found Bisquik, maple syrup, wasabi, Jelly Bellies, good pastrami, corn nuts and poppy seeds (which now I wish i'd gotten to put on the pretzels I'm baking tonight.)
There was more stuff than this, but hubby wanted to get out of there and wouldn't let me browse properly. Some time this week I'm gonna go and really explore.
