Carr Valley's award winning cheeses, from Wisconsin were well stocked at the Oak Brook Costco on 9/2/05, at prices about $5/lb below Whole Foods (in River Forest). Varieties available included Cocoa Cardona, Morbay and 4 year cheddar.
Costco also had Michigan apples.
The local selection at the Capututo's in Elmwood Park is high. In past weeks they have had Michigan peaches. No more, but they have a few types of Michigan apples including Paula Red. I forget to blog about the big bushels of Michigan plum tomatoes for canning, but they're still there, if starting to looking a bit picked over. There were local onions, cukes, zukes, green peppers, eggplants and 10 lb bags of Wisconsin russet potatoes.
On LTHForum, Cathy2 asked about various cuts of offal for a stew she is making for the LTH picnic on September 8 (on that date, Forest Glen Forest Preserve will be the best place to eat in Chicago, and unfortunately I cannot make). I expected Capututo's to meet her needs, and when I visited today, as Cathy2 said to me when I gave her the lowdown, "offaly good." Fergus Henderson would feel right at home at Caputo's, at least the Harlem branch in Elmwood Park. They had the elusive calves brains, they had liver (beef, veal and pork); kidneys both veal and pork, tripe, lotsa extremities like tails and feet. The only couple of things I did not see were tongue (I'm sure it's there, just did not look) and sweetbreads.
I mention the offal not so much to gross people out, but because I think that eating offal is part of the whole Eat Local thing, that is showing respect for the creatures we eat, eating mindfully, and not just supporting the worst in factory farms. Of course, the offal at Caputo's may not be local, but it's one of those things, like buying in bulk, that's local in spirit.
