Ingredients I Buy Only at Costco

I was a lawyer at Costco's corporate headquarters for several years, and worked closely with the food buyers.  There also was a Costco warehouse [store] across the street, where I shopped a couple of times a week, and loved to test out the merchandise.  I am a serious cook and I am often asked what I buy at Costco.

Before I tell you, context is important.  My household has only two adults and one dog, so a lot of Costco merchandise simply isn't suitable--a 25-pound bag of onions, for example.  There are other things that I buy rarely or never, such as cashews and coffee beans, but if I did buy them, I would buy them at Costco.  And, Costco has regional buyers so some merchandise varies from place to place.  This list focuses on food items that should be available at any Costco in the world, and I endeavor to keep it current
