Love it or hate it, Kirkland’s “Real Mayonnaise” is beloved by millions across the country as a sandwich spread or snack dip. The packaging used in stores is heavily comparable to Hellmann’s iconic mayo, but supposedly Costco representatives have mentioned that food vendor E.D. Smith produces the tasty spread for its warehouse locations.
Like the large selection of meat, poultry, and seafood cuts, Costco’s selection of fine cheeses is just as spectacular. One of the more common finer cheeses in its stores is the famous Parmigiana Reggiano. To ensure quality cheese, Costco outsources many of its cheese from Italy. The Kirkland-branded Parmigiana is produced by Formaggi Zanetti. It’s even aged for a minimum of 24 months.
