I've tried many pepperoni types and styles over the past 8 months. Ezzo that you get pre-sliced from Penn Mac is very good but expensive at $5.00 per lb plus shipping. Tried Hormel, Wilson's, Bridgeford, Boar's Head, Hillshire Farms, etc.; OK but nothing special. One of the Sam's Clubs near me sells Sugardale Campioni Pepperoni in 5 lb packages for $11.50. I'd say the taste is very close to the Ezzo, easier for me to get (I live in the DFW area which is terrible for good ingredients) and quite a bit cheaper. If you can get your hands on some I'd highly recommend this brand.
