Balducci's pepper biscotti

i would like to find a recipe for these. When Balducci's was on 6th Ave in NYC, they sold a biscotti that was a " break your teeth " hard black pepper biscotti and had a different finish than regular biscotti. Looked almost like they had a water bath at some point in the cooking. But not a ring, biscuit or wreath shape. Any help would be appreciated. Thanks
