In the classic vodka version, the ethanol in the alcohol is used as an emulsifier in the sauce but doesn't really add any flavor. Since more flavor is more better, I decided to try swapping out my favorite adult beverage, and the result was a smoky take on the Italian American classic.
Despite the chatter, this claim is not actually accurate. The proof, in this case, is literally in the fine print; the Member's Mark vodka from Sam's Club has a label on the bottle stating that it was distilled in Louisville, Kentucky by I.W.A Distilling. This differs from the company producing the Kirkland brand of vodka at Costco, the LeVecke Corporation, based in Mira Loma, California.
