Help a limey out here. In 'American Pie', when the good ol' boys are drinking whiskey and rye - is "rye" not a type of whiskey in this context? Or is it something else?You ever make a manhattan? Tradition calls for Rye, but here again my great uncle uses Bourbon instead. Personally I'm unable to appreciate the difference.
That said, when you switch out the only two components of a cocktail, it arguably ceases to be that cocktail.
edit: he keeps the Angostura though.
