Giffard Caramel Toffee Liqueur?! This is something I've never heard of, much less have in my larder. I understand why you do this kind of thing, and you do it continually, but your recipes would be tried more if you offered substitutes or how-to-make-ersatz-versions of uncommon ingredients. That way, if I liked the jury-rigged version, I'd be much more likely to go for the real thing - and Giffards would sell more. As it is, this recipe prompted me to make an Old Fashioned, period.
