My husband loves butterscotch and caramel in every form and shape, so I was happy to find a new kind of butterscotch chocolate which I bought him. Unluckily it turned out to be the worst butterscotch chocolate I ever had the misfortune to buy, so I invented this to use it up. You need not buy the worst butterscotch chocolate you can find. You may use any kind you like ;-) In fact the butterscotch chocolate thing and the amaretto are the only "bad" ingredients. If you have no amaretto liqueur or don't want to use it, you can use almond syrup or almond essence instead.
