I do remember a really good recipe from a chef that marinated pork in bourbon whiskey overnight that worked really
I did the same recipe without the bourbon at another time and the taste wasn't as good
so I believe that alcohol does add something
I read further that alcohol gives a taste to the meal - like penne vodka (where alcohol does make a difference)
but I can't really place or be introspective enough about what alcohol adds to the dish
I might have read one author say that it enhances the flavors that the food already has???
not sure if anyone has any idea about how alcohol adds to the meal? would be nice to hear it if you know. thanx
