You might also consider the tiniest splash of hot sesame oil if you're the type to have it lying around. YMMV but, on my tongue low enough amounts of burn are processed as a "HEY! PAY ATTENTION TO THE NEXT FLAVOR YOU EXPERIENCE!" notice. This might, _might_, allow you to do interesting things to the flavoring of the crust with your sharp cheeses or say, tiny amounts of dried apricot or some citrus flavor.
