I was reading SimeyC's answer and thinking "I want that thing too - I think it is called a WIFE" (in my Leave It To Beaver loving world)...
But seriosly - two things I think of:
(not new but fantastic if you haven't tried yet)
Microwave Bacon Cooker
and One Cup Coffee Brewer/server
If you are trying to surprise of person who is into these cooking gadgets - they probably have all the latest, coolest gadgets already anyway - and so many are so specific to different types of cooking. Might I suggest an entirely different approach to a gift for this type of person? Why not take them to a fancy restaurant where you have pre-arranged a tour of the kitchen where they can watch some meals being prepared and then afterward enjoy eating there too? I think people that like to cook, also like to eat. And getting to see the inner workings of an expensive resaurant and watching how they prepare the meals might be a very memorable gift.
