Picked up a bag yesterday at a local Chinese supermarket. I was not aware that they do not produce heat themselves but enhance other hot spices. The aroma they produce when toasted is awesome, but they are truly a pita to work with because only the husk is usable.
The black kernel is gritty and unpleasant when ground.
I made a mix of the Sichuan pepper and Black peppercorn plus a little sea salt and put it on Diver Scallops. Pan seared them on the Weber.
