Granite kitchen countertops replacing tile/mortar countertops - what to remove?

Yep, you're right. But, the essence of the thread may be of interest to some current members. Both granite and marble fare better when substrated with plywood. If the cabinet height is 34 1/2" (what is needed for undercounter appliances), a total thickness above that should be 1 1/2". An add on buildup for a bullnose, or some other profile gets epoxied on and ground and polished. The back edge of the buildup hides the front edge of the plywood. This is a very common practice.
The plywood can be screwed to the cabinets and the granite is set in adhesive caulk, like Polyseamseal.
