Three wood species are used in three layers. The top and bottom layers are Maple with a center accent of Cherry. The middle layer is Walnut throughout. The recesses reveal the Walnut in its full glory. Hand recesses at both ends of the tray let you hold it securely.
The tray is 22-1/2" long, 6-3/4" wide and a little over an inch thick.
You can devise your own recipe to spice the oil or get a variety of spices ready-made. Dean Jacobs (Google the name) sells a seasoning variety pack with or without oil and also has replacement dishes shown here.
