surface browning, rack position three and four
from the top is recommended.
4. With a Branding Plate fitted, the unit is able to
aid the chef in its ability to produce "medium
rare" steaks in the front and "well done" steaks at
the rear - achieved with the sloped Branding
Plate rack position. (Shelf 2 and 3 from the top.).
5. Heating the Branding Plate under the burners
before cooking commences, also allows the
"sealed in flavoured goodness" to be achieved.
