Surface Cooking
Using the griddle
The griddle is intended for direct food cooking
and can be used on both sides. Do not use pans
or other cookware on the griddle. Doing so could
damage the finish. With the grate in position over
the burner, set the griddle on top of the grate
positioning the notches in the griddle over the
grate fingers (refer to figures 1 and 2 for optimal
positioning).
Using the simmer plate (accessory not included)
The simmer plate is intended to diffuse lower temperature of the
burner to help cooking delicate aliment such as chocolate, milk,
bechamel, etc. It can also be use for cooking sauce during long
period. With the grate in position over the burner, set the simmer
plate on top of the grate positioning the notches under the simmer
plate around the grate fingers and then place the utensil on the
simmer plate.
