Uneven cooking (pro-
nounced difference in
the product colouring):
temperature is too high; lower the temperature;
pan is too close to source
of heat;
lift the pan on the top guide;
different product size or
thickness;
in order to obtain an even cooking,
the product should be distributed
uniformly on each pan. In case of
solid food, the size, the layers and
the thickness must be as uniform as
possible;
non-horizontal racks;
level the appliance and check that
the racks are horizontal using the
adjustable feet: this operation is fun-
damental for an even cooking.
