. . . cakes or biscuits are unevenly
browned.
There will always be a slight
unevenness.
If browning is very uneven, check
with Fan plus:
– whether the temperature was set too
high,
– whether the roasting filter was in
place.
– whether the correct runner height
was used.
with Conventional heating:
– the colour and composition of the
baking tins being used. Light
coloured, shiny, or thin walled tins
are less suitable.
– whether the correct runner height
was used.
. . . spots like rust appear on catalytic
surfaces.
When roasting on the rack, the
circulating air sometimes picks up
spices, which are then deposited on
the oven interior walls. Such residues
are not removed by catalytic cleaning,
they are best removed while fresh with
a mild washing up liquid solution and a
soft brush.
