Using the electric cooker
Electric oven fan forced baking
In a fan forced electric oven the heat comes from the rear
oven element. Hot air is distributed by a fan behind the rear
wall of the compartment, providing an even temperature on
all shelf levels. This means, batches of food can be baked
using multiple shelf positions simultaneously.
Fan forced operation can be used for single food baking with
equal success.
Fan Forced baking generally requires lower temperatures than
conventional baking. Most recipe books, unless stated, are
typically for conventional oven temperatures. It is recommended
that when using the fan forced mode, reduce the oven
temperature by 10 degrees (refer to 'Oven Guide').
