Notes about the chart
120
When baking deep frozen products such as chips,
croquettes, cakes, pizza and baguettes, use the lowest
temperature quoted on the manufacturer's packaging.
Cook large frozen items e.g. cakes, pizzas and baguettes on
baking parchment on the rack. Baking large frozen items on
the baking tray or the universal tray can cause the metal to
distort to such an extent that the tray cannot be taken out of
the oven.
Small items of frozen food such as oven chips or potato
croquettes can be cooked on the universal tray. Place them
on baking parchment and turn several times during cooking.
When baking cakes with a moist topping only bake on one
level.
Bake on a maximum of two levels at the same time.
Use shelf levels 1 and 2 when baking on 2 levels at the same
time.
Select the lowest temperature in the chart.
Do not set a temperature higher than that recommended.
Increasing the temperature may reduce the baking duration,
but will lead to uneven browning, and unsatisfactory cooking
results.
Check if the food is cooked at the end of the shortest duration
quoted.To check if a cake is ready, insert a wooden skewer
into the centre. It is ready if the skewer comes out clean,
without dough or crumbs sticking to it.
