9.... Cooking advice

Cooking advice

Convection cooking

Convection cooking - Heat is transferred to the foods by pre-heated air, forced to

circulate by in the cooking chamber. The heat quickly and uniformly reaches all parts of the
chamber, enabling simultaneous cooking of different types of food (providing they have the
same cooking temperature), placed on the shelves without mixing tastes and smells.
Convection cooking is particularly convenient for rapid de-freezing, and for sterilising
preserves and drying mushrooms and fruit.

Cooking desserts

Cooking desserts - Desserts require a very high temperature (usually from 150 to 200°C)

and a pre-heated oven (about ten minutes). The oven door must not be opened until at least
3/4 of the cooking time has elapsed. Whipped dough must be difficult to detach from a
spoon because excessive fluidity would prolong cooking time to no avail.

Cooking meat

Cooking meat - Meat to be cooked should weight at least 1 Kg to prevent it drying too

much. Very tender red  meats to be cooked rare, which must be cooked on the outside to
keep all their gravy, require short cooking time at high temperature (200-250°C). The gravy
ingredients must be placed immediately in the pan only if the cooking temperature is brief,
otherwise  they  should  be  added  during  the  last  half-hour.  You  can  check  the  degree  of
cooking  by  squashing  the  meat  with  a  spoon:  if  the  meat  does  not  yield,  it  is  correctly
cooked. For roast beef and fillet, which must remain pink inside, cooking time must be very
brief.  Meats  may  be  placed  on  a  plate  suitable  for  oven  cooking  or  directly  on  the  grill,
under  which  you  should  place  a  tray  to  collect  the  gravy.  When  cooking  has  finished,  we
advise you to wait for 15 minutes before cutting the meat so that the gravy does not come
out. Before being served, the dishes may be kept hot in the oven at minimum temperature.

General cleaning

General cleaning - Clean the oven when it is cold. Wash enamelled parts with lukewarm

water and soap, do not use abrasive products, steel wool, or acids, which could ruin them.
To  clean  the  steel  parts,  do  not  use  products  containing  chlorine  (sodium  hypochlorite,
hydrochloric  acid,  etc)  even  if  diluted.  Use  specific  off-the-shelf  products  or  a  little  hot
vinegar. Rinse thoroughly with water and dry with a soft cloth. Clean the glass door of the
oven with hot water only, and do not use rough cloths. Do not allow foods (especially acid
foods such as salt, vinegar, lemon, etc) to stagnate on the stainless steel parts, because they
could  deteriorate.  Do  not  wash  the  appliance  with  direct  jets  of  water,  because  if  water
enters,  this  could  limit  the  appliance's  safety.  Do  not  use  corrosive  substances  (e.g.
hydrochloric acid) to clean the oven' s support bench.

Cleaning the oven

Cleaning the oven - It is good practice to clean the oven interior at the end of every day

of duty. In this way it will be easier to remove cooking residues, preventing them from
burning when the oven is next used. Clean it accurately with hot water and soap or with the
appropriate off-the-shelf products.

Replacing oven lamp

Replacing oven lamp - Electrically switch off the appliance; unscrew the protective glass

cap (Fig. 4); unscrew the lamp and replace it with another lamp suitable for high
temperatures (300°C), with the following characteristics:
