27GRILLING AND COOKING AU GRATINAs the hot air completely covers the food to be cooked, grilling may be done withthe food on rack in the oven. The knob should be switched to position .The thermostat should be set to 200 °C and the oven pre-heated.The food should be placed on a rack in the oven for the required cooking time.Adding a few dabs of butter before the end of the cooking time gives the golden “augratin” effect.It is recommended that you do not grill for longer than 30 minutes at anyone time.COOKING ADVICESTERILIZATIONSterilization of foods to be conserved, in full and hermetically sealed jars, is done in thefollowing way:a. Set the switch to position .b. Set the thermostat knob to position 185 °C and preheat the oven.c. Fill the dripping pan with hot water.d. Set the jars onto the dripping pan making sure they do not touch each other andthe door and set the thermostat knob to position 135 °C.When sterilization has begun, that is, when the contents of the jars start to bubble,turn off the oven and let cool.Check your recycle book for full instructions.SIMULTANEOUS COOKING OF DIFFERENT FOODSThe oven set on position can cook several different foods together. Foods asdiverse as fish and cakes can be cooked together without the cross transference offlavours. This is because the fats and cooking smell that would normally bedeposited on the different foods are oxidised and are not absorbed by the foods.The cooking temperature of the foods, however must be within 20 - 25°C of eachother. The food with the longest cooking time will be put into the oven first andthe other foods are added as necessary according to their cooking times.ROASTINGTo obtain classical roasting, it is necessary to remember:■ that it is advisable to maintain a temperature between 180 °C and 200 °C.■ that the cooking time depends on the quantity and the type of foods.USE OF THE GRILLPreheat the oven for about 5 minutes with the door closed.Introduce the food to be cooked, positioning the rack as close to the grill as possible.The dripping pan should be placed under the rack to catch the cooking juices and fats.Do not grill for longer than 30 minutes at any one time.
