How to use the hob burners

Hob burners

Each hob burner is controlled by a separate gas tap operated by a control knob (fig. 5) which has 3 positions marked on the control panel, these are:

– Symbol ● : tap closed (burner off)

– Symbol : High (maximum)

– Symbol : Low (minimum)

Push in and turn the knob anti-clockwise to the selected position.

Low High

Fig. 5

To turn the burner off, fully rotate the knob clockwise to the off position: ●.

The maximum setting of the control tap is for boiling, the minimum setting is for slow cooking and simmering.

All working positions must be choosen between the maximum and minimum setting, never between the maximum setting and the “OFF” position.

Electric ignition

The sparks generated by the electrodes close to the burners will ignite the choosen burner. Whenever the lighting of the burners is difficult due to peculiar conditions of the gas features or supply, it is advised to repeat the ignition with the knob on

“minimum” position.

Lighting of the hob burners

To ignite the burner, the following instructions are to be followed:

1) Lightly press and turn the knob anti-clockwise, and position the knob indicator to the symbol printed on the control panel (fig. 5).

2) Press the knob to operate the electric ignition; or, in the case of a mains failure light the burner with a match or lighted taper.

3) Adjust the burner according to the setting required.

Saucepans with handles which are excessively heavy, in relationship to the weight of the pan, are safer as they are less likely to tip.

Pans which are positioned centrally on burners are more stable than those which are offset.

It is far safer to position the pan handles in such a way that they cannot be accidentally knocked.

When deep fat frying fill the pan only one third full of oil.

DO NOT cover the pan with a lid and DO NOT leave the pan unattended.

In the unfortunate event of a fire, leave the pan where it is and turn off all controls.

Place a damp cloth or correct fitting lid over the pan to smother the flames.

DO NOT use water on the fire.

Leave the pan to cool for at least 30 minutes.

Correct use of double-ring burner

The flat-bottomed pans are to be placed directly onto the pan-support.

To use the WOK you need to place the proper stand in order to avoid any faulty operation of the double-ring burner (Fig. 6a - 6b).

How to use the Multifunction oven

OPERATING PRINCIPLES

Heating and cooking in the MULTI-FUNCTION oven are obtained in the following ways: a. by normal convection

The heat is produced by the upper and lower heating elements.

b. by forced convection

A fan sucks in the air contained in the oven muffle, which sends it through the circular heating element and then sends it back through the muffle. Before the hot air is sucked back again by the fan to repeat the described cycle, it envelops the food in the oven, provoking a complete and rapid cooking.

It is possible to cook several dishes simultaneously.

c. by semi-forced convection

The heat produced by the upper and lower heating elements is distributed throughout the oven by the fan.

d. by radiation

The heat is radiated by the infra red grill element.

e. by radiation and ventilation

The irradiated heat from the infra red grill element is distributed throughout the oven by the fan.

Fig. 7

FUNCTION SELECTOR KNOB

(Fig. 7)

Rotate the knob clockwise to set the oven for one of the following functions.

Fig. 8

THERMOSTAT KNOB

(Fig. 8)

This only sets the cooking temperature and does not switch the oven on.

Rotate clockwise until the required temperature is reached (from 50 to

225°C).

10

OVEN LIGHT

By setting the knob to this position, only the oven light comes on (15 W).

It remains on in all the cooking modes.

TRADITIONAL CONVECTION COOKING

The upper and lower heating elements come on. The heat is dispersed by natural convection and the temperature must be set to between 50° and 225°C via the thermostat knob.

The oven must be preheated before cooking.

Recommended for:

Food that requires the same degree of cooking both inside and out, for example roasts, spare pork ribs, meringues etc.

GRILLING

The infrared grill element comes on. The heat is dispersed by radiation.

Set the thermostat knob to between 50° and 200°C.

Always grill with the oven door closed.

For cooking hints, see the chapter “USE OF THE GRILL”.

Recommended for:

Intense grilling, browning, cooking au gratin and toasting etc.

Do not grill for longer than 30 minutes at any one time on full heat (200°C).

Caution: the oven door becomes very hot during operation.

Keep children well out of reach.

DEFROSTING FROZEN FOODS

Only the oven fan comes on. Use with the thermostat knob set to “0” - other positions have no effect. The food is thawed by ventilation without heating.

Recommended for:

Quick thawing of frozen foods; one kg requires approximately 1 hour.

Thawing times vary according to the quantity and type of food to be thawed.

11

HOT AIR COOKING

The circular element and fan come on. The heat is dispersed by forced convection and the temperature can be regulated to between 50° and 225°C via the thermostat knob. The oven does not require preheating.

Recommended for:

Food which has to be well-cooked outside and soft or rosy inside, for example lasagne, lamb, roast beef, whole fish etc.

VENTILATED GRILL COOKING

The infrared grill element and the fan come on. The heat is dispersed mainly by radiation and the fan then distributes it all over the oven.

Use with the door closed. The temperature can be regulated via the thermostat knob to between 50° and 175° max.

The oven must be preheated for approximately 5 minutes. For cooking hints, see the chapter “GRILLING AND COOKING AU GRATIN.

Recommended for:

Grilling where quick browning on the outside is required to keep the juices in.

For example: veal steaks, chops, hamburgers etc.




MAINTAINING TEMPERATURE AFTER COOKING OR

SLOWLY HEATING FOODS

The upper heating element, the circular element and the fan come on.

The heat is dispersed by forced convection with greater intensity in the upper part.

The temperature can be set to between 50° and 140°C via the thermostat knob.

Recommended for:

Keeping food warm after any type of cooking. Slow heating of cooked food.

CONVECTION COOKING WITH VENTILATION

The upper and lower heating elements come on and the fan.

The heat coming from above and below is dispersed by convection with ventilation.

The temperature can be set to between 50° and 225°C via the thermostat knob.

Recommended for:

Voluminous dishes and large quantities which require the same degree of cooking both inside and out, for example rolled roasts, turkey, roast legs, cakes etc.

12

COOKING ADVICE

STERILIZATION

Sterilization of foods to be conserved, in full and hermetically sealed jars, is done in the following 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 and the 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.

REGENERATION

Set the switch to position and the thermostat knob to position 150° C.

Bread becomes fragrant again if wet with a few drops of water and put into the oven for about 10 minutes at the highest temperature.

SIMULTANEOUS COOKING OF DIFFERENT FOODS

The MULTI-FUNCTION oven set on position consents a simultaneous heterogeneous cooking of different foods. Different foods such as fish, cake and meat can be cooked together without mixing the smells and flavors together. This is possible since the fats and vapors are oxidized while passing through the electrical element and therefore are not deposited onto the foods.

The only precaution to follow are:

– The cooking temperatures of the different foods must be as close to as possible, with a maximum difference of 20° - 25 °C.

– The introduction of the different dishes in the oven must be done at different times in relation to the cooking times of each one.

The time and energy saved with this type of cooking is obvious.

13

GRILLING AND “AU GRATIN”

Grilling may be done without the roasting jack on position of the switch, because the hot air completely envelops the food that is to be cooked.

Set the thermostat to position 175 °C and after having preheated the oven, simply place the food on the rack.

Close the door and let the oven operate with the thermostat on position 175 °C, until grilling is done.

Adding a few dabs of butter before the end of the cooking time gives the golden

“au gratin” effect.




ROASTING

To obtain classical roasting, it is necessary to remember:

– that it is advisable to maintain a temperature between 180° and 200 °C.

– that the cooking time depends on the quantity and the type of foods.

USE OF THE GRILL

Preheat the oven for about 5 minutes.

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.

Grilling with the oven door closed.




14

Rotisserie

(Fig. 10)

This is used for spit roasting under the grill and comprises:

– an electric motor fitted to the rear of the oven
