4 Preparation

Tips for saving energy

The following tips will help you to use your appliance in an ecological way and to save energy:

  • Use dark coloured and enamel coated trays, since the heat transmission will be better.
  • While cooking your meals, perform a preheating operation if it is advised in the user manual or cooking instructions.
  • During cooking, do not open the oven door frequently.
  • Try to cook more than one type of meal within the oven at the same time (You can cook two different meals at the same time by locating cooking bowls on the same shelf). It will be suitable to cook more than one meal after each other. The oven will already be hot.

• Defrost frozen meals before cooking them.

- You can save energy by switching off your oven a few minutes before the end of the cooking time (The oven door should not be opened).

- Use pots/pans with lids for cooking. Without a lid, the energy consumption may be up to four times higher.

- Choose the burner/plate which is suitable to the saucepan base. Always choose the correct size of saucepans for your meals. For larger burners/plates more energy is needed.

• Take care to use flat base saucepans while cooking on electrical cookers.

Pots with an even and thick bottom provide better thermal conduction. You can save up to 1/3 of electricity.

  • Pots and pans should match the size of plates. The bottom of the pot or pan should not be smaller than the plate.
  • Keep plates and pan bottoms clean. Dirt will reduce the heat transmission between plate and pan bottoms.
  • In case of longer cooking times, switch off the plate 5 to 10 minutes before the end of the cooking time. When you use the residual heat, you can save up to 20 % of electricity.

5 How to use the hob

General information on cooking

BLOMBERG HKS 81420 E - General information on cooking - 1

DANGER

Risk of fire by overheated oil!

When you heat oil, do not leave it unattended.

Never try to extinguish the fire with water! When oil has caught fire, immediately cover the pot or pan with a lid. Switch off the hob if safe to do so and phone the fire service.

  • Ensure handles of pans cannot accidentally be caught or knocked and do not get hot by adjacent heating zones. Avoid pans that are unstable and easily tipped. Pans that are too heavy to move easily when filled can also be a hazard. Only use flat bottomed pots or pans.
  • Use pans which have sufficient capacity for the amount of food being cooked so they don't boil over and cause unnecessary cleaning.
    Do not place lids on the burners. Always position pans centrally over the burners. When transferring pans from one burner to another always lift the pans do not slide them.

Tips for glass ceramic hobs

  • The glass ceramic surface is heat-resistant and insensitive to large temperature deviations.
  • Do not use the glass ceramic hob for keeping objects or as cutting surface.

  • Use pot and pans with ground bottoms. Sharp edges cause scratches on the surface.

  • Do not use aluminium pots and pans. Aluminium damages the glass ceramic surface.

DANGER

Broken glass!

Do not let any objects fall onto the hob. Even small objects (e.g. salt shaker) may damage the hob. Do not use glass ceramic hobs with cracks. Water may enter into the cracks and cause a short circuit.

If the surface is damaged in any way (e. g. visible cracks), switch off the device immediately to reduce the risk of an electric shock.

The glass ceramic hob is equipped with an operating lamp and a residual heat indicator.

The residual heat indicator indicates the position of the switched on plate and remains illuminated after switching off. (When the temperature of the plate falls below touchable temperature the indicator light will go off). Weak flicker illumination is not a problem at residual heat indicator light.

BLOMBERG HKS 81420 E - Broken glass! - 1

NOTICE

Quick heating glass-ceramic hobs emit a bright light when they are switched on. Do not stare to bright light.

Switching the plate on

The hob control knobs are used for operating the plates. To obtain the desired cooking power, turn the hob control knobs to the corresponding level.

How to operate on the multiple zone hotplates

Hobs with multiple region are used for different diameter of pans. It is a standard; the inner zone will be activated when the hob is switched on.

  1. By changing the knob position in clockwise direction, the diameter of active zone can be adjusted.
  2. While the diameter of active zone changes, there will be a "click" noise.

General information on baking, roasting and grilling

BLOMBERG HKS 81420 E - General information on baking, roasting and grilling - 1

DANGER

Risk of scalding by hot steam!

Take care when opening the oven door as steam may escape.

Tips for baking

  • Use non-stick coated appropriate metal plates or aluminum containers or heat-resistant silicone moulds.
    • Make best use of the space on the rack.
  • It is recommended to place the baking mould in the middle of the rack.
  • Select the correct shelf position before turning the oven or grill on - don't move oven shelves when hot.
  • Keep the oven door closed..

Tips for roasting

  • Seasoning with lemon juice and black pepper will improve the cooking performance when cooking a whole chicken, turkey or a large piece of meat.
  • Meat with bones takes about 15 to 30 minutes longer before it is cooked than a roast of the same size without bones.
  • You should calculate about 4 to 5 minutes cooking time per centimeter height of the meat.
  • Let meat rest in the oven for about 10 minutes after the cooking time. The juice is better distributed all

over the roast and does not run out when the meat is cut.

- Fish in a fire-resistant dish should be placed on the rack at the medium or lower level.

Tips for grilling

Grilling is ideal for cooking meat, fish and poultry and will achieve a nice brown sur-face without it drying out to much. Flat pieces, meat skewers and sausages are particularly suited for grilling as are vegetables with a high water content such as tomatoes and onions.

  • Distribute the pieces to be grilled on the wire shelf.
  • If the grilling is on the wire shelf, locate a dripping pan under it in order to collect the fat.
  • Add some water in dripping pan for easy cleaning.
