20Choice of PansPans used on the glass ceramicsmust:- Completely cover the cookingzone, and may be slightly largerthan the cooking zone- Have a plane bottom or at mostcurve slightly inward (max. 1mm) as the bottom on heating upwill curve outwards- Be thick-bottomed- Aluminium pans must minimumhave a 3,5 mm thick bottom- Steel pans and frying pans mustminimum have a 5 mm thick bot-tom- Have a completely smooth orfinely patterned bottomCheck that the planeness of the pansby placing it upside down on a tabletop and holding a ruler on the bot-tom of the pan. A concave as well asa convex bottom prolong the cook-ing time and increases the energyconsumption. If the diameter of thebottom is too small the energy con-sumption will increase and foodwhich boils over will burn and stickto the cooking zone.Pans with very shiny / light colouredbottoms may result in a slightlylonger cooking time than Pans witha lustreless / dark bottom.21Advise and Tips for Using the Cooking Zones! The pans must cover the fullcooking zone. It is OK if it isslightly larger. Remember smallportions also fit in a large pan.! The bottom of the pan must beplane - it is OK if it curves slight-ly inwards. If the bottom is con-vex the cooking time is pro-longed considerably. A lopsidedbottom can increase the energyconsumption by 50%.! Use tight-fitting lids on the pan.Without a lid on the pan you use3 times as much power.! Save water: Use as little as pos-sible water when boiling.Boil potatoes and vegetables with1, 2 or 3 decilitre of water.Use 1 decilitre of water on the 14cm cooking zonesUse 2 decilitre of water on the 18cm cooking zoneUse 3 decilitre of water on the 21cm cooking zone! Put a tight-fitting lid on thepan. Bring to the boil at the high-est setting and turn down to thelowest possible setting whenthere is heavy steaming at the lid.Calculate the cooking time fromwhen you turn down. Do notcheck the potatoes/vegetables tillthe cooking time has expired.! Turn down immediately whenthe liquid boils.Chose the correct setting.Start at the highest setting andturn down as much as possiblewithout the foodstuff going offthe boil.! Use the residual heat: Turn offthe cooking zone 5 minutesbefore the cooking time expires.! Use the hot cooking zone for thenext boiling.! Defrost the food in the fridgebefore cooking.! Save energy by preparing food ina pot on a cooking zone insteadof preparing the food in the oven.By using below advise youcan save energy and easecleaning.
