48Disinfecting▯ Before you begin preserving the food, the glassesshould be disinfected in the oven to prevent thefood from spoiling. This is the only way to ensurethat preserves keep for a relatively long time andcan be stored outside of the refrigerator.▯ Disinfect the empty jars at 100 °C for at least20 minutes in the "Hot air" (fan-oven) setting. Thelids and rubber preserving seals for the jars can bedisinfected at the same time in boiling water toavoid them drying out in the dry heat of the oven.Drying▯ Drying is a method of preserving food in which upto 50% of the liquid contained in the food isremoved by exposing it to dry heat. This also makesthe flavour more intense.▯ The thicker the food, the longer the drying processlasts. The quickest way to dry food – which is alsothe method that saves the most energy – is to cut itinto slices.▯ Place the prepared food onto a wire rack or bakingtray covered with greaseproof paper. Turn the foodfrom time to time during the drying process.▯ The duration depends on the thickness of the foodand on the natural level of moisture in the food, i.e.tomatoes take longer to dry out than mushrooms.▯ If you want to dry food in the oven on two levels atthe same time, use levels 1 and 3 (or 2 and 4).Dish Accessories Level Temperaturein °CHeatingfunctionCookingtimein min.CommentsDisinfecting Wire rack 2 (3) 100 H / I 20 - 25 Preserving jars, baby bottlesDish Accessories Level Temperaturein °CHeatingfunctionCookingtime inhoursCommentsSliced mushrooms Wire rack +greaseproofpaper2 (3) 50 - 60 H / I 3 - 4Apple rings Wire rack +greaseproofpaper2 (3) 50 - 70 H / I 5 - 8Quartered tomatoes Wire rack +greaseproofpaper2 (3) 60 - 70 H / I 7 - 8 Core the tomatoes to avoid an extendeddrying time.Herbs Wire rack +greaseproofpaper2 (3) 50 - 60 H / I 1½ - 2 e.g. chives, parsley and sage
