You can find out which type of heating and temperature is best for your dish, which accessories to use, and at which oven level the dish should be inserted. You will find a variety of tips about ovenware and preparation, and a small troubleshooting section in case anything should go wrong. If you are baking cakes on one level, you should use top/bottom heating EJ. This will give the best results for your cakes. It is best to use dark-coloured baking tins made of metal. Baking times are increased when light-coloured baking tins made of thin metal or glass dishes are used, and cakes do not brown so evenly. Always place the cake tin on the wire grill. If you are cooking using three tins at the same time, position these as illustrated. The values in the table apply to dishes placed in a cold oven. This saves energy. Shorten the baking times indicated by 5 to 10 minutes if you have preheated the oven. The tables show which type of heating is best for different cakes and bakes. The temperature and cooking time you select depends on the quantity and type of pastry. This is why “ranges” are given in the tables. You should try to use a lower 45 temperature setting to start with, since this allows more even browning. If necessary, use a higher temperature setting the next time. More information can be found in the “Baking tips” section which follows the tables.

Baking tips You wish to cook to your own recipe. Refer to the instructions in the tables for similar types of food. How to check that a sponge cake Approximately 10 minutes before the end of the baking time is cooked properly. given in the recipe, pierce the tallest point of the cake with a cocktail stick. The cake is done if the cocktail stick comes out clean. Next time, use less liquid or decrease the oven temperature by 10 degrees. Observe the cooking times in the recipe. The cake collapses. Do not grease the sides of the springform cake tin. As soon as the cake is done, carefully loosen the cake around the edges Using a knife. The cake has risen in the centre butis lower at the edges. Insert it at a lower level in the oven, select a lower temperature and cook the cake a little while longer. The cake is too dark at the top. Use a toothpick to make small holes in the finished cake. Then drizzle fruit juice or alcohol over the top. Next time you should decrease the temperature by around 10 degrees and reduce the baking times. The cake is too dry. 48 The bread or cake (e.g. cheesecake) looks fine, but is soggy on the inside (soft, with watery areas). Next time you should add a little less liquid and cook for a little longer at a lower temperature. Cakes with fruit topping: Precook the base first of all. Sprinkle with almonds or breadcrumbs and then place the topping over this. Please observe the recipe and the baking times. The pastries are not evenly browned. Select a slightly lower temperature, as this will bake the pastries more evenly. Bake delicate pastries on one level using & top/bottom heating. Even excess greaseproof paper can affect the air circulation. Always cut the greaseproof paper down to the size of the baking tray. You have used more than one level. The pastries are darker on the upper baking tray than on the lower baking tray. Always use (6) 3D hot air to bake on more than one level. Food on baking trays put into the oven at the same time will not necessarily be ready at the same time. Condensation forms when you bake moist cakes. Steam can form during baking. Depending on the oven, it will either escape above the oven door or through the steam outlet on the hob. The steam can condense on the appliance or on the front of adjacent cabinets and drip off as condensation. This is due to the laws of physics. Meat, poultry, fish Ovenware Advice on roasting You may use any heat-resistant dishes. Always place the dishes in the centre of the wire grill. Hot glass dishes should be placed on a dry kitchen towel after being removed from the oven. The glass could crack if placed on a cold or wet surface. The roasting result depends on the type and quality of meat. Add 2 to 3 soup spoons of liquid to lean meat, and 8 to 10 soup spoons of liquid to pot roasts, depending on the size. Meat should be turned half way through the roasting time. 49 Tips for grilling Meat 50 When the roast is ready, switch off the oven and leave the roast to stand for 10 minutes with the oven door closed. This allows the meat juices to distribute more favourably. Always grill with the oven door closed. The pieces of food you are grilling should be equally thick. They should be at least 2 to 3 cm thick. This will allow them to grill evenly and prevent them from drying out. Do not add salt to the steaks until they have been grilled. Place the food to be grilled directly on the wire rack. If you are grilling a single piece, it is best to place it in the centre of the wire rack. Also slide in the enamel backing tray at level 1. The meat juices are collected here and the oven is kept clean. Turn the food over after two thirds of the specified time has elapsed. The grill element switches on and off continually. This Is normal. The grill setting determines how frequently this will happen. The table applies to insertion into a cold oven. The time specifications are provided as guidelines only and depend on the type and quality of the meat.

"*** Preheat the grill for approximately 3 minutes. 51 Poultry The table applies to dishes placed in a cold oven. The weights indicated in the table refer to oven-ready poultry (without stuffing). If you are grilling directly on the wire rack, you should also insert the baking tray at level 1. Pierce the skin of duck or goose under the wings to enable the fat to run off. Turn whole poultry after two thirds of the grilling time. Poultry will turn out particularly crispy and brown if you baste it towards the end of the roasting time with butter, salted water or orange juice.

Select the next lowest weight from the instructions and extend the time. How can you tell when the roast is ready? Use a meat thermometer (available from specialist shops) or carry out a “spoon test”. Press down on the roast with a spoon. If it feels firm, it is ready. If the spoon can be pressed in, it needs to be cooked for a little longer. The roast is too dark and the crackling is partly burnt. Check the shelf position and temperature. The roast looks good, but the juices are burnt. Next time, use a smaller roasting dish or add more liquid. The roast looks good, but the juices are too clear and watery. Next time, use a larger roasting dish or add less liquid. Steam rises from the roast when the juice is basted. Use hot air grilling instead of top/bottom heating. This prevents the bottom of the roast from becoming too hot, thereby producing less steam. 53 Bakes, gratins, toast The table applies to dishes placed in a cold oven.

Place poultry onto the plate with the breast side down. 56 Tips for saving energy in the oven on the hob Only preheat the oven if this is specified in the recipe or in the operating instructions table. Use dark, black lacquered or enamelled baking tins. They absorb the heat particularly well. It is best to bake several cakes one after the other. The oven is still warm. This reduces the baking time for the second cake. You can also place two cake tins next to each other. For longer cooking times, you can switch the oven off 10 minutes before the end of the cooking time and use the residual heat to finish cooking. Always use a saucepan which is the correct size for your food. A larger, less full saucepan requires more energy. Always place a suitable lid on the saucepan. Switch to a lower heat setting in good time. The gas flame must always be in contact with the base of the saucepan. 5/7 Acrylamide in foodstuffs Which foods are affected? Experts are currently discussing how harmful acrylamide is in food. We have compiled this information for you, based on the results of current research. Acrylamide is mainly produced in grain and potato products heated at high temperatures, such as potato crisps, chips, toast, rolls, bread, baked goods made from shortcrust pastry (biscuits, gingerbread, cookies). Tips for keeping acrylamide to a minimum when preparing food General Baking Biscuits Oven chips Roasting in the pan 58 Keep cooking times to a minimum. Cook meals until they are golden brown, not too dark. Large, thick pieces of food contain less acrylamide. Potatoes used for roasting and deep-fat frying should be as fresh as possible. You must not use green or sprouting parts of a potato. Do not store potatoes at temperatures below 8 °C. Maximum 200 °C with top/bottom heating, maximum 180 °C with 3D hot air. Egg white and egg yolk reduce the formation of acrylamide. Maximum 190 °C with top/bottom heating, maximum 170 °C with 3D hot air. Spread out a single layer evenly on the baking tray. Bake at least 400 g per baking tray so that the chips do not dry out. Boil potatoes before roasting them. For raw potatoes, use margarine instead of oil. A surface thermometer is useful for checking the surface temperature in the pan (e.g. order no. 0900.0519 from testo). Heat the roasting pan on the highest level. Once the pan reaches 150 °C, turn the heat back down to the setting desired for the remaining cooking time. Tips for keeping acrylamide to a minimum when preparing food Deep—fat frying Fat should not be hotter than 175 °C. Check the temperature with a fat thermometer. The ratio of fat to food should be between 1:10 and 1:15, e.g. 100 g chips in 1.5 1 ail. Soak potatoes for one hour before deep frying. 59 Test dishes In accordance with DIN 44547 and EN 60350 Baking The values in the table apply to dishes placed in a cold oven.
