Some foods need to be kept in the fridge to help stop bacteria from growing on them, such as food with a ‘use by’ date, cooked food and ready-to-eat food such as desserts. To help stop bacteria from growing, remember: When you’re preparing food, keep it out of the fridge for the shortest time possible….
Don’t panic. Transfer food in another saucepan without scraping and add necessary fluid. In this way your remaining food will not smell. Regarding cleaning of pan, add hot water and 1 tablet of the dish washer and leave for a few hours and then clean.
