I can provide you with common recommendations for what people typically keep in the back of their fridge:
Leftovers: Storing leftovers in the back of the fridge is a good practice, as it keeps them away from the door where temperatures may fluctuate more frequently.
Dairy Products: Items like milk, yogurt, cheese, and butter are commonly kept towards the back of the fridge where it's colder and more consistent.
Raw Meat and Fish: For safety reasons, it's advisable to keep raw meat and fish in the back of the fridge to prevent any juices from accidentally dripping onto other items.
Eggs: The egg compartment is usually located at the back of the fridge, where the temperature is cooler and helps to maintain their freshness.
Fresh Produce: Some fruits and vegetables are best stored in the crisper drawers at the back, where humidity levels can be adjusted.
Condiments: Items like sauces, dressings, and other condiments can be kept in the refrigerator door or towards the back.
Remember that proper organization and storage in the fridge can help maintain the quality and freshness of your food. Be mindful of food safety practices and follow any specific storage instructions for different items.
