The age-old debate about whether should be stored in the fridge or the cupboard has been a topic of contention for many. While some enjoy their sauce chilled, others prefer it at room temperature. However, a food safety expert has now clarified this common conundrum.

Storing food in the correct place within a fridge is crucial, especially for dairy items and meats. The specialist advised: "Place dairy products and eggs on the middle shelves, where the temperature is slightly cooler than the top but still consistent.

"Do not store them in the side of the fridge, this will cause uneven flow to the eggs, potentially causing them to go off."
