Custard is a delicious and versatile dessert that can be enjoyed in various forms, from classic crème brûlée to creamy fillings for cakes and pastries. However, like any dairy-based product, custard has a limited shelf life, and its safety and quality depend on proper storage and handling. In this article, we will explore the factors that affect the shelf life of custard, how to store it safely, and how long it can last in the fridge.
Factors Affecting the Shelf Life of Custard
The shelf life of custard depends on several factors, including its composition, storage conditions, and handling practices. Here are some key factors that can impact the shelf life of custard:
Composition
Custard is typically made from a mixture of milk, cream, sugar, eggs, and flavorings. The proportion of these ingredients can affect the shelf life of the custard. For example, custards with a higher egg content tend to have a shorter shelf life due to the risk of salmonella contamination.
