When it comes to cooking and preparing meals, many of us turn to the convenience of store-bought sauces and condiments. However, there’s something special about making your own homemade pesto from scratch. Not only does it allow you to customize the flavors to your liking, but it’s also a great way to use up fresh ingredients and reduce waste. But, as delicious as homemade pesto is, it’s a perishable item that requires proper storage and handling to maintain its quality and safety. In this article, we’ll explore the topic of how long homemade pesto keeps in the refrigerator, including the factors that affect its shelf life, storage tips, and signs of spoilage.
Factors Affecting the Shelf Life of Homemade Pesto
The shelf life of homemade pesto is influenced by several factors, including the ingredients used, storage conditions, and handling practices. Here are some key factors to consider:
Ingredients
The freshness and quality of the ingredients used in your pesto recipe can significantly impact its shelf life. Fresh basil, for example, is a key ingredient in traditional pesto recipes and is more prone to spoilage than other ingredients. Additionally, the type of cheese used, such as Parmesan or Pecorino, can also affect the shelf life of your pesto.
Here are some common ingredients used in pesto recipes and their typical shelf life:
| Ingredient | Typical Shelf Life |
|---|---|
