Peanut sauce, a staple condiment in many cuisines, particularly in Southeast Asian and African cooking, has become a favorite among food enthusiasts worldwide. Its rich, creamy texture and nutty flavor make it a versatile accompaniment to various dishes, from satay and noodles to salads and sandwiches. However, like any food product, peanut sauce has a limited shelf life, especially after it has been opened. In this article, we will delve into the world of peanut sauce, exploring its composition, storage requirements, and most importantly, how long it remains safe and palatable after opening.
Introduction to Peanut Sauce
Peanut sauce is made from a combination of ingredients, with peanuts being the primary component. Other ingredients may include coconut milk, water, salt, garlic, ginger, and various spices.
