Frequently Asked Questions
What's the difference between expiration and best quality dates for Cornstarch?
Cornstarch, like many dry ingredients, does not have a strict expiration date but rather a 'best by' date. This date indicates the period of time during which the product is expected to retain its optimal quality in terms of taste and performance. While cornstarch may still be safe to use after the 'best by' date, it might not perform as effectively in thickening sauces or gravies.
How can I tell if Cornstarch has gone bad?
To check if cornstarch has gone bad, look for any discoloration, mold growth, or unusual spots on the surface. Sniff the cornstarch for any musty or off odors. Lastly, feel the texture of the cornstarch - if it feels clumpy, hardened, or has changed in consistency, it is best to discard it.
What are the food safety risks with Cornstarch?
Cornstarch is a low-risk ingredient when it comes to foodborne illness. However, it is important to store it in a cool, dry place away from moisture and heat to prevent clumping or spoilage. Always check for signs of pests or mold before using cornstarch in recipes.
What are some pro tips for storing Cornstarch?
To prolong the shelf life of cornstarch, store it in an airtight container in a cool, dry place away from direct sunlight. Avoid storing cornstarch near strong-smelling foods as it can easily absorb odors. If your cornstarch has clumped together, you can break up the clumps by gently pressing them with the back of a spoon or using a sieve to sift it before use.
Any interesting facts about Cornstarch?
Cornstarch is a versatile ingredient used in various cuisines around the world. In Chinese cuisine, cornstarch is commonly used as a thickening agent for sauces and soups. It is also a key ingredient in making crispy coatings for fried foods in American cooking. Additionally, cornstarch has non-culinary uses such as in the production of biodegradable plastics.
