Cornstarch

Cornstarch, also known as maize starch or cornflour, is a fine, white, powdery substance derived from the endosperm of corn kernels. It is commonly used as a thickening agent in culinary dishes, providing a smooth texture and glossy appearance when mixed with liquids. In the kitchen, cornstarch is frequently used for thickening sauces, gravies, and soups, as well as a key ingredient in baked goods and desserts. It's popular among home cooks for its ability to thicken while remaining translucent and not affecting the flavor of the dish, making it a versatile component in various recipes.

Cornstarch FAQ
One of the most common questions about cornstarch is how to use it as a thickening agent. The best technique is to first mix it with a cold liquid (water or juice) to create a slurry before whisking it into your hot liquid. If you toss it directly into a hot liquid, it may clump and won't properly thicken your sauce or gravy. It is important not to overcook cornstarch as it could lose its thickening qualities. Another misunderstood aspect of cornstarch is its usage in baking. It can lighten the texture of baked goods when mixed with other flours, imparting a tender crumb. An interesting tip is that it can also be used as emergency anti-stick solution for kneading dough, if you've run out of flour. Frequently, people make the mistake of substituting cornstarch 1:1 for flour. While they can both thicken, cornstarch is much stronger; generally, you want to use half as much cornstarch if the recipe calls for flour. Interestingly, you can also use cornstarch outside of the kitchen for things like homemade face masks or deodorants, due to its absorbing properties.

Expiration & Storage Tips
When does cornstarch expire?
Unopened, cornstarch can last indefinitely as long as it is kept in a cool, dry place, however, it's best to use it within three years for peak freshness. Once opened, you should aim to use it within 18 months. If you use cornstarch very infrequently and have a large container, you can freeze it in a sealed, airtight container to extend its shelf life even further.
How do you tell if cornstarch is bad?
Cornstarch going bad isn't very common due to its lack of water content which inhibits bacterial growth. However, if it has been exposed to water or humidity, it may develop mold. If your cornstarch develops a foul smell or changes in color or texture, or if you see any mold, it has gone bad. Always remember to check it before use, and when in doubt, toss it out!
Tips for storing cornstarch to extend shelf life
• Keep in a cool, dry place. The pantry is a perfect place for cornstarch. • Keep it in its original box, but if you've opened it, make sure the top is sealed. Consider putting it in a clear, airtight container for easy identification and added protection from moisture. • Avoid storing it near strong-smelling foods or spices. Cornstarch can absorb odors, which could affect the taste of your dishes. • If you don't plan to use it often, you can store the whole container in a sealed plastic bag in the freezer.
