Where Is Cornstarch in the Grocery Store? A Comprehensive Guide
The location of cornstarch in a grocery store is most often in the baking aisle, typically near other flours and thickening agents like tapioca starch. It might also be found in the international aisle depending on store layout.
Introduction to Cornstarch: More Than Just Thickener
Cornstarch, a seemingly simple ingredient, holds a surprisingly important place in both savory and sweet cooking. Derived from the endosperm of the corn kernel, it’s primarily valued for its thickening properties. But its uses extend far beyond simply making gravy! Understanding cornstarch – where to find it and how to use it properly – is crucial for any home cook aiming for consistent and delicious results. From crispy fried chicken to smooth sauces and delicate desserts, cornstarch plays a vital role.
The Baking Aisle: Your Primary Hunting Ground
The baking aisle is undoubtedly the most common location for cornstarch. Here’s why:
- Logical Grouping: Grocery stores generally organize items based on their intended use. Cornstarch is primarily used in baking and cooking, making the baking aisle a natural fit.
- Proximity to Similar Ingredients: You’ll often find cornstarch alongside other flours (wheat flour, almond flour, etc.), baking powder, baking soda, and other key baking staples.
- Easy Identification: Look for brands like Argo or store-brand cornstarch packaged in distinctive boxes or containers.
The International Aisle: An Alternative Location
In larger supermarkets or those catering to diverse culinary needs, cornstarch might also be found in the international aisle. This is particularly true if the store carries cornstarch from specific international brands.
- Ethnic Cuisine Connection: Many cuisines, especially Asian cuisines, rely heavily on cornstarch for thickening sauces and marinades.
- Variety of Brands: The international aisle might offer brands not found in the regular baking aisle.
Identifying Cornstarch: What to Look For
Knowing what to look for can significantly speed up your search. Here are some key visual cues:
- Packaging: Cornstarch is usually sold in cardboard boxes or plastic containers.
- Brand Recognition: Common brands like Argo are easily recognizable.
- Labeling: Clearly labeled as “Cornstarch” or “Corn Flour” (although “Corn Flour” can sometimes refer to finely ground cornmeal, so read carefully).
Uses Beyond Thickening: A Versatile Ingredient
Cornstarch is more than just a thickening agent. It plays various roles in cooking:
- Crisping Agent: Coating chicken or vegetables in cornstarch before frying helps create a crispy exterior.
- Ingredient in Baking: Cornstarch can contribute to a softer, more tender crumb in cakes and cookies.
- Slurry Creation: Mixing cornstarch with cold water creates a slurry, which is then added to hot liquids for thickening.
Common Mistakes When Using Cornstarch
Even a seemingly simple ingredient like cornstarch can lead to culinary missteps. Here are some common mistakes to avoid:
- Adding Cornstarch Directly to Hot Liquids: This can cause clumping. Always mix cornstarch with cold water first to create a slurry.
- Overcooking Cornstarch: Excessive heat can cause cornstarch to break down and lose its thickening power.
- Using Too Much Cornstarch: This can result in a gummy or pasty texture. Start with a small amount and add more as needed.
Frequently Asked Questions
Why is cornstarch not always in the same place in every store?
Grocery store layouts vary considerably based on the store’s size, target customer base, and overall merchandising strategy. This means the categorization and placement of products, including cornstarch, can differ significantly. Some stores prioritize alphabetical order within aisles, while others group items by usage.
What is the difference between cornstarch and corn flour?
The terms can be confusing, but they are different products. Cornstarch is made from the endosperm of the corn kernel, while corn flour (often labelled corn meal) is made from the entire kernel. Cornstarch is primarily a thickening agent, while corn flour adds texture and flavor to baked goods.
Can I substitute cornstarch with anything else?
Yes, several alternatives can be used. Common substitutes include:
- Tapioca Starch: Provides a similar thickening effect and is gluten-free.
- Potato Starch: Also a good thickening agent but may have a slightly different flavor.
- Arrowroot Powder: Another gluten-free option that works well in sauces and desserts.
- All-Purpose Flour: Can be used, but you’ll need about twice as much as cornstarch for the same thickening effect.
Does cornstarch expire?
Technically, cornstarch doesn’t “expire” in the sense that it becomes unsafe to eat. However, its thickening power might diminish over time, especially if not stored properly. Store cornstarch in a cool, dry place in an airtight container to maximize its shelf life.
Is cornstarch gluten-free?
Yes, cornstarch is naturally gluten-free. It is a great alternative for thickening sauces and gravies for those with gluten sensitivities or celiac disease.
What is the best way to store cornstarch?
The ideal storage conditions for cornstarch include:
- Cool: Avoid storing it near sources of heat.
- Dry: Moisture can cause clumping and reduce its effectiveness.
- Airtight: Use an airtight container to prevent moisture and pests from entering.
Can I use cornstarch to thicken cold liquids?
No, cornstarch needs heat to activate its thickening properties. You must first create a slurry with cold water and then add it to a hot liquid to achieve thickening.
What happens if I use too much cornstarch in a recipe?
Using too much cornstarch can result in a gummy, pasty, or overly thick texture. It’s always best to start with a small amount and gradually add more until you reach the desired consistency.
Can I make my own cornstarch?
Yes, it’s possible, but it’s a labor-intensive process. It involves extracting the starch from corn kernels. Unless you have a very specific need or desire to do so, it’s much easier and more efficient to purchase cornstarch from the store.
Why does my cornstarch sauce turn cloudy?
Sometimes sauces thickened with cornstarch can appear cloudy. This can be caused by:
- Insufficient Cooking: Make sure to cook the sauce long enough to fully activate the cornstarch.
- Overstirring: Excessive stirring can break down the starch molecules.
Is cornstarch the same as baking powder or baking soda?
No, cornstarch, baking powder, and baking soda are entirely different ingredients with distinct purposes. Baking powder and baking soda are leavening agents used to make baked goods rise, while cornstarch is primarily a thickening agent.
Can cornstarch be used to treat skin irritations?
While some people use cornstarch as a home remedy for minor skin irritations like diaper rash or chafing, it’s essential to consult with a doctor or dermatologist before using it for medical purposes. There are potentially better and safer alternatives available, and improper use could worsen the condition.
