Why Cornflour Quality Actually Matters in Your Kitchen
Cornflour is one of those pantry staples that seems interchangeable until you use a poor-quality version and wonder why your sauce turned gluey, your fried chicken coating fell off, or your custard set with an odd texture. Fine, well-milled cornflour disperses cleanly, thickens smoothly, and adds the right amount of crispness to a fried coating. The best brands mill consistently to a powder fine enough that even a slight excess doesn’t create a pasty mouthfeel.
Top 5 Cornflours
1. Bob’s Red Mill Cornstarch. Bob’s Red Mill sources non-GMO corn and mills to a consistent fine powder that disperses easily in both cold slurry and batter applications. It’s widely available, reliably consistent bag to bag, and the 22-ounce resealable bag format keeps it fresh through extended use. The top pick for most home cooks.
2. Argo Cornstarch. Argo has been a standard in American baking for over a century, and its performance holds up. The texture is slightly finer than Bob’s Red Mill, which some bakers prefer for very delicate applications like angel food cake or Chinese-style velveting. Available in large box formats that offer good value for high-volume use.
3. Clabber Girl Cornstarch. A Midwest staple that deserves wider recognition. Clabber Girl mills clean white cornstarch with a very neutral flavor profile that doesn’t compete with delicate sauce ingredients. It performs especially well in clear fruit pie fillings where a slightly gluey off-flavor from cheaper starch would be noticeable.
4. Anthony’s Organic Cornstarch. For cooks who prioritize organic certification, Anthony’s offers a verified non-GMO, USDA certified organic cornstarch that performs comparably to the leading conventional brands. It’s available in bulk bags, making it economical for households that go through large quantities in regular baking or frying.
5. Rumford Cornstarch. Rumford is the value-tier choice that still performs well enough for everyday thickening and coating tasks. It’s widely available in grocery stores at a lower price per ounce than the premium brands, and for a weekly stir-fry sauce or quick gravy, the performance difference is minimal.
What to Look for in Cornflour
Fineness of grind. The finer the grind, the smoother the thickening and the more even the coating. Premium brands mill more consistently than budget options. You can assess grind quality by rubbing a pinch between your fingers. it should feel silky, not gritty.
Non-GMO or organic certification. The majority of corn grown in North America is genetically modified. If this matters to your household, verify certification on the label rather than relying on vague “natural” marketing language. Bob’s Red Mill and Anthony’s are the most accessible non-GMO options.
Packaging integrity. Cornflour absorbs moisture and odors readily once opened. Resealable bags or tight-fitting box lids extend shelf life significantly. Avoid bulk bins in stores with high turnover of this specific product. clumped cornstarch that’s absorbed humidity will perform unevenly.
Value per ounce. Cornstarch is inexpensive even at the premium tier. The price difference between the best and cheapest options is minor enough that buying the better-performing brand almost always makes sense.
Final Thoughts
Bob’s Red Mill is the easiest recommendation for most cooks. non-GMO, consistent, and available almost everywhere. Argo’s extra-fine grind earns it a spot in kitchens where delicate sauces and baked goods are frequent. For budget-conscious everyday cooking, Rumford covers the basics without compromise.
Frequently asked questions
What is the difference between cornflour and cornstarch?+
In the United States, cornstarch and cornflour refer to the same product. a fine white powder made from the starchy endosperm of the corn kernel. In the United Kingdom and Australia, cornflour means the same thing as U.S. cornstarch. American-style cornmeal is sometimes called cornflour in the UK when ground very fine, so context and region matter when reading recipes.
Can I substitute cornflour for flour in baking?+
Cornflour cannot replace all-purpose flour in a 1:1 ratio for structure-dependent baking like bread or cakes. It's used in small proportions. typically replacing 25-30% of all-purpose flour. to lighten the crumb and improve tenderness in cookies and shortbreads. For gluten-free baking, it's blended with other starches and flours rather than used alone.
Why does my sauce go lumpy when I use cornflour?+
Lumps form when cornflour contacts hot liquid before it's been dispersed in cold water first. Always make a slurry by mixing cornflour with an equal amount of cold water before adding it to a hot sauce or soup. Add the slurry slowly while stirring continuously. The sauce will thicken within 1-2 minutes of the slurry making contact with the simmering liquid.
