Cornflour, also known as cornstarch, is a pantry staple that plays an essential role in many kitchens worldwide. While it may be an ingredient that is often overlooked, cornflour’s versatility and numerous uses make it an indispensable part of both everyday cooking and baking. In the UK, one of the most trusted places to purchase high-quality cornflour is at Sainsbury’s.
What is Sainsbury’s Cornflour?
Cornflour is a fine, white powder made from the starchy part of corn kernels. Unlike cornmeal, which is coarse and used for making cornbread, cornflour is typically used as a thickening agent for sauces, gravies, soups, and desserts. Sainsbury’s offers cornflour in its grocery aisles, available in convenient packaging that is easy to store and use. Sainsbury’s cornflour is known for its purity, as it is made from non-GMO corn, ensuring a high-quality product for all your cooking needs.
Uses of Sainsbury’s Corn Flour in Cooking and Baking
Thickening Sauces and Soups: One of the primary uses of cornflour is as a thickening agent. Sainsbury’s cornflour is often employed in both sweet and savory dishes to create velvety sauces and rich gravies. For example, you might use cornflour to thicken a homemade gravy to accompany your Sunday roast, or to create a smooth consistency in a soup like butternut squash or chicken noodle. The key to using cornflour successfully is to mix it with a small amount of cold water to create a smooth slurry before adding it to the hot liquid. This ensures that the cornflour doesn’t clump together when it hits the heat.
Baking and Desserts: Cornflour is frequently used in baking, especially in recipes for cakes, cookies, and pastry doughs. When added to flour in a cake recipe, it helps create a light, tender crumb by reducing the protein content of the flour. Cornflour is also used in making custards, puddings, and pie fillings, as it gives these desserts their signature creamy texture. Sainsbury’s cornflour is perfect for these applications, allowing bakers to achieve a smooth and consistent texture every time. Additionally, cornflour is often found in shortbread recipes, where it contributes to the delicate, melt-in-the-mouth texture that is characteristic of the biscuit.
