Cornstarch

Cornstarch, a fine, white powder derived from the endosperm of corn kernels, is a kitchen workhorse often overlooked despite its remarkable versatility. This unassuming ingredient plays a crucial role in creating smooth sauces, velvety puddings, crisp coatings, and even chewy candies. Let's delve into the world of cornstarch and discover its culinary superpowers.

Introduction

While most commonly known for its thickening abilities, cornstarch is a multi-faceted ingredient with a surprising range of applications. It can be used to create light and crispy batters, prevent clumping in sauces, and even add shine to baked goods. Understanding cornstarch’s properties and techniques allows you to harness its full potential in the kitchen.

Culinary Uses

  • Thickening Agent: Cornstarch is the go-to thickener for sauces, gravies, soups, stews, and puddings. It creates a smooth, glossy texture without adding any significant flavor.
  • Stir-Fries: Cornstarch is used to create a light, velvety coating on meats and vegetables in stir-fries. This helps to seal in juices and flavors, resulting in tender and succulent dishes.
  • Batters & Coatings: Cornstarch is a key ingredient in batters for fried foods like chicken, fish, and tempura. It creates a crispy, golden-brown crust that holds up well to frying.
  • Baking: Cornstarch can be used in cakes, cookies, and other baked goods to create a lighter, more tender crumb. It can also be used to thicken pie fillings and prevent them from becoming watery.
  • Candy Making: Cornstarch is used to create chewy candies like gummy bears and jelly beans. It acts as a thickening agent and prevents the candy from becoming too sticky.

Tips 

  • Make a Slurry: Never add cornstarch directly to hot liquid, as it will clump. Instead, create a slurry by mixing cornstarch with cold water or other liquid until smooth.
  • Gradual Addition: Slowly whisk the cornstarch slurry into the hot liquid, stirring constantly to prevent lumps.
  • Cook Thoroughly: Cornstarch needs to be cooked for a short period to fully activate its thickening properties and eliminate any raw starch flavor.
  • Storage: Store cornstarch in an airtight container in a cool, dry place.

A Brief History

Cornstarch, a product of the Americas, was first isolated in the early 19th century. It quickly gained popularity as a versatile thickening agent and replaced flour in many recipes. Its use spread globally, and today, cornstarch is a pantry staple in kitchens around the world.

Nutritional Information

Cornstarch is primarily a source of carbohydrates. It contains very little fat, protein, or fiber. While it offers some energy, it’s not a significant source of vitamins or minerals.

Cornstarch, with its unassuming appearance, is a culinary powerhouse with the ability to transform your dishes. Its thickening and texturizing properties are essential for creating smooth sauces, crispy coatings, and tender stir-fries.
