DIY Modified Corn & Potato Starch: Homemade Starch Modification

Ideal for thickening sauces, gravies, or soups, modified corn starch provides a smoother consistency and improved stability compared to regular cornstarch. In this recipe, we'll utilize safe and simple heat treatment methods to break down the raw starches, enhancing their ability to absorb liquid and withstand different cooking temperatures. Delve into the culinary alchemy behind this key kitchen ingredient and elevate your cooking skills.

Caution: Practice safety. Please wear gloves and eye protection whenever working with any chemical and work in a well-ventilated area.

Modified Corn Starch

Ingredients

Corn Starch: 1 cup
Distilled Water: 1/2 cup

Equipment

Heat-resistant glass container or beaker
Stirring rod or spoon
Kitchen scale
Stove or hot plate
Thermometer
Safety gloves, goggles, and lab coat

Instructions

Measure 1 cup of corn starch using a kitchen scale and place it in the heat-resistant glass container.

Add 1/2 cup of distilled water to the corn starch and stir thoroughly to form a smooth slurry.

Heat the mixture on a stove or hot plate over low to medium heat, stirring continuously to prevent lumps and sticking. Use a thermometer to monitor the temperature. Aim for a temperature around 150°F to 180°F (65°C to 82°C).

Continue stirring and heating until the slurry thickens and reaches the desired consistency. The modified corn starch should have a smooth texture and a glossy appearance.

Remove the container from the heat and let the modified corn starch cool to room temperature.

Once cooled, you can use the homemade modified corn starch in your vegan mayo recipe or other dishes as a thickener or stabilizer.
