When it comes to cooking and baking, thickening agents are essential for achieving the right consistency in various dishes, especially desserts like puddings. One of the most commonly asked questions in the world of pudding making is whether cornstarch can thicken cold pudding. The answer might surprise you, but before we dive into that, let’s explore the world of pudding thickening agents and why cornstarch is often considered a top choice.
Understanding Pudding Thickening Agents
Thickening agents are substances that help increase the viscosity of a liquid, creating a desired consistency in sauces, soups, custards, and puddings. There are several types of thickening agents, each with its unique properties and uses. Some of the most common thickening agents include:
- Flour: A common thickening agent in gravy and sauces, flour is often used in combination with butter or oil to create a roux.
- Cornstarch: A popular choice for pudding making, cornstarch is often used in desserts like custards, puddings, and sauces.
- Tapioca starch: A starchy powder extracted from the cassava plant, tapioca starch is often used in Asian desserts and sauces.
- Egg yolks: Whole eggs or egg yolks can be used as thickening agents in custards, sauces, and ice cream bases.
The Role of Cornstarch in Pudding Making
Cornstarch is a popular thickening agent in pudding making due to its unique properties. It is:
Odorless and flavorless: Cornstarch doesn’t add any unwanted flavors or scents to your pudding, making it a great choice when working with delicate flavors.
Easy to mix: Cornstarch dissolves quickly and easily in liquid, making it a convenient thickening agent.
Provides a smooth consistency: When cooked properly, cornstarch can create a smooth, velvety texture in puddings.
Can Cornstarch Thicken Cold Pudding?
Now, the million-dollar question: can cornstarch thicken cold pudding? The short answer is no, cornstarch cannot thicken cold pudding. But why is that?
The Science Behind Cornstarch Thickening
Cornstarch thickening relies on a process called gelatinization. When cornstarch is mixed with a hot liquid, the heat breaks down the starch molecules, creating a gel-like substance that thickens the liquid. This process occurs around 180°F to 190°F (82°C to 88°C), which is why cornstarch is often cooked with milk or cream to create a smooth, thickened pudding.
The Problem with Cold Pudding
Cold pudding, by definition, is a dessert that hasn’t been heated or cooked. Since cornstarch requires heat to activate its thickening properties, it won’t thicken a cold pudding. Even if you mix cornstarch with a cold liquid, the starch molecules won’t break down, and the mixture will remain thin and runny.
Alternative Thickening Agents for Cold Pudding
So, what can you use to thicken cold pudding? Here are a few alternatives to cornstarch:
Tapioca Starch
Tapioca starch is a popular thickening agent in cold desserts like puddings and custards. It can be mixed with cold liquids and still provide a smooth, thick consistency. However, tapioca starch can add a slightly sweet flavor to your pudding, so use it sparingly.
Gelatin
Gelatin is a protein derived from animal bones and connective tissue. It’s often used in cold desserts like puddings, jellies, and custards. Gelatin dissolves in cold water and can be used to create a firm, jelly-like texture.
Agar Agar
Agar agar is a vegan alternative to gelatin, derived from red algae. It’s often used in Asian desserts and can be used to thicken cold puddings. Agar agar dissolves in hot water, but it can be cooled and used to thicken cold desserts.
Tips for Thickening Cold Pudding
When working with cold pudding, it’s essential to use the right thickening agent and mix it correctly. Here are some tips to keep in mind:
- Use the right ratio: Make sure to use the correct ratio of thickening agent to liquid to achieve the desired consistency.
- Mix thoroughly: Mix the thickening agent with the liquid until it’s fully dissolved and there are no lumps.
- Chill thoroughly: Chill the pudding mixture in the refrigerator until it’s set and firm.
Conclusion
In conclusion, cornstarch cannot thicken cold pudding due to its reliance on heat for gelatinization. However, there are alternative thickening agents like tapioca starch, gelatin, and agar agar that can be used to achieve a smooth, thick consistency in cold puddings. By understanding the science behind thickening agents and following the right mixing and chilling techniques, you can create delicious, smooth puddings that are perfect for hot summer days.

Why does my cold pudding need thickening?
Cold pudding can be a delicious and refreshing dessert, but sometimes it can turn out too runny or thin. This can be due to a variety of reasons, including using the wrong ratio of ingredients, not enough cooking time, or adding too much liquid. Thickening the pudding can help it achieve the right consistency and texture, making it more enjoyable to eat.
When a pudding is too thin, it can be difficult to hold its shape and can be prone to weeping or separation. Thickening the pudding can help it hold its shape and maintain its texture, even when it’s refrigerated or frozen. Additionally, thickening can help balance out the flavors and make the pudding more satisfying to eat.
Can cornstarch really thicken cold pudding?
Yes, cornstarch can be an effective thickener for cold pudding. Cornstarch is a common thickening agent that works by absorbing excess moisture and swelling to thicken the mixture. When mixed with a liquid and heated, the starches in the cornstarch break down and thicken the mixture. However, cornstarch can also be used to thicken cold mixtures, including cold pudding.
To use cornstarch to thicken cold pudding, you’ll need to mix it with a small amount of cold water or liquid to create a slurry. Then, slowly add the slurry to the pudding, whisking constantly to prevent lumps from forming. Start with a small amount of cornstarch and add more as needed, as it’s easier to add more thickener than it is to remove excess.
How much cornstarch do I need to thicken my cold pudding?
The amount of cornstarch needed to thicken cold pudding will depend on the type of pudding, its consistency, and the desired thickness. As a general rule, start with a small amount of cornstarch, such as 1-2 tablespoons per cup of pudding. You can always add more cornstarch if needed, but it’s harder to remove excess thickener.
It’s also important to note that the type of cornstarch you use can affect the thickening power. Some cornstarches are designed specifically for thickening cold mixtures, while others may be better suited for hot mixtures. Be sure to check the packaging or manufacturer’s instructions for guidance on using cornstarch to thicken cold pudding.
Can I use other thickeners besides cornstarch?
Yes, there are several other thickeners you can use to thicken cold pudding, depending on the desired flavor and texture. Some popular alternatives to cornstarch include gelatin, agar agar, tapioca starch, and pectin. Each of these thickeners has its own unique characteristics and may be better suited to certain types of pudding.
For example, gelatin is a good thickener for creamy puddings, while agar agar is often used in vegan and vegetarian recipes. Tapioca starch is a good thickener for fruit-based puddings, while pectin is often used in jam and jelly recipes. Experiment with different thickeners to find the one that works best for your cold pudding recipe.
