When it comes to thickening sauces, soups, and mixtures, cornstarch is often the go-to solution. However, there are situations where cornstarch may not be the best option, or you may simply want to explore alternative thickening agents. In this article, we will delve into the world of thickening agents, discussing the pros and cons of various alternatives to cornstarch.
Understanding Thickening Agents
Thickening agents are substances that increase the viscosity of a liquid, transforming it into a thicker, more gel-like consistency. These agents work by absorbing excess liquid, swelling, and forming a network of particles that trap liquid and create a thicker texture.
Types of Thickening Agents
Thickening agents can be broadly classified into two categories: starch-based and non-starch-based.
- Starch-based thickening agents, such as cornstarch, tapioca starch, and potato starch, are derived from plant sources and work by absorbing liquid and swelling.
- Non-starch-based thickening agents, such as gelatin, agar agar, and carrageenan, are derived from animal or plant sources and work by forming a network of particles that trap liquid.

Tapioca starch is also gluten-free and can be used in gluten-free baking, while cornstarch may contain gluten due to cross-contamination during processing. Overall, tapioca starch is a good choice for dishes where a neutral flavor and clear texture are desired, while cornstarch is a good choice for dishes where a thicker and more opaque texture is desired.
Can I use flour as a thickening agent in sauces and soups?
Yes, flour can be used as a thickening agent in sauces and soups, but it’s not always the best choice. Flour can add a starchy or floury flavor to the dish if not cooked properly, and it can also make the sauce or soup cloudy or opaque. However, flour can be a good choice for thickening sauces and soups that are cooked for a long time, such as stews or braises, as the long cooking time can help to break down the starches in the flour and eliminate any raw flavor.
To use flour as a thickening agent, it’s best to mix it with a small amount of fat or oil to create a roux, which can then be gradually added to the hot liquid. This helps to prevent lumps from forming and can also add flavor to the dish. It’s also important to cook the roux for a sufficient amount of time to break down the starches and eliminate any raw flavor. A general rule of thumb is to cook the roux for at least 5-10 minutes, stirring constantly, before adding it to the hot liquid.
What is agar agar and how is it used as a thickening agent?
Agar agar is a vegan alternative to gelatin that is derived from red algae. It is a popular thickening agent in many Asian desserts and can be used to thicken a variety of dishes, from desserts to savory sauces. Agar agar is available in powder or flake form and can be dissolved in hot water to create a gel-like texture.
To use agar agar as a thickening agent, it’s best to dissolve it in a small amount of hot water and then add it to the dish. Agar agar can be used to thicken both hot and cold liquids, and it can also be used to create a firm or soft gel-like texture, depending on the ratio of agar agar to liquid. Agar agar is also a good choice for dishes that require a clear or transparent texture, as it can help to create a clear and gel-like texture without adding any cloudiness or opacity.
How do I mix thickening agents with liquid to avoid lumps?
To mix thickening agents with liquid and avoid lumps, it’s best to mix the thickening agent with a small amount of cold water or broth before adding it to the hot liquid. This helps to prevent the thickening agent from forming lumps or clumps when it comes into contact with the hot liquid. You can also mix the thickening agent with a small amount of fat or oil to create a roux, which can then be gradually added to the hot liquid.
When adding the thickening agent to the hot liquid, it’s best to stir constantly and gradually add the thickening agent in small increments, allowing each increment to dissolve completely before adding the next. This helps to prevent lumps from forming and can also help to create a smooth and even texture. It’s also important to cook the mixture for a sufficient amount of time to allow the thickening agent to fully dissolve and thicken the liquid.
Can I use thickening agents in gluten-free baking?
Yes, many thickening agents can be used in gluten-free baking, but it’s not always a straightforward substitution. Some thickening agents, such as cornstarch and tapioca starch, are naturally gluten-free and can be used as a 1:1 substitute in gluten-free baking. However, other thickening agents, such as flour, may contain gluten due to cross-contamination during processing.
When using thickening agents in gluten-free baking, it’s also important to consider the ratio of thickening agent to liquid, as gluten-free flours can behave differently than traditional flours. A general rule of thumb is to start with a small amount of thickening agent and gradually add more as needed, stirring constantly to avoid lumps.
