What Can I Use to Thicken My Cold Sauce?

As previously stated, there are numerous thickening agents that may be used to stiffen cold sauce. Yet, any decision one chooses may be impacted by a number of factors, including;

  • Flavor

When it comes to sauces, flavor is everything. As a result, I’m particular about any addition I use to guarantee that the taste of my sauce is not diminished but rather enhanced.

  • Gluten-free

Gluten has no nutritional purpose in the body. Moreover, its ingestion may offer a health risk to those with celiac disease. As a result, I use gluten-free thickening agents for my cold sauce.

  • Animal-free

This is a fantastic option for vegetarians. Many consumers will base their judgment on whether or not a thickening agent contains animal products.

The texture of the sauce is just as vital as its flavor. That is why I always choose an agent with consistency and creaminess.

You don’t have to deal with it! I’ve already done the legwork for you and tested the most effective techniques. You are free to agree with my or to disagree entirely.

My top picks are as follows:

It’s an all-starch component that rapidly absorbs water and expands, releasing long molecules that help with sauce thickening.

2. Arrowroot flour

Since arrowroot is gluten-free, it is a popular thickening agent among many individuals. Since it is gluten-free, it is a top pick for me.

3. Cornstarch

This corn-based thickening additive has double the power to stiffen a sauce when compared to wheat flour. As a result, it is regarded as a fantastic option since it needs minimal amounts and performs marvels.

4. Wheat flour

Proteins and carbohydrate are widely known to be present. It does, however, have a drawback in that it includes gluten. As a result, it is not a top choice for me.

Pureed vegetables

If you are a vegetarian, this is a wonderful alternative that you should not pass up! Cauliflower, beans, winter squash, and potatoes are mashed and pureed in this manner.

Incorporate the pureed components into the thin sauce and whisk quickly until completely combined. Nevertheless, keep in mind that the usage of these components will have an effect on the taste of your sauce.


The method imparts a glossy shine to the sauce. This is a quick and easy process to follow.
