Hey there, foodies! I’m a thickener supplier, and today we’re diving deep into the world of thickeners used in gravies. Gravies are like the secret sauce that can take a simple meal and turn it into a mouthwatering masterpiece. But what makes a great gravy? Well, a big part of it is the thickener. Let’s take a look at some of the most common thickeners out there. Thickener

Flour
Flour is probably the most well – known thickener for gravies. It’s super accessible and easy to use. You can make a roux, which is a mixture of equal parts flour and fat (usually butter). Just melt the butter in a pan, add the flour, and cook it over medium heat for a few minutes. You’ll want to stir it constantly so it doesn’t burn. As you cook the roux, it’ll change color. A white roux is cooked for just a short time and is great for light – colored gravies. A brown roux is cooked longer, until it turns a nice, rich brown color, and it gives a deeper flavor to your gravy.
The thing with flour is that it can sometimes make the gravy a bit cloudy. But if you cook the roux long enough, you can reduce that cloudiness. Also, you need to be careful when adding it to your liquid. If you just dump it in all at once, you’ll end up with lumps. It’s best to slowly whisk it in, a little at a time.
Cornstarch
Cornstarch is another popular thickener. It’s got a really high thickening power, which means you don’t need to use as much of it as you would flour. To use cornstarch, you first make a slurry. That’s just a mixture of cornstarch and cold water. You want to make sure there are no lumps in the slurry before you add it to your gravy.
One of the great things about cornstarch is that it gives a clear, shiny finish to the gravy. It’s also flavor – neutral, so it won’t change the taste of your gravy. But cornstarch can break down if you cook it for too long or at too high a temperature. So once you add the slurry to the gravy, bring it to a boil, stir it well, and then turn down the heat right away.
Arrowroot
Arrowroot is a natural thickener that comes from the roots of a tropical plant. It’s similar to cornstarch in that it gives a clear, glossy finish to the gravy. It’s also more heat – stable than cornstarch, so you can cook it for a bit longer without it breaking down.
Arrowroot has a very mild flavor, so it won’t overpower the taste of your gravy. It’s a great option if you’re looking for a natural alternative to cornstarch or flour. Just like with cornstarch, you make a slurry with arrowroot and cold water before adding it to the gravy.
Potato Starch
Potato starch is another thickening agent. It’s made from potatoes, of course. It has a high thickening power, and it gives a smooth texture to the gravy. It’s also gluten – free, which is great for people with gluten sensitivities.
Potato starch works well in both hot and cold gravies. When using it, you can make a slurry just like with cornstarch or arrowroot. But be careful not to overcook it, as it can start to break down and lose its thickening ability.
Gelatin
Gelatin is a protein – based thickener. It’s commonly used in aspics and some types of rich, savory gravies. Gelatin gives a firm, jelly – like consistency to the gravy. You need to bloom gelatin first, which means soaking it in cold water for a few minutes until it softens. Then you can add it to your hot gravy and stir it well.
The thing with gelatin is that it sets as it cools. So if you want a gravy that will hold its shape, like in a molded dish, gelatin is a great choice. But if you want a more fluid gravy, you might want to use a different thickener.
Xanthan Gum
Xanthan gum is a modern thickener that’s often used in commercial food products. It’s a very powerful thickener, and you only need a tiny amount. It can give a very smooth, stable texture to the gravy.
Xanthan gum is great for thickening low – fat gravies because it can mimic the texture of fat. It’s also gluten – free. But it can be a bit tricky to use. You need to make sure it’s well – dispersed in the liquid, or you’ll end up with clumps.
Guar Gum
Guar gum is another natural thickener. It’s made from the seeds of the guar plant. It’s similar to xanthan gum in that it’s a powerful thickener and can give a smooth texture to the gravy.
Guar gum is often used in combination with other thickeners to get the best results. It’s also a good option for people who are looking for a natural alternative to some of the more processed thickeners.
Choosing the Right Thickener
So, how do you choose the right thickener for your gravy? Well, it depends on a few things. First, think about the flavor of your gravy. If you want a traditional, rich flavor, flour might be a good choice. If you want a clear, shiny gravy with a neutral flavor, cornstarch or arrowroot could be better.
The texture you want is also important. If you want a firm, jelly – like gravy, gelatin is the way to go. If you want a smooth, fluid gravy, potato starch or xanthan gum might work well.
Another thing to consider is any dietary restrictions. If you’re gluten – free, you’ll want to avoid flour and look for alternatives like cornstarch, arrowroot, or potato starch.

As a thickener supplier, I’ve seen firsthand how different thickeners can make a big difference in the quality of a gravy. Whether you’re a home cook or a professional chef, having the right thickener can take your gravy from good to great.
