What’s the Difference Between Mustard Flour and Mustard Powder–A Quick Answer

Mustard flour and mustard powder are both made from ground mustard seeds, but they differ in their texture and intensity of flavor.

Mustard flour, made from finely ground mustard seeds has a flour-like consistency but milder taste. On the other hand, mustard powder, with a more intense flavor is made from mustard seeds ground coarsely.

Mustard flour dissolves easily and provides a smooth texture to the recipes. It also has a milder flavor compared to mustard powder.

Mustard powder has a slightly grainy texture, which makes it ideal for use in recipes that require a more robust mustard flavor. Mustard powder is often used in recipes for homemade mustard and in spice blends, rubs, and marinades.

Differences in the Use of Mustard Flour and Mustard Powder aka Ground Mustard

Mustard flour is finer and milder in flavor, while mustard powder is coarser and more intense in flavor. That’s why they vary in use. Here is a detailed overview of their culinary usage.

Use of Mustard Powder

Below are the few most common uses of mustard powder.

Spice blends

Mustard powder is often a part of spice blends, like curry powder and garam masala. It adds depth and complexity of flavor to these blends.


Mustard powder is also added to meat, poultry, and fish marinades to help tenderize the protein and add flavor.


Mustard powder is used as a base for dry rubs for grilled or roasted meats, such as pork, beef, or chicken. Most importantly, it’s the best rub for briskets.


Here are a few reasons:

  • The mustard powder has enzymes that help break down the connective tissues in the tough cut of meats. Thus, it makes the brisket more tender and easier to cut.
  • Along with other dry rub ingredients, the mustard powder helps form a flavorful crust on the surface of the brisket during cooking. 
  • The mustard powder acts as a binding agent for the dry rub. In this way, it helps in forming a sturdy bark.

Salad dressings

Mustard powder is used to add a tangy flavor to salad dressings. Likewise, it helps emulsify the oils and vinegar in salads to create a balance of texture and consistency.

Mustard powder also thickens the dressing, giving a fuller body and a more luxurious mouthfeel. 


Mustard powder is added to pickling liquids to add flavor and to help preserve the vegetables.


Mustard powder is one of the best natural leavening agents in baking. It reacts with baking soda to help baked goods rise.

In short, mustard powder is a versatile ingredient that can add flavor, texture, and complexity to various dishes.

Mustard flour uses

Mustard flour is a fine, milder version of mustard powder that is commonly used as an ingredient in dry rubs, marinades, sauces, and condiments. Here are some common uses of mustard flour:

Dry rubs

Mustard flour is often a critical ingredient in meat, poultry, and fish dry rubs. It helps to add flavor and texture and helps the rub adhere to the meat.

Sauces and marinades

Mustard flour is a key ingredient in making homemade mustard. Homemade mustard is made by mixing water, vinegar, and other seasonings to create a custom mustard flavor.


Though not typical, another use of mustard flour is as breading. Mustard flour makes a thick coating for meats or vegetables to help the bread stick with a robust flavor compared to other flours, like white flour.


Hundreds of baking recipes require mustard flour, like bread or pretzels, to add flavor and texture.

The use of mustard flour is pretty versatile. It’s used in many recipes for a specific purpose, like:

  • It can be incorporated into savory bread doughs to add a subtle mustard flavor that pairs well with other ingredients, such as cheese, herbs, or seeds.

Simply speaking, mustard flour is a versatile ingredient that particularly adds flavor and texture to savory recipes.

Mustard Powder vs. Mustard Flour–FAQs

Are mustard powder and mustard flour gluten-free?

Yes, both mustard powder and mustard flour are naturally gluten-free. They’re derived from the seeds of the mustard plant, which does not contain gluten. 

However, you must check the labels on commercial products. 


Some brands may process their mustard products in facilities that also handle gluten-containing grains, which can lead to potential cross-contamination. It would be best to look for a certified gluten-free label on your product.

Is mustard flour milder than mustard powder?

Though not completely untrue, mustard flour is milder than mustard powder but less accurate. As both are made from pure ground mustard seeds and have the same ratio of mustard seeds, they’re alike. However, there could be a few reasons why one might find mustard flour to be milder in some instances:

Different processing methods

Mustard flour is typically more finely ground than mustard powder. This difference in particle size results in a subtle difference in flavor release. 

For example, if you chew a piece of garlic clove, you’ll find it extremely pungent. It’s because most of the flavor will be freshly released while chewing it. This fresh flavor causes more robustness. And that’s what happens in your recipes. Most of the coarse ground mustard powder flavor is released during the recipe processing time.

Contrarily, if you taste a pinch of garlic powder, you can easily tolerate that on your tongue.

Seed variety

Mustard seeds come in different varieties, such as white, brown, and black, with varying levels of heat and pungency. Mustard flour is made primarily from milder seed varieties (like white mustard seeds) to maintain a color profile as well. It’s why mustard flour can taste milder than mustard powder made from a combination of seed types.

On the other hand,

The mustard powder is meant to be more colorful. Therefore, it’s made from other varieties of mustard seeds like yellow, brown, or black.

In short, the taste difference between mustard flour and mustard powder can vary depending on the seed type used. Readily, you can perceive the mustard flour as milder.

Can I use mustard powder to replace mustard flour?

Yes, you can use mustard powder as a substitute for mustard flour in the recipes. 


Use it only if the mustard flour has been advised for the sake of flavor only. Even in such a case, considering the milder flavor profile of mustard flour, you should use mustard powder in small quantities.


If you want to use mustard powder for breading or baking recipes, keeping its pungency in view, you can use it in relatively small quantities. To do so, mix it in white flour in a 1:1 ratio. 

Please remember that you can experiment with your recipe, yet the final result might have subtle differences in taste or texture.

Can I use mustard flour to substitute mustard powder?

Yes, you can use mustard flour as a substitute for mustard powder in most recipes. However, you need to keep a few guidelines in view.

As discussed in this article, mustard flour has a finer texture and milder taste than mustard powder. That’s why you’ll have to use it in a larger quantity if it doesn’t disturb the consistency of your recipe.

Compared to using mustard powder as a substitute for mustard flour, you need to be more careful when using mustard flour to replace mustard powder. 


By now, you have a comprehensive knowledge of the difference between mustard flour vs. mustard powder. We encourage you to continue experimenting with these gluten-free golden seeds in the kitchen.
