6 Of The Best Substitutes For Mustard Powder

For those people who love cooking a range of savory dishes, you’ll be all too aware of the unique power of mustard powder. 

Also known as either dry mustard or ground mustard, mustard powder is a fantastic ingredient that can provide several dishes with a pungent, spicy taste that’s hard not to love. 

6 Of The Best Substitutes For Mustard Powder

Nevertheless, there’s no need to panic if you open your kitchen cupboard and find that you’ve run out of the versatile ingredient as there are plenty of great alternatives you can use instead. 

This guide will take an in-depth look at six of the most effective substitutes for mustard powder that you can use in your cooking. What’s more, we’ll also look to answer a few of the frequently asked questions related to substituting the popular ingredient. 

Wasabi Powder

The first substitute on our list is wasabi powder. This ingredient comes from the horseradish family and shares many of the same qualities as mustard powder in terms of taste, consistency, and sharpness. 

Wasabi is incredibly popular in Japanese cuisine, and has become a staple in many dishes around the world because of its unique, spicy flavor. It goes particularly well with raw fish dishes like sushi and sashimi. 

It’s worth keeping in mind that wasabi is notably hotter than mustard powder, so you should use it sparingly in any dishes you’re making. 

For example, if you’re substituting one tablespoon of mustard powder, you shouldn’t use any more than half a teaspoon of wasabi powder – unless of course you want to blow your head off! 

Turmeric Powder

The second alternative to mustard powder that we’ll take a closer look at is turmeric powder. This ingredient is popular in central and southeast Asia, and is well-known for its bright yellow color, as well as its distinct aroma and peppery flavor. 

What’s more, turmeric powder is considered a “super spice”, due to its anti-inflammatory properties, and other related health benefits such as a reduced risk of heart disease and a higher antioxidant capacity in the body. 

When cooking with turmeric powder, just be mindful that it provides a subtle bitter flavor. While this is what some people love about the ingredient, it can become a little overpowering if you use too much of it. 

This unique flavor and color of turmeric makes it the perfect ingredient for using in soups and as a dry marinade for cuts of meat and roasted vegetables. 

In terms of quantity, you can use the exact same amount of turmeric powder in a dish that you would use of mustard powder, making it nice and simple.

Horseradish Powder 

Much like its relative, wasabi, horseradish powder is an extremely effective substitute. What’s more, it’s a lot milder and more aromatic than wasabi powder, so it can be used much in the same way as mustard powder.

So, whether you’re looking to make a glaze, marinade sauce, soup, or salad dressing, horseradish powder will provide many of the same qualities as mustard powder. 

Moreover, horseradish powder isn’t difficult to find. It’s readily available in the vast majority of grocery stores, and comes in a number of different brands. 

When it comes to quantity, people use varying amounts of horseradish powder as a replacement for mustard powder. You could quite easily adopt a 1:1 ratio, but if you’re not the biggest fan of extra spice, perhaps using a little bit less of horseradish powder might be a better idea. 

Ultimately, if you’re looking for something a little hotter than mustard powder, but not quite as spicy as wasabi, horseradish powder is an excellent middle-ground option. 

Arugula

While this next option might seem like a bit of a strange suggestion, arugula can be used as an effective substitute for mustard powder in certain dishes if you’re really struggling. 

Also known as ‘rocket’, arugula is one of the most popular ingredients that people look to use in salads and sandwiches when following a healthy diet. 

What makes the leafy vegetable such a good alternative for mustard powder is the spicy flavor it provides. All you need to do is chop it down finely into a paste-like substance and then mix the paste into salads, dressings, and dips. 

Just be mindful that its use is a little more limited than all of the other substitutes on this list. For instance, we wouldn’t recommend using arugula for soups, glazes, or meat marinades, as the leaf can both burn and turn soggy very quickly. 

If you’re willing to give this mustard powder substitute a try, you should aim for one tablespoon of arugula for every one teaspoon of mustard powder. 

Mustard Seed 

Perhaps the most suitable replacement for mustard powder is mustard seed in its truest form. To use this ingredient as a direct substitute, you’ll need to grind the seed down into a powder using either a spice grinder or a coffee grinder. 

Alternatively, if you have plenty of time on your hands, you can use a more traditional method of pounding the seeds with a pestle and mortar. Once you’ve got your mustard seed in powdered form, make sure you store it correctly in an airtight container or jar. 

In terms of availability, there are several reputable brands that sell mustard seeds, so you shouldn’t have any difficulty buying them in whatever quantity you need. What’s more, mustard seeds are actually cheaper than processed mustard, mainly due to the fact that they don’t contain any added ingredients. 

When judging how much of your ground mustard seed to add to a recipe, it’s important to be aware that different color seeds provide varying levels of strength. For example, yellow seeds are the mildest, brown seeds are mid-strength, and black seeds are the spiciest. 

Therefore, if you’re using either brown or black seeds, it’s a good idea to reduce the amount you’re planning to add to a recipe. 

Prepared Mustard 

The final substitute on our list, and by certainly no means the least, is prepared mustard. While this paste-like ingredient takes a different form to mustard powder, it’s essentially the same thing, offering many of the same qualities. 

Therefore, it’s an excellent substitute and definitely won’t compromise any of the flavor that you’re hoping to achieve in your dish. 

Another benefit of prepared mustard is the fact that you can make it easily from scratch. All you need to do is mix dry mustard, vinegar, and water together in a blender, and you’re good to go. You can also use a pestle and mortar if you prefer this method. 

In terms of the amount of prepared mustard you’ll need to use, the ideal ratio is one tablespoon of prepared mustard for every teaspoon of mustard powder. This is because mustard powder is still in its original form compared to prepared mustard. 

Frequently Asked Questions

Can Mayonnaise Be Used As A Substitute For Mustard Powder? 

Surprisingly, most of the traditional mayonnaise recipes contain a considerable amount of dry mustard. Therefore, if you don’t have access to any of the alternatives listed above, you can use mayonnaise as a last resort. 

Does Mustard Powder Taste Like Mustard? 

While mustard powder is formed from ground mustard seeds, it doesn’t have any distinct flavor or taste on its own.

Only when it’s combined with water does it release the essential oil which is responsible for its sharp and spicy flavor. The best type of water for this is room temperature water. 

Why Should I Use Mustard Powder In A Recipe? 

The most popular reason for adding mustard powder to a recipe is to provide the dish with a greater depth of flavor. Compared to other types of mustard such as ‘wet’ mustard, mustard powder is 100% mustard without any additional ingredients.

This is reflected by the intensity of the flavor. 

Mustard powder is often used in recipes where the flavors are reduced during cooking. Therefore, anything dairy-heavy can benefit from having an extra kick of flavor and spice to cut through the creaminess.

Is Mustard Good For Weight Loss?

Eating mustard and mustard seeds can help to improve digestion, which in turn aids weight loss. However, eating mustard alone isn’t going to magically help you reach your weight loss goals.

You’ll need to add mustard to an already healthy and balanced diet in order to maximize its weight loss benefits. 

Does Mustard Oil Contain Fats? 

As is the case with the vast majority of foods, mustard does contain some fats. However, in this case, it’s important to note that not all fats are bad. 

Around 75% of the fats present in mustard oil are monounsaturated and polyunsaturated fats, with both providing a host of impressive health benefits.
