Homemade yellow mustard is a DIY riff on the classic American condiment. The store-bought stuff can’t touch this. And it’s remarkably easy to make from mustard powder, vinegar, and a couple of other pantry staples.–Renee Schettler

WHAT IS A NON-REACTIVE SAUCEPAN AND WHY DOES IT MATTER?

A “nonreactive” saucepan is one that doesn’t react with the food being cooked. By contrast, acidic foods are reactive and are typically problematic. Foods like tomatoes, wine, cranberries, lemon, vinegar, and pickling brine, can react with your cookware. Why does this matter? Because chemistry, baby. Acidic ingredients will react with certain metals—leaving you with a damaged pot and metal material in your food. Stainless steel cookware is typically considered nonreactive, as are glass and earthenware. Enamel-finished cast iron pots also non-reactive unless there are any chips or cracks in the enamel.

LC DRY MUSTARD NOTE

Just a word of caution before you start making this amazing condiment. Yellow, dry mustard is used in cuisines all over the world but you’ll find that American or British versions work best here. Other mustard powders may not work the same and the results might not be what you were hoping for.

Equipment

  • Nonreactive saucepan

Ingredients 

  • 1 cup cold water
  • 3/4 cup yellow dry mustard
  • 3/4 teaspoon coarse sea salt or kosher salt
  • 1/2 teaspoon ground tumeric
  • 1 teaspoon garlic purée or 1/8 teaspoon garlic powder
  • 1/8 teaspoon paprika
  • 1/2 cup white distilled vinegar

Directions
 

  • Place the water, dry mustard, salt, turmeric, garlic, and paprika in a small nonreactive saucepan and whisk until smooth. Cook the mixture over medium-low to low heat, stirring often, until it bubbles down to a thick paste, 30 to 45 minutes.

    TESTER TIP: You’re definitely going to want to do this in a well-ventilated kitchen. As in windows flung open and exhaust fan on high. Trust us. And that nonreactive saucepan is also essential or the mustard could take on an off color and hue.

  • Whisk the vinegar into the mustard mixture and continue to cook until it’s thickened to the desired consistency—you know, the usual prepared mustard consistency—which can take anywhere from 7 to 15 minutes.
  • Let the mustard cool to room temperature before spooning the mustard into an airtight container. Cover and refrigerate for up to 3 months. The mustard will be quite pungent the first few days or even weeks, but will mellow with time.

Recipe Testers' Reviews

I’ve always wanted to make my own homemade yellow mustard. I’ve heard it beats the pants off the stuff you buy—and it’s true! I’m not sure how else to describe the flavor of this homemade yellow mustard other than complex and mustardy, but trust me, you might not go back to the stuff in the squeeze bottle.

I whisked in the vinegar and let it bubble for 18 more minutes until the mustard was pretty thick. The resulting mustard is spreadable rather than squeezable. Delicious!

You may ask yourself, WHY make my own mustard when store-bought mustard seems so inexpensive? Simple. CHEAP mustard is cheap. GOOD mustard is not. This homemade yellow mustard recipe is tasty and fun and, if you are anything like me, you love to make EVERYTHING from scratch, because it almost ALWAYS tastes better.

You could add your own touches—horseradish, pepper, whatever your heart's desire—but it's not necessary, as this has a bit of heat and, is quite good just as it is. I made mine exactly as described and, after adding the vinegar, cooked it down for another 5 minutes and ended up with some REALLY FINE ballpark-style mustard!

  1. Completely wrong. Never cook your homemade mustard. Leave the paste to infuse for only 10 minutes. Heat decomposes the mustard oils, especially erucic acid, which gives the mustard its pungency.

    1. Thanks, Ralph. You are quite correct in stating that heating your mustard will definitely mellow its flavor. This recipe does make ballpark-style mustard that many people enjoy, however, if you want stronger mustard, you can reduce the amount of water and skip the cooking step.

  2. 5 stars
    I’m one of “those people” who can’t tolerate garlic. Mustard, being one of my favorite foods, has garlic as one of the basic ingredients so I turned to Chef Google, searching for mustard recipes I could make on my own and adapt as needed. Well, this recipe, and Leite’s whole grain mustard recipe, are my newfound faves! Easy to make? You bet! Easy to adapt to your liking? Yup! Delicious??? OH HECK YES! I’ve played with the liquid ingredients, using beer in place of water, soaking the seeds longer than intended while still having it turn out creamy and yummy, and toyed with various spices and herbs, changing the flavor profile to match what we were in the mood for. No longer will I need to buy mustard, and no longer will I need to search for another mustard recipe. Thank you, Leite’s!!

    1. Wow, Ringo’s Mom, not only can you have mustard, but you are having fun making it. It’s a win-win-win-and-win! Thanks for writing!

  3. Is there a reason why the mustard needs to be cooked down before adding the vinegar? English mustard powder might be hot, but the addition of vinegar is what dilutes the heat.

    1. I’m not an expert, Edward, but my understanding is that the initial cook is what develops the flavor. Once the vinegar is added, the flavor of the mustard is set and no more chemical reactions occur. If any readers have additional information, we’d love to hear from you.

      1. Mustard powder does not dissolve in the sauce After pouring the sauce on the sandwich, the mustard powder separates from the sauce and the sauce does not give any taste to the food.

        1. This isn’t a problem we’ve encountered before, امیرمهدی اسدی. Did you cook it down to a thick paste? What type of mustard powder were you using?

          1. Yellow mustard powder. Of course, I’m not sure about its purity, and I used a simple metal pot.

          2. I’m not sure what went wrong. The only other thing I can think of is that the water you used wasn’t cold enough? Mustard powder needs to be dissolved in cold water.

  4. Can another acid be used, like lemon juice? I have a strong intolerance to vinegars no matter what they are made from.

    1. Pam, we’ve never tried it with lemon juice in place of the vinegar, so we can’t say if it would work. If any of our readers have tried this, we’d love to hear from you. I suspect it would work but the flavor might be different.
