The best part is when you make homemade yellow mustard, you’re in control of the ingredients, so you know what’s in it. Better still, homemade yellow mustard will keep in the refrigerator for up to a year. That’s right, a year. No need to add any additional or artificial preservatives or other ingredients you’re not sure how to pronounce. Just like when making homemade pickles, both the vinegar and salt help to preserve food. So let them do their thing in your homemade mustard as well.

If you’re going to start making things like homemade yellow mustard, you’re going to need to break a very bad habit most of us in America do every time we go grocery shopping. Simply put, we need to stop buying things in such small quantities. All that does is increase the price you pay per oz for the products you purchase.

Whether you call it ground mustard, mustard powder, dry mustard, or mustard flour, as long as you keep it dry, it will easily keep for 3 to 4 years and as long as you do things like make your own yellow mustard, you will go through it. So instead of buying those little bitty containers, buy mustard flour by the pound. You will save quite a bit of money compared to what you would spend on those tiny containers, and you’ll always have mustard flour around for other recipes that call for it as well.

When you first mix up a batch of mustard, the taste is quite hot. The secret steps to creating a bold yet milder homemade yellow mustard, by comparison, is cooking it for several minutes and then letting it age a bit. In fact, you’ll want to allow your mustard to age several days before its first use and the longer your mustard ages the milder it will become.
