Classic Yellow Mustard

Yellow mustard is a summer staple, with gatherings full of potato salad, egg salad, hot dogs, hamburgers, honey mustard dressing, and more.  Sure, I like the traditional brand, but I get this feeling like I totally rule the world when I can make something myself.  It de-mystifies things.  I originally tracked down this recipe because of avoiding supporting the big food brands for GMO reasons, and it’s surprisingly difficult for me to give up mustard.  I just can’t do it.  I NEED mustard.  It makes sandwiches so much better!

Unlike the Homemade Spicy Brown Mustard, this doesn’t require sitting overnight for the vinegar to do its thing, the process is done on the stovetop.  This recipe does have flour in it so it isn’t gluten free, while the storebought kind says it is gluten free, just something to keep in mind.  It’s adapted from Top Secret Recipes which has a great collection of copycat recipes, check them out if there are any you’re looking for!

When picking out mustard powder, don’t get it in the glass jars at the grocery store – it’s far less expensive when purchased at ethnic specialty markets, plus that supports local businesses.  If you can’t find mustard powder, get whole mustard seeds and run them through a spice grinder until it’s fine dust.
