This easy, homemade mustard relish takes only a few minutes but gives big flavor to a variety of foods.  Make a small or large batch of this condiment, it keeps a long time in the refrigerator.



Mustard Relish

  • 1/2 cup unsweetened pickle relish*
  • 2 tablespoons whole grain mustard *
  • 1 teaspoon garlic powder
  • 2 teaspoons prepared horseradish
  • 2 tablespoons chopped onion (yellow, white or red)
  • 2 teaspoons sugar (or sugar substitute)*
  • 1/4 teaspoon celery seeds
  • 1/8 teaspoon red pepper flakes
  • salt and pepper to taste


  • 5 links bratwurst
  • 1/2 cup liquid from can of sauerkraut (save sauerkraut to serve with brats)*
  • 1/4 cup apple cider vinegar
  • 1/2 cup chopped onion
  • 1/2 teaspoon garlic powder
  • 1/4 teaspoon celery seed
  • 2 tablespoons brown sugar (or brown sugar substitute)*


Mustard Relish

  1. Combine relish, onions, sugar, mustard, horseradish and spices.  Taste test for sweet and spicy.  Add what you need for your preference.  Keep in refrigerator until needed.

Grilled Brats

  1. Combine all ingredients except the brats in a large fry pan and bring to a boil.  Add the brats, do not pierce, and let them simmer in the liquid for about 5 - 6 minutes.  No need to cover the pan.
  2. If you aren't quite ready to grill them,  turn off the heat and leave the brats in the liquid for up to 30 minutes.  Any longer than that, drain the brats and store in refrigerator until grill time.
  3. Using an indoor or outdoor grill, cook the brats on medium flame, turning once, until they register 160°F on a meat thermometer.   
  4. Serve brats with mustard relish.                            


*If you don't have relish, you can use finely chopped dill pickles instead. 

*Use water or broth instead of the sauerkraut liquid if you prefer.

*Any sugar is fine if you don't have brown; you just want a bit of sweetness to compliment the apple cider vinegar.  I use Swerve brown sugar for a sugar free option.

*Don't skip the simmer step for the bratwurst.  It will help them cook evenly and keep their juices inside the brat and not seep out.
