Chef John's Dijon Mustard

• servings: 64 servings
• active time: 15 minutes
• total time: 8 days 45 minutes

Ingredients

1 ½ cups white wine

1 cup water, or more as needed

⅔ cup white wine vinegar

1 yellow onion, chopped

2 cloves garlic, minced

1 cup whole yellow mustard seeds

¼ cup dry mustard

1 tablespoon garlic powder

1 teaspoon salt

4 1-pint canning jars with lids and rings

Directions

Gather all ingredients.

Combine white wine, water, vinegar, onion, and garlic in a saucepan; bring to a boil, reduce heat to medium low, and simmer until flavors combine, about 15 minutes.

Cool to room temperature and pour through a strainer into a large bowl; reserve liquid and discard onion and garlic.

Stir mustard seeds, dry mustard, garlic powder, and salt into strained liquid; cover the bowl with plastic wrap and let sit at room temperature until mixture thickens, 24 to 48 hours.

Purée mustard mixture to desired consistency using a stick blender.

Transfer mustard mixture to a saucepan and add enough water to reach a smooth consistency. Bring mustard to a simmer, reduce heat to medium, and cook, stirring constantly, until flavors combine, about 10 minutes.

Pack mustard into hot, sterilized jars, filling to within 1/4 inch of the top. Run a knife or thin spatula around the insides of the jars after they have been filled to remove any air bubbles.

Wipe the rims of the jars with a moist paper towel to remove any food residue. Top with the lids and screw on the rings. Refrigerate mustard until flavors blend, at least 1 week.

Serve and enjoy!
