DIY Fermented Mustard Recipe
- 150 g yellow mustard seeds
- 10 g salt
- 25 g fresh turmeric (or ½ tsp. turmeric powder)
- 1 clove minced garlic
- 310 - 375 ml water
- 1 teaspoon brine from a previous lacto-fermentation (or 1 pouch of commercial starter culture)
- In the 500ml jar, add the mustard seeds, salt, turmeric, garlic, and brine. Cover with water to fill the jar.
- Close the jar, install the airlock and let it ferment at room temperature for 5 to 10 days. Note: for a tangier mustard, let it ferment longer.
- Open the jar, filter the liquid, and set it aside.
Keep this delicious lacto-fermented mustard in the fridge.
Mustard can be forgotten in the fridge for several months; it will soften and lose its bitterness over time.
Spread generously on your hot dog, or with anything that looks nice with yellow!
Old-Fashioned Mustard Variation
To make old-fashioned mustard, replace half of the yellow mustard with brown or black mustard seeds.
After fermentation, only a few blasts in the blender are required to reach the desired consistency.
That’s it! A delicious traditional homemade mustard.
