What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Don't skip the aging process! The initial bitterness right after blending is expected. Aging is essential to mellow the flavor and develop the characteristic heat.
- 2For a smoother consistency, use a high-powered blender. You can also pass the mustard through a fine-mesh sieve after blending to remove any remaining seed hulls.
- 3Adjust the heat level by changing the liquid temperature. Using cold water and vinegar will result in a spicier mustard, while warmer liquids will be milder.
- 4Store your homemade mustard in a sterilized glass jar to maximize its shelf life. It can last for several months in the refrigerator.
