Smooth Dijon Mustard

Instructions:

1. Combine 1 cup (200g) Dijon mustard seeds, 1/2 cup (120ml) water, and 1/2 cup (120ml) white grape juice in a glass bowl.
2. Cover the mixture tightly with plastic wrap and let it sit at room temperature for 24 to 48 hours until the seeds have plumped and the liquid is mostly absorbed.
3. Transfer the soaked seeds into a high-speed blender or food processor.
4. Add 1/3 cup (80ml) white vinegar, 1 tsp (6g) salt, 1/2 tsp (2g) garlic powder, and 1/4 tsp (1g) turmeric.
5. Pulse the mixture several times to break up the seeds, then blend on high for 1–2 minutes until the texture is smooth and velvety.
6. Stop the blender and scrape down the sides with a spatula to ensure no dry clumps remain, then pulse once more to achieve the desired thickness.
7. If the mixture is too thick, add water one teaspoon at a time and blend until it reaches a spreadable consistency.
8. Transfer the finished mustard into sterilized glass jars, leaving a small headspace at the top.
9. Store the jars in the refrigerator to maintain peak flavor for up to 6 months.
