Ingredients

• 1 cup Yellow mustard seeds
• 1 cup Apple cider vinegar
• 1 cup Water
• 3 tablespoons Freshly grated horseradish
• 2 tablespoons Erythritol sweetener
• 1 teaspoon Salt
• 1 teaspoon Ground turmeric
• 0.5 teaspoon Garlic powder

Directions

Step 1

Place the yellow mustard seeds in a medium-sized bowl. Pour the apple cider vinegar and water over the seeds. Ensure the seeds are fully submerged.

Step 2

Cover the bowl with a lid or plastic wrap and let it sit at room temperature for 24-48 hours. This will allow the seeds to absorb the liquid and soften.

Step 3

After soaking, pour the mustard seed mixture into a blender or food processor. Add the freshly grated horseradish, erythritol sweetener, salt, ground turmeric, and garlic powder.

Step 4

Blend the mixture on high until it reaches your desired consistency. For a smoother mustard, blend longer. If you prefer a grainier texture, pulse the mixture instead of blending continuously.

Step 5

Taste the mustard and adjust seasoning if necessary. If it's too thick, you can thin it with a small amount of water, a tablespoon at a time.

Step 6

Transfer the mustard to a glass jar or airtight container. Refrigerate for at least 12 hours before using to let the flavors meld together.

Step 7

Store the keto horseradish mustard in the refrigerator. It will keep well for up to a month.
