Step 1

If using a high-speed blender, no need to soak the seeds. If using a standard blender you may want to soak them in hot water for about an hour. Then drain and rinse under cold water.

Step 2

To a blender add the seeds, milk, water, lemon juice, vinegar, salt, garlic, onion powder, mustard powder, and black pepper. Gradually increase to high speed, and blend until completely smooth. Stop to scrape down the sides of the blender as needed. Taste and adjust the amount of salt and acidity as desired. Keep in mind, the dressing will thicken in the refrigerator - you can always add water later to thin it.

Step 3

Add the herbs and pulse the blender a few times to incorporate. Pour the dressing into a jar or container, cover, and refrigerate for several hours or overnight. The flavors develop and improve as it chills.
