Once the cashews have soaked, drain well and add to a blender along with an additional 1/3 cup (80 ml) water (amount as original recipe is written // adjust if altering batch size). Then add grape seed oil, vinegar, spicy mustard, agave or maple syrup, dill, salt, pepper and garlic. Blend on high, scraping down sides as needed, until texture is creamy and thick but pourable. Add more water if it has trouble blending.
