Add the avocado, garlic, nondairy milk, vegan Worcestershire sauce, lemon juice, vinegar, brown rice syrup, pepper, paprika, and salt (and hot sauce, if using) to a blender. Blend until completely smooth. Add more nondairy milk a tablespoon at a time, if needed to blend.Add the chopped fresh herbs and blend for a short time, until the herbs are incorporated throughout (but not completely pureed).For the best flavor, refrigerate for 30 minutes before using. This avocado ranch dressing is best enjoyed the same day you make it, but will keep for up to 2 days in an airtight container in the fridge. To slow the process of oxidization, top it with a thin layer of water or oil.
