2 parts water
2 parts vinegar
2 parts hemp oil
Shake with herbs and serve....
Now, is it just me, or are their ratios a little... groovy? If you have "two parts" of everything, then you have "equal parts" or "one part"of each. You don't say "two parts" of every ingredient.
So I think they must have been using a particular "herb" in their dressing, when they wrote this recipe.
By the way, we use hemp oil for nutritive purposes, not that there are any other purposes (that I'm aware of, anyway). I put it in our smoothies instead of flax oil sometimes, because it's so good for you (wiki). It's not one you'd use for cooking, so raw in salad dressing or other applications is appropriate.
