Notes
The Nutrition Facts are an estimate only.
Soak the cashews in water overnight or boil them in water for 15 minutes. They should be soft and puffy so they break down into a creamy texture.
Add more water if you prefer a thinner dressing.
If you're making a dip, add the water slowly until you get the desired thickness.
Taste and adjust the salt and garlic to suite your taste. If you are watching your sodium intake, add the salt slowly and taste.
