Method:
Drain cashew nuts and using a high power blender or food processor blend everything except for 2 Tbsp. water, this are extra in case you need to make the sauce a bit runnier. Taste for seasoning and add more water if you'd like a more runny consistency. The sauce will be ready when is smooth and creamy.
If you make it, like it and find a new way of using it I'd love to know !
Meanwhile here are other ideas:
As a spread for sandwiches, as sauce for a vegetarian (or not) burger or adding capers and gherkin for a vegan tartare sauce for fish and chips.
* If you add 1 tsp of nutritional yeast flakes and a couple more spoonfuls of water it makes a nice vegan Caesar salad dressing.
