Creamy Vegan Tomato Pasta Sauce

Stumbled across a promoted video on Facebook showing how to make a vegan alternative to cream in pasta sauces.

Simply liquidise 1/2 cup cashew nuts with 1/2 a cup of water and add to your basic tomato sauce a few minutes before the end of cooking.

I stirred this through pasta for the whole family and it was declared "one of the best pasta sauces ever", although this did not stand up to scrutiny (Me: "Oh really? Better than Pesto, Carbonara, or Bolognese?" Normal pre-teen grunting then resumed)
