You can also add a whole garlic head (this is for flavoring only; you can use the whole roasted garlic for a different recipe or spread it on some low-carb toast!).

    Changed this up a bit. It was sweet enough from the sweet basil and red bell pepper so I didn’t add any sweetener. Also, because I’m not vegan I used chicken bullion which made it salty enough. I used half the tomato paste. Added extra heavy cream. I did add the water which I will leave out next time so it will be thicker. Very good with a perfect texture.
