Peel the garlic cloves and discard the skin.
Add the soaked cashews (see post instructions or notes below on methods to soak cashews*) into a blender.
Also, into the blender add in the almond milk, maple syrup, ACV, garlic, and lemon zest, and blend until creamy. Then open the blender lid and add in the harissa and blend well.
If the sauce is too thin, place it in a pan and simmer it for about 5 minutes, stirring it often, until it thickens.
Then season with salt and pepper to taste.
