Add the cashews to a bowl and cover with the hot water. Allow to soak for 20 minutes.
Drain and rinse the soaked cashews and add them to a powerful blender together with the one cup of cold filtered water, onion powder/ flakes, garlic nutritional yeast and lemon juice. Process until extra creamy and smooth.
Taste and adjust seasonings to your taste with a pinch of sea salt and more lemon juice. Toss with 1/2 lb of your favorite pasta or zoodles and enjoy.

The sauce will thicken up in the refrigerator so you might want to stretch out any leftovers with a little warm water. Adjust seasonings again with sea salt before serving.
If you prefer you can use almond milk instead of water to make the sauce but it isn't necessary at all. Water works great!
