Notes
• The white wine or beer enhances the cheezy flavor in this sauce. Trust me. We white cooking wine or Heineken 0.0 alcohol-free beer. Any light wine or beer works. If you prefer, you can also use unsweetened unflavored plant milk, drained potato-carrot water, vegetable broth, or water.• Depending on your potatoes, this sauce can get a bit thick, especially after being refrigerated. Just add a little more plant milk to thin it down a bit, if needed.• You can use another variety of potato, but they may not lend the stretchy-starchy texture required for this cheez sauce. Feel free to add 1-2 tablespoons of tapioca starch and a little more milk. This will help with the cheezy texture.
