Vegan Cheese Sauce
We experimented with the familiar cast of characters used to develop vegan cheese-like sauces—cashews, nutritional yeast, and miso, along with various vegetables. Tasters were largely distracted by their vegetal flavors and pasty textures. The most neutral-tasting ingredient in the lot was potato, and we had a revelation when we broke a cardinal kitchen rule: We whirred boiled potatoes in the blender at high speed to release as much gummy, gluey starch as possible.
