The Best Vegan Nacho Cheese Sauce Recipe

Melt shortening in a medium skillet over medium heat. Add onions, garlic, and jalapeños and cook, stirring, until completely softened but not browned, about 4 minutes. Add cumin, paprika, garlic powder, and chipotle (with sauce). Cook, stirring, until fragrant and mixture starts to sizzle, about 1 minute. Add potatoes and cashews and cook, stirring, until cashews are lightly toasted, about 2 minutes. Add water and almond milk. Bring to a boil, reduce to a bare simmer, and cook, stirring frequently, until potatoes are fully tender, about 10 minutes. Transfer mixture to the jar of a high-powered blender (see note). Add hot sauce, jalapeño pickling liquid, and a pinch of salt. Start on low speed and slowly increase speed to high. Blend on high speed until completely smooth, about 2 minutes, adding water a few drops at a time as necessary to thin to desired consistency. Season to taste with more salt. Press mixture through a chinois (see note), using the bottom of a ladle to get it through. Cheese sauce can be stored in the refrigerator in a sealed container for up to 1 week. To reheat, microwave in 30 second increments, stirring in between, or reheat in a small pan on the stovetop, stirring constantly, and adding extra water to loosen sauce as necessary.
