Cheese Sauce (Without the Cheese!)

From: ma299bb@sdcc6.ucsd.edu (Brett Garrett)

This stuff really resembles nacho cheese sauce, at
least to my vegetarian taste buds that haven't tasted
the real thing for years.  It's good with chips,
veggies, or on pizza instead of cheese.
I think the recipe originally came from one of
the McDougall books.

1/4 cup raw cashews (or cooked potato)
2 cups water
4 ounce jar pimientos
1 tsp salt (optional)
1/2 tsp onion powder
1/4 cup brewer's yeast flakes
3 Tbsp cornstarch
2 Tbsp lemon juice

Place the cashews in a blender and add just enough water to cover.
Blend at low speed until smooth.  Add the remaining ingredients
and blend again until smooth.  Pour into a heavy saucepan and
cook at medium-high heat, stirring constantly, 7-8 minutes,
until it thickens to the consistency of nacho cheese.
Serve hot.
