This was pretty tasty – From The Vegan Table:
1-1/4 C raw cashews
1/2 C nutritional yeast
2 tsp onion powder
1 to 2 tsp salt, to taste
1 tsp garlic powder
1/8 tsp white pepper
3-1/2 C nondairy milk
3 Tbs cornstarch
1/2 C canola oil
1/4 C light (yellow or white) miso
2 Tbs lemon juice
12-16oz macaroni, cooked
Place cashews in a large-sized bowl of the food processor and finely grind–just don’t let the cashews turn to a paste. Add nutritional yeast, onion powder, salt, garlic powder, and white pepper. Pulse three more times to blend in spices.
In a heavy saucepan, combine milk, cornstarch and oil(s). Bring to a simmer over high heat. Decrease heat to low-medium, cover and simmer, stirring occasionally for 10 minutes, or until cornstarch dissolves.
With the food processor running, gradually add milk/oil mixture to cashew/nutritional yeast mixture. Blend for 2 minutes or until smooth and creamy. Next blend in miso and lemon juice.
Combine cashew cheese with macaroni noodles and serve. You may also bake it: Preheat oven to 325 and place macaroni mixture in a 8 or 9″ square baking dish (I recommend a 9″x13″ one). Cover and bake 20 minutes. Uncover and sprinkle with 1/2 C herbed bread crumbs. Continue baking, uncovered, for 15-25 minutes until topping is golden brown.
