Have you ever used cashews to make a cream sauce? You buy raw cashews, about 1 and 1/2 cups. Bring 2 cups of water to a boil then pour the boiling water over the cashews in a bowl.
Let the cashews soak in the water for about 10 minutes. After soaking, add the cashews to a high powered blender with about 1 cup of water. Blend and add another cup of water as needed.
Add salt, pepper garlic or anyy herbs as you would like, boom vegan cream sauce. I usually add it to sautéed veggies and mushrooms and serve it over pasta (chickpea or regular) or rice.
