OK so this recipe doesn't taste exactly like sour cream. It tastes better! And once you learn how to make it you will never need to buy sour cream again.

Ingredients

1/2 cup raw cashew nuts (soaked for 1 hour*)
Juice of 2 lemons
1/2 teaspoon salt
Water (the amount of water you add is determined by the consistency you desire. More on that below!)

Method

Place all ingredients in a high speed blender. A small blender is best for this recipe. I use my Vitamix S30.
Blend until smooth.
If you blend just the cashews and lemon juice without any extra water you will get a "labne" consistency (like I've used in this salad, below).
Adding extra water will give a thinner consistency, so you can spoon or drizzle it over your dishes. It tastes divine with my Super-Simple Three Bean Chilli!

* Soaking the cashews will give you a smoother result when you blend them. But don't stress if you don't have the time to soak; make it anyway! The Cashew "Sour Creme" in the pic was made with unsoaked cashews, as I decided to make it on the spur of the moment. Just blend for a little longer, and accept that you won't have the same super-smooth, creamy texture as if you had soaked them.
