Sour Cream Substitutes

I've been having a hankering for sour cream. Especially made into a dip or on chili. I found the following recipe on godairyfree.org (here)
She says,

 "From the blog, Gluten Free by the Bay, this recipe is recommended as remarkably similar to real sour cream.  The author utilized a dollop of this "cream" to tame a firey soup!

Ingredients:

• 1 cup raw cashews (must not be roasted or salted)
• 1/4 teaspoon salt
• 1 to 2 teaspoons apple cider vinegar
• Juice of one small lemon

Directions:

Cover cashews with water and soak for a few hours, or overnight. Pour off all water, and place nuts in food processor. Add 1/4 cup cold water, salt, vinegar and lemon juice. Puree for 3-4 minutes or until completely smooth and creamy in consistency. Use in any recipe that calls for sour cream."

Here's a similar one at happyfoody.com (here)

1 1/2 cups soaked cashews (soak 8 hours and rinse)
1/2 t salt
2 T lemon juice
Approx. 3/4 cup fresh water

Blend in blender until smooth. Add more lemon juice or salt to taste.

I haven't tried it yet, but would love to hear what you think. It said if you eat it plain it tastes like, well. . . cashews. . . but on something it tastes like sour cream.
