Creme Fraiche and Hummus Recipe (Sort Of)

A good chef friend of mine shared two quick recipes with me at the farmers market one day.  I scribbled notes down and wanted to be sure I documented them somewhere safe.  I haven't tried the recipes yet, nor are they very descriptive; but one day time permitting I will try my hand at these and then post a real recipe for viewers at home to try.

Crème Fraiche Recipe (or maybe this was the recipe for Cream Cheese)

1 Quart Heavy Cream - of course we will use Snowville Dairy Heavy Cream until we have our own cow here on the farm. 
2 T Buttermilk

Stir the two ingredients.
Set on your counter for 2 days until it turns yellow.
Refrigerate.

Hummus Recipe

2 T Tahini
Garbanzo Beans
Lemon Juice
Olive Oil
Salt
Boiling Water

Add the first 5 ingredients in a food processor, slowly add the boiling water while blending.

Now I know I won't lose these notes.  I will let you know when I try it.
