Creamy Cilantro-Serrano Sauce

We ran this sauce all month in July 2011 and it was a hit.
It's really easy to make and it tastes as good on a salad 
as it does in fajitas or just dipping a chip in it.

1 Cup mayonnaise
1/3 Cup cilantro leaves
5-6 serrano peppers
3 cloves garlic
Salt and pepper to taste
1/2 Cup half-and-half

Now this is my kind of recipe.  Put it all in a blender
and turn it on.  Once it's blended, turn it off and stick 
your finger in to taste it.  If it's not spicy enough, 
add another serrano.  If you want it to be more of a dressing, 
add a little more half-and-half.  Refrigerate if you don't 
eat it all in one sitting.  ENJOY!
