Hello all back in 2009 I used to work at Chuy's Restaurant in TX and well back then as right now as well the Creamy Jalapeño is like crack to guests, I figure I'd share the recipe which I got back then, I only recently found it in my old pictures.

Instructions

1. Open jalapeño pack and discard juice. (btw I know this sound redudant but thats what the recipe calls for lol...)
   
2. Place all ingredients in a large bowl and blend with stick blender (or regular blender)
   

PS: As you can tell this recipe isfor about a 4-5 Gallon batch, you can divide down the recipe to make a more personal size serving as this is clearly a restaurant size serving.
