It's a Salsa that thinks it's Guacamole! Another great salsa recipe using those wonderful little tomatillo tomatoes. This recipe combines the sweetness of the tomatillos with the heat of the serrano chili pepper. If you don't want a lot of heat use only half a pepper.
Never serve naked veggies again! Very flexible recipe, if you like your cheese sauce more runny just add more cream. If you like a thicker sauce to use for as a dip, reduce the cream by half.
