Twist on Elise's Creamy Tomatillo Dressing

At our house we, too, love the Barbacoa Pork and Creamy Tomatillo Dressing. I was making it last week and I wondered if I might replace some of the fat and calories and still get a good product. I didn't want to mess things up too much so I wasn't super daring but I did replace half of the mayo with low-fat ricotta cheese and used 1% milk with 1 T of vinegar in place of the buttermilk. I also used a 1/2 tsp of cayenne pepper instead the jalepeno just because I did not have a jalepeno. Everybody seemed to enjoy it just as much! Maybe one day I'll try using plain yogurt in place of most of the mayo.
