I made this dressing for our weekend getaway. Mmmmm.....
I made it with low-fat buttermilk and it was still delicious. The original recipe came from my friend Bethany. It's been a while since I've had Cafe Rio, but it tasted just like I remembered it, for whatever that's worth.
1 pkg. Ranch dressing mix
2-3 tomatillos (remove papery skin), rough chop
1 cup mayo
1 cup buttermilk
½ bunch cilantro
2 cloves garlic
juice from 1 lime
½ - 1 jalapeno pepper depending on the size (remove seeds for less fire... I removed the seeds; 1/2 of a jalapeno pepper without the seeds was plenty for our uber-gringo weak-sauce palates)
Dump everything in a blender and blend until smooth. Refrigerate in air-tight container.
