My absolute favorite Tex-Mex restaurant is Chuy's. They serve a Creamy Jalapeno dip (Creamy "J") and since I moved away from TX, I crave it often. I did a search for it and tried out one of the copycat recipes, and this tastes really close! I like to use lowfat stuff in it and eat it over refried Beans (and other mexican dishes), but with refried beans is a quick snack and it really gives them a kick! You can adjust the heat by adding less jalapenos.
CREAMY JALAPENO SAUCE
3/4 C low fat mayo
3/4 C buttermilk (low fat...regular milk can be subbed)
1 packet hidden valley ranch dry dressing mix
1 (4 oz) can sliced jalapenos, drained)
cilantro leaves, fresh (to taste)
1 t. salt
1 t. lime juice
1 t. garlic powder
I just throw it all in the blender and add the cilantro last. I put a lot of cilantro in it and just keep tasting it until I get it right!
