We were served this at a dinner party. The host obtained the recipe from a restaurant I believe is called "Miguel's Cocina". This luscious sauce is perfect as a dip for fresh veggies, tortilla chips or better yet, potato chips! It's also an irresistible topping for baked potatoes. Because it's simply a flavored, upscale white sauce, the sky's the limit here! For chicken base, I use the "paste" type soup base, and also add a pinch of salt to the roux. Adjust the jalapenos and juice to taste.
