It is among the most famous french recipes that you find Buerre blanc sauce aka butter sauce. Goes well with seafood and if you ask me a vegetarian, there is a hell a lot of other dishes that it can enhance the taste of. My daughter loves this on ravioli, pasta and we love it as an additional sauce to make our wheat bread sandwiches and falafels taste better without being too much!!!
Use margerine and soy milk to make it vegan.
Get Fit Facts: An average butter sauce has a whopping 600-1500 calories in itself. Plus the main course that you dribble it on takes you far from the needed 2000 calorie diet a day. Hence, the attempt to reduce the butter sauce to a meager 130 calories so you don't over blow a whole day's good eating:-)
