I always get this at our favorite local French restaurant, Paulette's, so I absolutely had to figure out a recipe for it. I use French crêpes (my specialty!), though traditional Hungarian palacsinta are a little different, I think. It takes a little bit of time to make, unless you have the crêpes already made, but it is so completely worth it! I found the actual recipe from the restaurant, and the sweet mustard sauce is from there. I cut it down from like, a gallon, which is why some of the measurements are so small. The sauce is absolutely delicious though!
