Best hollandaise sauce - ever. Love the tanginess. I last served it with spicy Italian sausage instead of the bacon (which is also fabulous) over toasted croissants. Fab. The tobasco in the sauce perfectly matched the spice of the sausage which was mellowed just a tad by the buttery croissant. I love this recipe and every time I make it for someone they want the recipe themselves. Can't go wrong.
