What do I think of at holiday time when it comes to soup? French Onion soup, hands down. I love the rich taste of the caramelized onions (and I use a lot of them), red wine, sherry and rich beef broth. Top it with a thick piece of toasted crusty bread topped with ooey, goey melted Gruyere cheese, nothings better. It’s something you get in restaurants, but how do you…
