This is DEVINE! I followed the recipe exactly with the exception that I left out the celery, as I don't care for it. This dish is creamy, savory, and comforting - but best of all, SO EASY!!! I will make this again, and you should too if you haven't yet, larchie!!! Thank you so much, I LOVE IT! Be sure not to add any more mustard than it calls for, or it becoms bitter. I made it a second time and added too much mustard. Add some lemon juice and it helps to neutralize this.
