Today it was Fennel.
Here's a copy of the recipe I used this evening. I only had 2 large bulbs of Fennel, so I substituted with a pound of sliced mushrooms. Yes, it really did take SEVEN cups of broth (I used chicken bullion). This made an enormous stock pot over half full of Risotto. I have a family of 6 that put a good dent in it, but we did have left overs. Give it a try - and let me know how you liked your first fennel experience!
