Hi, I do love this recipe and I have made it 3 times now (this will be my 4th). My question is, do you have any idea how many oz of fennel is the right amount? Fennel bulbs vary so much and I agitate over how much to use. This is doubled by the fact that I am, indeed, doubling the recipe for 12 people. I did this last year, but again, so much fret over how much to use. If you could even provide an idea of how large your fennel bulbs are, that would be good. My bulb tonight was 5 inches in length and 3 inches in width. Thank you!
