I recently acquired a shopping bag full of fresh wild fennel, hand picked near Salaparuta. The wild fennel is the key to the magnificent dish from Palermo called "Pasta con le sarde" (pasta with sardines). There is no substitute for the fennel. (BTW, the other ingredients are fresh sardines, currants, pignoli, saffron, onion, anchovies, tomatoe paste, and olive oil). How do I store the fennel? I was thinking of blanching and freezing it, with the blanching liquid. The blanching liquid is used to loosen the sauce. Of course, it would be easier to freeze it fresh. Can I do that without damaging the fennel? Thanks!
