Recipe Notes / Tips
My favorite mandoline is the Benriner. Buy at your favorite Asian grocery or online.
To slice the fennel, take a small slice off the very bottom, lop off all but about 4-inches of the frond stems and cut the bulb in half from top (frond end) to bottom (root base). I usually remove the outermost layer and discard, but if it looks in good shape, give it a good wash and leave it. If the core is large, remove it by cutting out a small wedge from each half. Slice on mandoline, starting root base down, frond ends up—be careful not to cut your fingers!
