Wash, then trim off the green tops (they can be used as a garnish). Slice off the shoots and root and peel off the tougher outer layer (if the bulb is particularly young and tender you can leave this layer on). To cook it whole, cut out the tough central core from the bottom, leaving a cone-shaped cavity, or slice if you prefer. Alternatively, chop into quarters and remove the core from each one (but not too much, or the quarters will fall apart).
Freshly cut fennel should be wrapped in damp kitchen paper, placed in a perforated bag and stored in the fridge. It will last for up to three days.
Cut into very thin slices for salads (a mandolin is good for this). Boil or steam (up to 20 minutes for a whole head, or up to 12 minutes for wedges). Roast (40-50 minutes).
