Fennel bulb
Like Marmite, fennel is something that you either love or hate - its strong aniseed flavour leaves no room for the middle ground. From the same family as the herb and seed of the same name, it's also known as Florence fennel, finocchio, or sweet fennel, is very popular in Italian cookery, and has a bulb-like shape that looks a little like a heavy-bottomed celery.
When eaten raw, the texture is crisp and the flavour is quite assertive and anisseedy. Cooked, it's softer and more mellow.
Fennel is thought to aid digestion.
Availability
All year round, but it's best from the start of June to the end of September.
Choose the best
If possible, go for the smaller, young bulbs, as they're more tender. They should look white, with no blemishes, and feel heavy for their size. The feathery green tops should be fresh and bright, with no yellowing.
Store
Fresh 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.
Prepare
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).
Broccoli
Like cabbage and cauliflower, broccoli is a brassica and is sometimes known by its Italian name, calebrese. It has tight clusters of deep green buds and thick, edible stems and was developed from the more loosely packed purple sprouting broccoli. There's little to choose between the two in terms of flavour or nutrition - and broccoli is high in vitamin C.
Availability
All year round, but at its best from the end of July to the end of October.
Choose the best
Go for firm, bright green, undamaged heads (if it's yellow its already past its peak) and firm stalks. As broccoli deteriorates faster when in contact with the air, supermarkets often wrap it in cellophane - always choose the unwrapped type if you can as, if it still looks good, you can be sure that it has been recently picked.
Store
In an airtight bag in the fridge.
Prepare
Trim any woody stem ends or tough leaves with a knife. Divide into small, individual florets, each with a short stem, and diagonally slice the thicker stems. Rinse under cold water. Broccoli boils or steams in 3-6 minutes, depending on the size of floret. In stir-fries, cook it for a couple of minutes, until tender
