Rocket is a very 'English' leaf, and has been used in salads since Elizabethan times. It has a strong, peppery flavour, and the leaves have a slight 'bite' to them. If you see 'rucola' or 'arugula' for sale or on a restaurant menu - it's the same thing.
Available year-round in supermarkets. Rocket is incredibly easy to grow, in fact, it could take over your whole veg patch.
Choose the best
Look for perky dark-bright green leaves. Avoid those that look slimy, yellowed or browning, as they're past their best.
Just rinse and go.
Store in the bottom part of your fridge, in brown paper or a perforated bag. It will last for a maximum of 2 days.
Mix with other salad leaves; throw a handful on top of pasta or a pizza.
