May is officially asparagus season in Britain. Crunchy and fresh, asparagus is one of our most delicious vegetables, well worth the wait until spring. It’s also a vegetable that dehydrates quite quickly – hence those stringy, bitter asparagus tips in the supermarkets all year round, flown in from South America and Spain. British asparagus is surprisingly juicy and the flavour unique. From the lily family, alongside onions and leeks, asparagus has a bud-like head and a long stalk, both of which are edible.
