This is a tortological name, as achard invariably contains vegetables and lemon. Achard is a strong spiced pickle containing carrots, peppers, cucumbers, string beans, cauliflower florets, lemons and spices.
A land snail, or escargot, from China or Indonesia or, according to other reports, from the East coast of Africa. Less prized than other varieties for eating, it was introduced into France in the early 20th century and in New Caledonia in 1972, where it has become invasive and damaging to native species.
Water parsnip. Both the leaves and flowers of this plant may be used for food though I have read that it is toxic to mammals, which doesn’t sound very promising. It grows in damp boggy places.
Lovage. A large unwieldy herb. Pick the stems off the leaves, tie them and hang them to dry for about 3 days. When crisp, crumble the leaves and store. Good in hotpots. Lovage seeds are used mainly in Indian cooking, and are from a plant of the caraway family. The greenish-brown seeds are a little larger than celery seeds and have a strong aroma of rather coarse thyme. All parts of the plant can be used.
Alexanders or black lovage. A celery-flavoured plant. Stems can be prepared as a vegetable and served with butter and black pepper.
