Rue

A bitter perennial herb with small grey-green leaves and a pungent aroma. It has a reputation for being dangerous and it should be avoided by pregnant women. In small quantities it is quite safe and adds necessary bitterness to sweet dishes in Roman food. It is not regularly available as a culinary herb and the only sure way to obtain a supply is to grow your own. It is pretty much indestructible and establishes itself well in a sunny site. Many garden-centres sell it and, as you will only require a small amount in any dish, it should not take long to be ready. It should be picked with great care as a chemical in the leaves can react with sunlight and, if touched, can burn the skin. Pick in the shade and, if you think you are susceptible, it would be best to avoid the task or get some one else to pick it for you. Out of the sun it is generally harmless unless you have particularly sensitive skin.
