Chervil Anthriscus cerefolium
The most fragile herb in the kitchen. Thirty seconds of heat and it is gone, which is why almost no one outside French cooking bothers with it.

In the kitchen
Add it at the table
Chervil goes on the finished plate, after the food has stopped cooking. Even residual heat in a sauce takes it. This is not fussiness — the difference is obvious side by side.
Use whole sprigs
Chopping bruises it and the leaf is already fine enough. Pick the feathery sprigs off the stem whole and scatter them. They also look better than almost any other herb.
Fines herbes
With parsley, chives and tarragon it forms the classical French quartet, where its job is to soften and round the other three. In an omelette aux fines herbes it is the one most cooks omit and most miss.
Beyond the kitchen
AN EASTER HERB
Chervil carried long association with Lent and Easter in parts of Europe, appearing in Grüne Soße in Frankfurt and in Dutch kervelsoep, both traditionally eaten around Maundy Thursday when it is at its spring best.
GRÜNE SOßE
Frankfurt's green sauce is legally defined around seven specific herbs, chervil among them, and the city takes it seriously enough to hold festivals and erect a monument to it.
A DANGEROUS FAMILY
Chervil is in the Apiaceae, the same family as poison hemlock and fool's parsley. Cultivated chervil is entirely safe; wild foraging in this family is not, and is a frequent source of serious poisoning.
IT FAVOURS SHADE
Unusually among herbs, chervil wants cool and partial shade and will bolt in full sun. It is one of the few useful things to grow in a shaded corner where basil and rosemary would sulk.
A longer history
Chervil is native to the Caucasus and western Asia and was spread through Europe by the Romans, who took it as far as Britain. It appears in classical writing on gardens and in Charlemagne's Capitulare de villis, which puts it among the standard plants of the early medieval European kitchen garden.
Its association with spring and with Lent ran through European folk practice for centuries, and it survives in that role in regional dishes — Frankfurt's Grüne Soße, Dutch and Belgian kervelsoep, and various Maundy Thursday green dishes across the Low Countries and Germany.
It never industrialised. Because it wilts within days, loses its aroma to heat, and cannot be usefully dried, chervil resisted every part of the modern food supply chain. That is why it remains a herb of home gardens and serious restaurant kitchens and is almost absent from supermarkets.
