is best to sow in September ; and grown thus the roots 
will be of good quality and ready to lift at the end of the 
summer, as they will show their maturity by the leaves 
colouring and decaying. It is well to store the roots 
when growth ceases in a cool root store or cellar, and 
not exposed to the light. They remain good a consider- 
able time, and the roots should be kept free of moisture. 
To Boil Chervil 
Wash and brush the roots, but do not cut them. 
Place them in a pan, pour over them sufficient boiling 
water to cover them, and let them simmer for about an 
hour and a half. 
To Fry Chervil 
Cook the roots as above for about an hour, then cut 
into long shreds and fry in butter.
