Chervil: Subtlety is key when using chervil in cooking. Although chervil will never dominate a dish, many cooks use it to enhance the flavours of other herbs accompanying it in recipes. Chervil is an important inclusion in the traditional French fines herbs blend of tarragon, parsley, chives and chervil. Chervil complements scrambled eggs and omelettes, cream cheese and herb sandwiches, salads and even mashed potatoes.
