Celeriac is cooked in the same manner as Beet, and requires about the same length of time.  The stems, bulbs, or roots (for the knobs, which are true stems, are known by various names) are trimmed, washed, and put into boiling water without salt or any flavouring, and kept boiling until quite tender; they may then be pared, sliced, and served with white sauce, or left uncut to be sliced up for salads when cold.

==Cichorium Intybus==

A valuable addition to the supply of winter and spring roots.  When stewed and served with melted butter, Chicory bears a slight resemblance to Sea Kale.  More frequently, however, it is eaten in the same manner as Celery, with cheese, and it also makes an excellent and most wholesome salad.  All the garden varieties have been obtained from the wild plant, and some of the stocks show a decided tendency to revert to the wild condition.  It is therefore important to sow a carefully selected strain, or the roots may be worthless for producing heads.

Seed should be sown in May or June, in rows one foot apart, and the plants thinned out to about nine inches in the rows.  The soil must be deep and rich, but free from recent manure, except at a depth of twelve inches, when the roots will attain the size of a good Parsnip.

In autumn the roots must be lifted uninjured with the aid of a fork, and only a few at a time, as required.  After cutting off the tops just above the crown, they can at once be started into growth, and it is essential that this be made in absolute darkness.  French growers plant in a warm bed of the temperature suited to Mushrooms, but this treatment ruins the flavour, and has the effect of making the fibre of the leaves woolly.  It is far simpler and better to put the roots into a cellar or shed in which a temperature above the freezing point may be relied on, and from which every ray of light can be excluded.  They can be closely packed in deep boxes, with light soil or leaf-mould between.  If the soil be fairly moist, watering will not be necessary for a month, and had better not be resorted to until the plants show signs of flagging.  Instead of boxes, a couple of long and very wide boards, stood on edge and supported from the outside, make a convenient and effective trough.  The packing of the roots with soil can be commenced at one end, and be gradually extended through the entire length, until the part first used is ready for a fresh start.  Breaking the leaves is better than cutting, and gathering may begin about three weeks after the roots are stored.  From well-grown specimens, heads may be obtained equal to a compact Cos Lettuce, and by a little management it is easy to maintain a supply from October until the end of May.  The quantity of salading to be obtained from a few roots is really astonishing.
