good broth or stock, 2 oz. of butter. _Mode_.--Boil the potatoes, well drain them, and pound them smoothly in a mortar, or beat them up with a fork; add the stock or broth, and rub the potatoes through a sieve. Put the puree into a very clean saucepan with the butter; stir it well over the fire until thoroughly hot, and it will then be ready to serve. A puree should be rather thinner than mashed potatoes, and is a delicious accompaniment to delicately broiled mutton cutlets. Cream or milk may be substituted for the broth when the latter is not at hand. A casserole of potatoes, which is often used for ragoûts instead of rice, is made by mashing potatoes rather thickly, placing them on a dish, and making an opening in the centre. After having browned the potatoes in the oven, the dish should be wiped clean, and the ragout or fricassée poured in. _Time_.--About 1/2 hour to boil the potatoes; 6 or 7 minutes to warm the purée. _Average cost_, 4s. per bushel. _Sufficient_.--Allow 1 lb. of cooked potatoes for 3 persons. _Seasonable_ at any time. [Illustration: SWEET POTATO.] VARIETIES OF THE POTATO.--These are very numerous. "They differ," says an authority, "in their leaves and bulk of haulm; in the colour of the skin of the tubers; in the colour of the interior, compared with that of the skin; in the time of ripening; in being farinaceous, glutinous, or watery; in tasting agreeably or disagreeably; in cooking readily or tediously; in the length of the subterraneous _stolones_ to which the tubers are attached; in blossoming or not blossoming; and finally, in the soil which they prefer." The earliest varieties grown in fields are,--the Early Kidney, the Nonsuch, the Early Shaw, and the Early Champion. This last is the most generally cultivated round London: it is both mealy and hardy. The sweet potato is but rarely eaten in Britain; but in America it is often served at table, and is there very highly esteemed. POTATO RISSOLES.
