193. Scotch Cock-a-leekie.—Trim two or three bunches of fine winter leeks, cutting off the roots and part of the heads, then split each in halves lengthwise, and each half into three, which wash well in two or three waters, then put them into a stewpan, with a stock previously made as directed (No. 175), and a fowl trussed as for boiling; let the whole simmer very gently at the corner of the fire for three hours, keeping it well skimmed, seasoning a little if required; half an hour before serving add two dozen French plums, without breaking them; when ready to serve, take out the fowl, which cut into neat pieces, place them in a tureen, and pour the leeks and broth over, the leeks being then partly in purée; if too thick, however, add a drop more broth or water. Should the leeks happen to be old and strong, it would be better to blanch them five minutes in a gallon of boiling water previous to putting them in the stock.
I prefer a young fowl; but, should an old one be most handy, stew it a short time in the stock before passing it. This soup will keep good several days, and would improve by warming a second time.
