Sift onto a table one pound of flour; make a hollow space in the centre, and place therein six egg yolks, half a gill of lukewarm water, one ounce of fresh butter, and half a saltspoonful of salt. Knead these thoroughly for five minutes; then mix in the flour gradually, and knead again for five minutes. Pile up the paste into a lump, flour the table slightly, and use the left hand to press the paste down in the centre, and with the right bring up the edges all around. Continue to repeat this for five minutes. Roll the paste into a ball, put it on a dish, cover with a napkin, and set it in a cool place to rest for fifteen minutes. Roll it out to the thickness of a fifty-cent piece. With a knife cut it into strips two inches wide, and from these, beginning at the end of each, shred it with the knife into narrow pieces resembling matches. Leave these to dry slightly on a floured board for thirty minutes, and they will be ready for use.
