Scrape and peel the vegetables; slice up all these very thinly, and put them into a two-gallon pot, with the butter, parsley, chervil, and thyme, and fill up with water or pot liquor, if you happen to have any; season with pepper and salt, and put the whole to boil very gently on the fire for two hours; at the end of this time the vegetables will be done to a pulp, and the whole must be rubbed through a colander with a wooden spoon, and afterwards put back into the pot and stirred over the fire, to make it hot for dinner.
