Take two carrots, two onions, two turnips, a little spinach, lettuce, endive, and sorrel.Tie up together a sprig of every sort of herb you have in the garden. Boil all in water. When the hard vegetables are cooked, take out the sweet herbs, rub the whole through a fine sieve, make it not too thick by adding the water the vegetables were boiled in, add a little butter, pepper, and salt, and serve hot.
