English historical translation of Molokhovets recipe No. 3620 from the 1901 Russian cookbook, retaining original methods and measures.
Place the rancid butter in a saucepan, cover with as much water as possible and boil for a time.
Cool, decant the water, remove the butter, wash in cold water and salt.
Historical editorial note: Boiling and washing rancid or spoiled butter do not reliably restore its food safety.
