The invention as presently conceived discloses a cooking kettle apparatus having special features to make food canning a single step process. The apparatus comprises a large diameter pour spout on the upper portion of the kettle that allows even the thickest food to flow through, and a series of interchangeable spout attachments. One spout attachment is a strainer to hold back solids as the cooked product is poured into containers. Another attachment is a straight pour spout with an air induction vent to improve the flow or liquids. The kettle has three handles about the upper portion to allow easy pouring by one person, or for two people when there is a particularly heavy batch of cooked food. The method of use provides a means by which a person can cook jams, jellies, and similar foods in the most efficient manner and with less specialized cooking items.
