Introduction
Canning is a time-honored food preservation technique that allows you to enjoy fresh produce throughout the year. By sealing food in airtight containers and heating them to high temperatures, canning kills bacteria and other microorganisms, preventing spoilage and extending shelf life significantly. Whether you're a seasoned home cook or a beginner looking to get started with canning, this comprehensive guide will provide you with everything you need to know to can foods safely and effectively.
