Preparing for Canning

Glass jars designed for canning, free from cracks.
New lids and reusable bands to ensure a secure seal.
Canner: either a water bath canner or a pressure canner.
Essential tools like a jar lifter, ladle, and funnel.
Fresh, ripe tomatoes plus optional flavor additions (garlic, salt, basil, etc.).

Opt for firm, blemish-free varieties. Roma and San Marzano are particularly popular because of their lower moisture and rich flavor.
