Best Tomato Varieties: Roma, San Marzano, or other paste tomatoes hold up beautifully when canned—they’re meatier and less watery, making your winter soups and stews rich and flavorful.
Acidity Matters: Always use bottled lemon juice rather than fresh to ensure the correct acidity level for safe water bath canning. The acidity prevents spoilage and keeps your canned tomatoes shelf-stable.
Storage Tip: Store sealed jars in a cool, dark pantry for up to 18 months. If a jar doesn’t seal, refrigerate and use within a week or freeze the contents for later use.
