Home Canning 101: Beginner's Guide to Preserving Seasonal Produce

Why Home Canning Matters

Preserving seasonal produce through canning reduces food waste, saves money, and lets you enjoy summer flavors during winter months. According to the National Center for Home Food Preservation, properly canned foods retain nutrients better than store-bought alternatives.


Essential Canning Equipment

1. Jars and Lids

  • Use Mason jars with new lids for proper sealing
  • Pint (16 oz) and quart (32 oz) sizes work best for beginners

2. Processing Tools

  • Water bath canner for high-acid foods
  • Pressure canner for low-acid vegetables and meats
  • Jar lifter and funnel ($15-$40 options on WebstaurantStore)

Safety First: Avoid Botulism

  1. Acidify Properly: Add lemon juice or citric acid to tomatoes
  2. Process Time: Follow USDA-recommended processing times
  3. Altitude Adjustments: Increase processing time 1 minute per 1,000 ft elevation
