Who We Are and What We Do

Welcome! The UC Master Food Preservers of Sonoma County are trained volunteers who teach safe, validated home food preservation to our communities.

Our UC Master Food Preserver mission is to keep Californians safe and well as they use culturally appropriate, research-based practices to safely preserve food in the home, reducing food waste, increasing food security, and providing engaging ways for Californians to explore healthly food.

Events

At fun classes and workshops, we teach you step-by-step, safe methods to preserve food at home:

  • Food safety
  • High-acid preservation - boiling water and steam canning
  • Making jams and jellies
  • Pickling
  • Dehydrating
  • Low-acid preservation - pressure canning
  • Cold storage
  • ...and much more!
