Why Learn to Preserve Food?
- Save money by buying or harvesting in-season and preserving the extra
- Reduce waste by keeping surplus food out of the trash
- Build self-sufficiency and peace of mind
- Create pantry staples that are nutritious and delicious
- Add unique, homemade flavor to your meals
Canning vs. Fermenting: What’s the Difference?
Canning uses heat to kill bacteria and seal jars for long-term shelf storage. Think fruit jams, salsa, and green beans.
Conversely, fermenting invites good bacteria (hello, probiotics!) to transform food naturally, creating tangy, zippy flavors. Think sauerkraut, kimchi, and pickles.
| Method | Shelf Stable? | Need a Fridge? | Flavor Notes |
|---|---|---|---|
| Canning | Yes | No (until opened) | Fresh, sweet, savory |
| Fermenting | Sometimes | Often | Tangy, complex, bold |
Tools You’ll Need to Get Started
For Canning:
- Water bath canner or pressure canner
- Canning jars with lids and bands
- Jar lifter and funnel
- Ladle and bubble remover
- Clean towels and labels
For Fermenting:
- Glass jars or fermenting crocks
- Weights or small jars to keep food submerged
- Clean cloth or fermentation lid
- Salt, filtered water, and flavoring ingredients
Step-by-Step: How to Can at Home (Water Bath Method)
- Prep your recipe – Choose a high-acid recipe (pickles, jam, or tomato sauce).
- Sterilize jars – Wash jars in hot soapy water or run through dishwasher; keep warm.
- Prepare food – Cook according to the recipe.
- Fill jars – Use a funnel to fill, leaving proper headspace. Remove bubbles.
- Wipe rims and seal – Clean rims and apply lids and bands.
- Process in canner – Submerge in boiling water for the recommended time.
- Cool and check seals – Let jars rest 12–24 hours. Listen for the “ping!”
- Label and store – Store in a cool, dark pantry up to 1 year.
✅ Best for: Jam, jelly, pickles, peaches, tomatoes, applesauce
Step-by-Step: How to Ferment at Home
- Chop or shred produce – Cabbage, carrots, garlic, beets… almost anything goes!
- Salt it – Sprinkle with sea salt and massage to release juices, or use a salt brine.
- Pack jars – Press tightly into jars, submerging the food in liquid or brine.
- Weigh it down – Use a fermenting weight or small jar to submerge food.
- Cover and wait – Use a cloth cover or airlock lid. Let sit at room temp 5–14 days.
- Taste and refrigerate – Move it to the fridge once it tastes tangy and delicious.
✅ Best for: Sauerkraut, kimchi, garlic honey, beet kvass, fermented salsa
Tips for Success
- Always use clean equipment and high-quality ingredients
- Label everything with the date you made it
- When in doubt, toss it out (bad smells, colors, or mold = not worth the risk)
- Fermentation speeds up in warmer temperatures and slows in cool rooms
- Use kosher or sea salt (not iodized) to avoid interfering with fermentation
Flavor Boosters to Try
| Canning Add-Ins | Fermenting Add-Ins |
|---|---|
| Cinnamon, cloves | Ginger, turmeric root |
| Vanilla bean | Red pepper flakes |
| Lemon zest | Garlic, mustard seeds |
| Fresh herbs | Dill, bay leaves |
Storage & Shelf Life
- Canned goods: Store in a cool, dry pantry. Use within 1 year. Refrigerate after opening.
- Fermented foods: Store in fridge once tangy and bubbly. Most of the last 3–6 months.
How to Know It’s Gone Bad
| Signs to Toss | Common in Canning? | Common in Fermenting? |
|---|---|---|
| Mold growth | Yes | Yes |
| Off smells | Yes | Yes (fermented foods should smell sour, not rotten) |
| Jar did not seal | Yes | N/A |
| Slimy texture | No | Sometimes (means over-fermentation) |
FAQs
Q: Do I need a pressure canner?
A: Only for low-acid foods like meats, green beans, or soups.
Q: How do I know if fermentation is working?
A: You’ll see bubbles, a color change, and a pleasantly sour smell. That’s good bacteria doing their job!
Q: Can I use table salt for fermenting?
A: Avoid it—it often contains anti-caking agents that can affect fermentation.
