🥔 Why Can Potatoes?

✅ Long Shelf Life – Lasts 1-2 years when stored properly.
✅ Convenience – Ready-to-use in meals, saving prep time.
✅ Nutrient Retention – Preserves vitamins and minerals.
✅ Cost-Effective – Great for bulk storage or homegrown harvests.

⚠️ Safety First!

Potatoes are low-acid foods, meaning they must be pressure-canned (not water-bathed) to prevent botulism.
🔹 Always use a pressure canner (not a pressure cooker).
🔹 Follow tested guidelines (USDA or National Center for Home Food Preservation).
🔹 Check jars for proper seals before storage.

🛠️ What You’ll Need

Ingredients

✔ Fresh potatoes (Yukon Gold, Russet, or Red work best)
✔ Canning salt (optional, for flavor)
✔ Water

Equipment

✔ Pressure canner (must be used for potatoes)
✔ Canning jars (quart or pint-sized, Mason/Ball jars)
✔ Lids & bands (new lids for best sealing)
✔ Jar lifter, funnel, bubble remover
✔ Large pot (for pre-cooking potatoes)
✔ Knife, peeler, & cutting board

📝 Step-by-Step Canning Process

1️⃣ Preparing the Potatoes

• Wash & Peel – Scrub potatoes thoroughly, then peel (optional for rustic texture).

• Cut – Cube or slice into 1-2 inch pieces (uniform size ensures even cooking).

• Pre-Cook – Boil for 2 minutes to remove excess starch (prevents cloudiness).

• Drain & Rinse – Use cold water to stop cooking.

2️⃣ Packing the Jars

• Hot Pack (Recommended) – Fill jars with hot potatoes, leaving 1-inch headspace.

• Add Salt (Optional) – ½ tsp per pint, 1 tsp per quart.

• Cover with Boiling Water – Maintain 1-inch headspace.

• Remove Air Bubbles – Slide a tool around edges to release trapped air.

• Wipe Rims – Ensure clean sealing surface.

• Secure Lids – Finger-tight (not too tight!).

3️⃣ Pressure Canning

• Load Canner – Place jars on rack with 2-3 inches of water.

• Vent Steam – Let steam escape for 10 minutes before sealing.

• Process Time:

  • Pints: 35 mins (at 10 psi for weighted gauge, 11 psi for dial gauge).

  • Quarts: 40 mins (same pressure).

• Cool Naturally – Wait until pressure drops before opening.

4️⃣ Checking Seals & Storing

• Test Seals – Press center of lid; if it doesn’t pop, it’s sealed!

• Label & Store – Remove rings, wipe jars, and store in a cool, dark place.

💡 Storage & Usage Tips

✔ Shelf Life: 1-2 years (best quality within 12 months).
✔ Usage Ideas: Soups, stews, fried potatoes, mashed potatoes.
✔ If Unsealed: Refrigerate & use within 3 days or reprocess within 24 hours.
