However, many home cooks wonder if this delectable spread can be preserved through pressure canning. This blog post delves into the intricacies of pressure canning hummus, providing you with all the necessary information to make informed decisions about preserving your homemade hummus.
Understanding Pressure Canning: A Primer
Pressure canning is a safe and effective method of preserving low-acid foods like hummus. It involves using a specialized pressure canner to heat food to a high temperature (240°F or 116°C) under pressure, killing harmful bacteria and spores that can cause spoilage. This process ensures that the food remains safe for consumption for extended periods.
Can Hummus Be Pressure Canned?
Yes, hummus can be pressure canned. However, it is important to note that pressure canning hummus requires precise adherence to specific guidelines to ensure its safety. The high moisture content and low acidity of hummus make it susceptible to spoilage if not processed correctly.
Step-by-Step Guide to Pressure Canning Hummus
Materials:
- Pressure canner
- Canning jars and lids
- Hummus
- Lemon juice or citric acid
- Salt
Instructions:
1. Prepare the Hummus: Ensure the hummus is fresh and free of any signs of spoilage. Add lemon juice or citric acid and salt to adjust the acidity to a pH of 4.6 or below.
2. Fill the Canning Jars: Fill the sterilized canning jars with hummus, leaving 1-inch headspace.
3. Remove Air Bubbles: Tap the jars gently to remove any trapped air bubbles.
4. Wipe the Rims: Wipe the rims of the jars with a clean cloth to remove any hummus residue.
5. Place the Lids: Place the lids and rings on the jars and tighten them finger-tight.
6. Process in the Pressure Canner: Place the jars in the pressure canner and process them at 10 pounds of pressure for 75 minutes for pints and 90 minutes for quarts.
7. Cool and Store: After processing, allow the pressure canner to cool completely before removing the jars. Store the canned hummus in a cool, dark place for up to a year.
Safety Considerations
- Follow the Recipe: It is crucial to follow the recipe and processing times precisely to ensure the safety of the canned hummus.
- Use Acid: Adding lemon juice or citric acid is essential to adjust the acidity of the hummus to a safe pH level.
- Check for Spoilage: Before consuming canned hummus, check for any signs of spoilage, such as bulging lids, leakage, or a foul odor.
- Discard Spoiled Hummus: If any signs of spoilage are detected, discard the hummus immediately.
Troubleshooting Common Problems
- Hummus is too thick: If the hummus is too thick to pour into the jars, thin it with a little water or vegetable broth.
- Jars are not sealing: Ensure the jars are clean and the lids and rings are tightened properly. If the jars still do not seal, the hummus may not be acidic enough. Add more lemon juice or citric acid and reprocess.
- Hummus is discolored: Discoloration can occur due to oxidation. To prevent this, add a small amount of ascorbic acid (vitamin C) to the hummus before canning.
Benefits of Pressure Canning Hummus
- Extended Shelf Life: Pressure canning significantly extends the shelf life of hummus, allowing you to enjoy it for months.
- Convenience: Canned hummus is convenient to store and transport, making it perfect for picnics, camping trips, or emergencies.
- Reduced Food Waste: Pressure canning hummus helps reduce food waste by preserving excess hummus that might otherwise go to waste.
Alternatives to Pressure Canning Hummus
If pressure canning is not an option, there are alternative methods for preserving hummus:
- Refrigeration: Fresh hummus can be stored in the refrigerator for up to 5 days.
- Freezing: Hummus can be frozen for up to 3 months.
- Oil Layer: Covering hummus with a layer of olive oil can help prevent spoilage for up to 2 weeks in the refrigerator.
