Why Do We Use Canning Racks Anyway?
Before we bypass them, it’s helpful to understand the purpose of a canning rack. These racks typically sit at the bottom of your canning pot and serve several important functions:
- Prevent Breakage: Jars directly touching the hot bottom of the pot can experience extreme temperature differences, leading to thermal shock and potential cracking or breaking. The rack creates a barrier.
- Ensure Water Circulation: By elevating the jars, the rack allows water to circulate freely underneath and around them. This is crucial for even heat distribution, which is vital for safe processing.
- Keep Jars Upright and Stable: A rack helps to hold your jars steady during the boiling or pressure canning process, preventing them from tipping over or bumping into each other and potentially breaking.
So, our goal with any alternative is to achieve these same benefits: elevation, circulation, and stability.
Clever Alternatives When You Can Can Without a Canning Rack
Don’t let a missing canning rack stop your preserving plans! Here are some excellent, safe substitutes you likely already have around your home:
1. Mason Jar Rings (Bands)
This is arguably the most popular and easiest alternative. Simply place several unused canning rings (the screw bands, not the flat lids) on the bottom of your pot. Arrange them in a single layer, close together, to create a stable platform for your jars. Ensure they cover most of the bottom surface where your jars will sit. The open centers allow for perfect water circulation.
2. Kitchen Towels
A thick, clean kitchen towel (or two) can work wonders. Fold it into a thick pad and place it at the bottom of your canning pot. Make sure it’s thick enough to provide good cushioning and elevation – at least ½ to 1 inch. The fabric will cushion the jars and allow water to seep through, ensuring circulation. Avoid using paper towels as they can disintegrate. Choose a towel you don’t mind getting stained or one dedicated to canning.
3. Silicone Mats
If you have silicone baking mats or trivets, these can be perfect! Silicone is heat-resistant and provides excellent cushioning. Cut a silicone mat to fit the bottom of your pot, or use a few silicone trivets spaced out. Their non-slip surface also adds extra stability for your jars. Ensure they are food-grade silicone and rated for high temperatures.
4. Wire Cake Cooling Racks
A sturdy wire cooling rack designed for baking can be repurposed as a canning rack. Look for one that fits snugly into your canning pot without being too small or too large. If it has feet, that’s a bonus for elevation. Make sure it’s made of stainless steel or another rust-proof, heat-safe material that won’t leach chemicals.
5. Aluminum Foil Balls
In a pinch, you can create a makeshift rack using aluminum foil. Crumple several sheets of heavy-duty aluminum foil into balls, each about 2-3 inches in diameter. Arrange these foil balls on the bottom of your pot to create a stable, elevated base for your jars. Make sure there are enough balls to support all your jars evenly and prevent direct contact with the pot bottom.
6. Vegetable Steamer Baskets
Many collapsible metal vegetable steamer baskets are perfect for this. Place the steamer basket (legs down) at the bottom of your pot. The perforations allow for excellent water circulation, and the legs provide elevation. Ensure it’s made of stainless steel and is stable enough to hold the weight of your jars.
What to Look For in a Canning Rack Alternative
When choosing an alternative, keep these critical safety points in mind:
- Heat Resistance: The material must be able to withstand boiling water (212°F or 100°C) or higher temperatures if pressure canning, without melting, deforming, or leaching chemicals.
- Stability: It must provide a stable, flat surface for your jars to sit on, preventing them from tipping or rocking during processing.
- Elevation: It needs to lift the jars at least ½ inch off the bottom of the pot to prevent direct contact and allow for water circulation.
- Water Circulation: Whatever you use, water must be able to flow freely underneath and around the jars for even heating.
- Non-Reactive: The material shouldn’t react with the water or food, or leach harmful substances. Stainless steel, silicone, and clean cotton towels are generally safe choices.
How to Can Safely with a DIY Rack
The process is almost identical to canning with a standard rack:
- Prepare Your Rack Alternative: Place your chosen alternative (rings, towel, silicone mat, etc.) at the bottom of your clean canning pot.
- Add Hot Water: Carefully place your hot, filled jars onto the alternative rack. Ensure they are not touching each other or the sides of the pot. Fill the pot with hot water, covering the jars by at least 1-2 inches.
- Process Jars: Cover the pot with a lid and bring the water to a rolling boil (for water bath canning) or follow your pressure canner instructions. Process for the time specified in your recipe.
- Cool Safely: Once processing is complete, turn off the heat and let the jars sit in the hot water for 5 minutes before carefully removing them. Place them on a towel on your counter, spaced apart, to cool undisturbed for 12-24 hours.
FAQs About Canning Without a Rack
Is it really safe to can without a canning rack?
Yes, as long as you use a suitable alternative that provides elevation, stability, and allows for proper water circulation, it is perfectly safe. The critical part is preventing direct contact with the pot bottom and ensuring even heating.
Can I use these alternatives for pressure canning?
Absolutely! The same principles apply. For pressure canning, ensure your chosen alternative is sturdy, heat-resistant, and won’t impede the pressure canner’s vent or safety valves. Silicone mats, metal rings, or foil balls are generally excellent choices. Towels might absorb too much water and reduce the available steam space, so they are less ideal for pressure canning.
What’s the main purpose of elevating the jars?
Elevating the jars serves two primary purposes: preventing direct contact with the potentially scorching-hot bottom of the pot (which can cause breakage) and allowing hot water to circulate completely around each jar, ensuring even heat penetration and safe food preservation.
Happy Canning!
