Conservo Steam Canner Tips for Firewood Stove Cooking: 5 Pro Hacks

Let’s cut to the chase: using a steam canner on a firewood stove isn’t just about repurposing old equipment; it’s about efficiency, flavor, and a whole lot of old-school charm. Here are five pro hacks to get you started.

Hack #1: Understanding Your Steam Canner and Stove

Before we even think about food, let’s get to know our tools. A steam canner, like the Conservo, is designed to create a sealed, humid environment for processing jars of food. It’s different from a water bath canner because it uses significantly less water, relying on steam to heat the jars. A firewood stove, on the other hand, is a beast of its own.

Steam Canner Basics:

• Components: Lid, base, rack, and sometimes a temperature gauge.
• Function: Heats water to create steam, which cooks and seals jars.
• Safety: Ensure your canner is in good condition, with no rust or damage.

Firewood Stove Basics:

• Types: Wood stoves come in various sizes and designs, from small camping stoves to large, indoor heating models.
• Fuel: Firewood, of course! We’ll talk about wood selection later.
• Heat Control: This is the tricky part. You’ll need to learn how to manage the fire to maintain a consistent temperature.

Why This Matters:

Understanding the capabilities and limitations of both your steam canner and firewood stove is crucial for safety and success. You wouldn’t use a sledgehammer to crack a walnut, would you? Similarly, you need to know how to adjust your fire to avoid overheating your canner or under-processing your food.

Hack #2: Mastering the Art of Firewood Selection

Firewood isn’t just firewood. The type of wood you use can significantly impact the heat output, burn time, and even the flavor of your food.

Hardwoods vs. Softwoods:

• Hardwoods (Oak, Maple, Ash): These are your go-to for cooking. They burn hotter and longer, providing a more consistent heat source. Oak, for instance, has a BTU (British Thermal Unit) rating of around 27 million per cord, while maple is around 24 million.
• Softwoods (Pine, Fir, Spruce): These burn quickly and produce a lot of smoke. They’re not ideal for cooking, as they can impart a resinous flavor to your food. Pine typically has a BTU rating of around 20 million per cord, but it burns much faster than hardwoods.

Seasoned vs. Green Wood:

• Seasoned Wood: This is wood that has been allowed to dry for at least six months, ideally a year or more. Seasoned wood has a moisture content of around 20% or less, making it burn hotter and cleaner.
• Green Wood: This is freshly cut wood with a high moisture content (often over 50%). Green wood is difficult to light, produces a lot of smoke, and doesn’t burn efficiently.

My Experience:

I once tried to cook a batch of apple butter using green pine. The result? A smoky, resin-flavored mess that went straight into the compost pile. Lesson learned: always use seasoned hardwoods for cooking.

Actionable Tips:

• Source your firewood wisely: Buy from a reputable supplier or, better yet, harvest and season your own.
• Invest in a moisture meter: This will help you determine if your wood is properly seasoned.
• Store your firewood properly: Stack it off the ground in a well-ventilated area, covered from rain and snow.

Hack #3: Temperature Control: The Holy Grail

Maintaining a consistent temperature is the key to successful steam canning on a firewood stove. This is where things can get tricky, but with practice, you’ll get the hang of it.

The Challenge:

Firewood stoves don’t have thermostats like your kitchen oven. You’re relying on your ability to manage the fire to maintain the correct temperature inside the steam canner.

The Solution:

• Start with a small fire: Don’t try to build a roaring inferno right away. Start with a small fire and gradually add more wood as needed.
• Use small pieces of wood: Smaller pieces of wood will burn more evenly and allow you to make finer adjustments to the heat.
• Monitor the temperature: Use a reliable thermometer to monitor the temperature inside the steam canner. Most steam canners have a built-in thermometer, but I recommend using a separate one for added accuracy.
• Adjust the airflow: Most firewood stoves have dampers that control the airflow. Adjusting the airflow can help you regulate the burn rate and temperature.
• Patience is key: It takes time to learn how to manage a fire. Don’t get discouraged if you don’t get it right away. Keep experimenting and you’ll eventually find the sweet spot.

Data Point:

Studies have shown that consistent temperature control during canning is crucial for preventing spoilage. Fluctuations of even a few degrees can compromise the safety of your canned goods.

Case Study:

I once worked with a local food bank to teach them how to can surplus produce using firewood stoves. The biggest challenge was temperature control. We found that using a combination of small pieces of wood, careful airflow adjustments, and constant monitoring was the most effective approach. After a few weeks of practice, the volunteers were able to consistently produce safe and delicious canned goods.

Hack #4: Adapting Recipes for Steam Canning on a Firewood Stove

Not all canning recipes are created equal. Some recipes are better suited for steam canning than others.

General Guidelines:

• High-acid foods: Steam canning is best suited for high-acid foods like fruits, jams, jellies, pickles, and tomatoes with added acid (lemon juice or vinegar).
• Low-acid foods: Low-acid foods like meats, vegetables, and soups require pressure canning to reach a safe internal temperature. Do not attempt to steam can low-acid foods on a firewood stove. The risk of botulism is too high.
• Follow tested recipes: Always use tested recipes from a reputable source, such as the USDA Complete Guide to Home Canning or the Ball Blue Book. Don’t experiment with untested recipes, as this can compromise the safety of your canned goods.

Recipe Adaptations:

• Adjust cooking times: Firewood stoves can heat up faster than electric or gas stoves, so you may need to adjust the cooking times accordingly. Start checking for doneness a few minutes before the recommended time.
• Use smaller jars: Smaller jars heat up more quickly and evenly, making them a better choice for steam canning on a firewood stove.
• Monitor the water level: Steam canning requires less water than water bath canning, but you still need to make sure there’s enough water in the canner to create steam throughout the processing time.

Real Example:

I adapted a classic apple butter recipe for steam canning on my firewood stove. I used smaller jars (pint instead of quart), reduced the cooking time by 10 minutes, and monitored the water level closely. The result was a perfectly spiced, smooth apple butter that tasted even better knowing it was cooked over a wood fire.

Cost Consideration:

While firewood is often cheaper than propane or electricity, you need to factor in the cost of your time and labor. Harvesting, splitting, and seasoning firewood takes time and effort.

Hack #5: Safety First: Preventing Accidents and Ensuring Food Safety

Safety is paramount when working with firewood stoves and canning food. A moment of carelessness can lead to serious injury or foodborne illness.

Fire Safety:

• Clear the area: Keep the area around your firewood stove clear of flammable materials.
• Use a spark arrestor: A spark arrestor will prevent sparks from escaping the stove and potentially starting a fire.
• Never leave the stove unattended: Keep a close eye on the fire at all times.
• Have a fire extinguisher nearby: Make sure you have a fire extinguisher readily available in case of an emergency.
• Install carbon monoxide detectors: If you’re using a firewood stove indoors, install carbon monoxide detectors to protect against carbon monoxide poisoning.

Food Safety:

• Follow tested recipes: As mentioned earlier, always use tested recipes from a reputable source.
• Use proper canning techniques: Follow the instructions carefully, paying attention to headspace, processing times, and sealing procedures.
• Inspect jars for proper seals: After processing, check each jar to make sure it’s properly sealed. The lid should be concave and shouldn’t flex when pressed.
• Store canned goods properly: Store canned goods in a cool, dark, dry place.
• Be vigilant: If you notice any signs of spoilage (bulging lids, off odors, mold), discard the food immediately. When in doubt, throw it out.

Troubleshooting Common Issues:

• Jars not sealing: This could be due to improper headspace, insufficient processing time, or damaged lids. Re-process the jars with new lids, or store the food in the refrigerator and use it within a few days.
• Siphoning: This is when liquid escapes from the jars during processing. It can be caused by overfilling the jars, fluctuating temperatures, or removing the jars from the canner too quickly. Adjust the headspace, maintain a consistent temperature, and let the jars cool in the canner for a few minutes before removing them.
• Broken jars: This can happen if the jars are placed directly on the bottom of the canner, if the water is too cold, or if the temperature fluctuates too rapidly. Use a rack to elevate the jars, start with warm water, and maintain a consistent temperature.

My Near Miss:

I once had a jar explode in my steam canner because I didn’t use a rack. The hot liquid splattered everywhere, and I was lucky to escape with only minor burns. It was a painful reminder of the importance of following safety precautions.
