Canning is a popular way to preserve fruits and vegetables for long term storage. The canning process allows you to enjoy garden-fresh produce all year round. Many people wonder if you can safely can green beans and carrots in the same jar. Let’s take a closer look at the do’s and don’ts of canning these two vegetables together.
Can You Can Green Beans and Carrots Together?
The short answer is yes, you can can green beans and carrots together. However, there are some important guidelines to follow when canning mixed vegetables to ensure safety.
The USDA recommends only canning vegetables with similar pH levels together. The pH of a food is a measure of its acidity or alkalinity. Green beans and carrots both fall into the low-acid category, with pH levels between 4.6 and 5.2. This means their pH levels are similar enough to allow canning them together.
You should avoid canning high-acid foods, like tomatoes or pineapple, with low-acid foods. The differing pH levels can create an environment where the growth of dangerous bacteria is not adequately controlled by the canning process. Botulism spores are a particular concern.
Steps for Canning Green Beans and Carrots
Follow these basic steps for safely canning green beans and carrots together:
- Wash and trim green beans, removing stems and tails. Peel and slice carrots. Keep vegetables separate at this stage.
- Blanch the vegetables to deactivate enzymes and soften cell structure. Green beans should be blanched for 3 minutes and carrots for 5 minutes.
- Load prepared raw pack jars with green beans and carrots in your desired proportions. Leave 1-inch headspace.
- Add water, salt, lemon juice, or other seasonings to the jars. Vegetable juice from blanching can also be used as canning liquid.
- Remove air bubbles and adjust headspace if needed. Wipe rims and apply lids and bands.
- Process pint or quart jars in a pressure canner at 11 PSI for the appropriate time based on your altitude. Refer to a canning guide for specific timing.
- Allow jars to cool undisturbed for 12-24 hours. Check seals, label, and store.
Benefits of Canning Green Beans and Carrots Together
Some of the benefits of canning these vegetables together include:
- Convenience – You can pull one jar off the shelf for a meal instead of two separate ones.
- Saves jar space – Mixing vegetables allows you to maximize the number of jars from your garden harvest.
- Nutrition – Enjoy a serving of green beans and carrots in one bite for a nutritional power duo.
- Flavor – The flavors of green beans and carrots complement each other nicely.
Choosing Vegetables for Canning
When choosing vegetables to can together, follow these guidelines:
- Select vegetables of similar density that will cook at the same rate. Cut harder, denser vegetables into smaller pieces.
- Choose vegetables that are in peak freshness and flavor. Avoid old or damaged produce.
- Stick to vegetables with a similar pH for safe acidity levels. Refer to a canning guide.
- Make sure flavors complement each other. Some examples are carrots/peas, green beans/potatoes, corn/lima beans.
- Keep an eye on texture. Don’t pair a crunchy vegetable with something soft and creamy.
Canning Liquid Options
The liquid in the jar plays an important role in preserving canned vegetables. Here are some options:
| Canning Liquid | Notes |
|---|---|
| Water | Plain water is the most common canning liquid for vegetables. Make sure to add salt or lemon juice for flavor and acidity. |
| Broth | For added flavor, substitute vegetable, chicken, or beef broth for water. |
| Tomato juice | The natural acidity of tomato juice helps control bacteria. Use for canning low-acid vegetables. |
| Vegetable juice | Juice reserved from blanching vegetables provides great flavor. Make sure to add lemon juice or vinegar for proper acidity. |
Choosing Other Ingredients
Spices, herbs, seasonings, and other ingredients can be added to canned vegetables to suit your recipe needs:
- Salt – 1/2 teaspoon per pint is commonly used. Helps season and preserve.
- Sugar – A teaspoon of white or brown sugar can help offset acidity.
- Vinegar – Cider or white vinegar adds acidity. Use 2 tablespoons per quart.
- Lemon juice – The high acidity level makes it perfect for canning. Use 2 tablespoons per quart.
- Spices – Whole allspice, bay leaves, peppercorns, etc. can be added for flavor.
- Herbs – Basil, dill, parsley and other fresh herbs provide taste.
Tips for Canning Green Beans and Carrots
Follow these tips for delicious canned green bean and carrot mixes every time:
- Make sure green beans are young and tender. Older beans can be stringy.
- Add baby carrots for perfect uniform pieces that cook evenly.
- Process jars for the time recommended based on your altitude.
- Allow 12-24 hours for jars to seal and cool before handling.
- Store jars in a cool, dark place around 50-70°F.
- Use within 1 year for best quality and safety.
- Check seals before opening. Do not consume from any jars with broken seals or spoilage.
Recommended Processing Times
Follow these USDA-approved pressure canning times for green beans and carrots:
| Jar Size | 0-1,000 ft | 1,001-3,000 ft | 3,001-6,000 ft | Above 6,000 ft |
|---|---|---|---|---|
| Pints | 25 min | 30 min | 35 min | 40 min |
| Quarts | 30 min | 35 min | 40 min | 45 min |
Testing Jar Seals
After cooling for 12-24 hours, check each jar for an airtight seal:
- Press the center of the lid. It should not flex up and down.
- Tap the lid with a spoon. It should make a clear ringing sound, not a dull thud.
- Visually inspect the seal for any breaks or gaps between the lid and rim.
If a jar fails to seal properly, refrigerate and consume the contents within a few days.
Troubleshooting Issues
Here are some common problems and solutions in canning green beans and carrots:
Cloudy Liquid
Starch released from vegetables causes cloudiness. To prevent: rinse produce, use higher processing time, and don’t can overripe produce.
Floating Vegetables
Trapped air causes floating. Prevent by packing jars tightly, releasing air bubbles, and ensuring adequate headspace.
Discoloration
Minerals in hard water can cause dull, gray results. Use soft water or add a pinch of salt or lemon juice to counteract.
Soft or Overcooked Vegetables
Overprocessing causes a soft texture. Follow recommended times precisely for your altitude to avoid.
Food Spoilage
If you detect mold, bubbles, bad smell, or other signs of spoilage do not consume the food. Botulism and other toxin risks.
Conclusion
Canning green beans and carrots together is perfectly safe when USDA guidelines are followed. The key is sticking to low-acid vegetables with a similar pH. Pressure canning and proper processing times destroy bacteria and create an airtight seal.
With so many benefits like convenience, maximizing jars, and great nutrition, mixed vegetable canning is a great way to enjoy the garden’s bounty all year. Follow the recommendations for successful results with properly sealed, long-lasting jars of canned green beans and carrots.
