Preserving your harvest is a great way to enjoy your homegrown fruits and vegetables long after the growing season ends. However, it’s easy to make mistakes that can affect the quality and safety of your preserved foods.
Knowing which common errors to avoid can help ensure your harvest stays fresh and safe for consumption. By understanding these pitfalls, you can protect your effort and enjoy your produce with confidence.
Using untested or homemade canning recipes
You should avoid using untested or homemade canning recipes. These recipes might not be safe because they haven’t been scientifically tested.
Using unproven recipes increases the risk of food spoilage or harmful bacteria growth. Always follow trusted, tested recipes to keep your harvest safe. For more details, check out advice on avoiding common canning mistakes.
Adding extra starch or flour to preserve recipes
You might think adding starch or flour will thicken your preserves, but it can actually cause problems. These thickeners slow heat penetration, which means your jars might not reach the proper temperature.
This increases the risk of underprocessing, potentially allowing harmful bacteria to survive. Stick to tested recipes without extra thickeners to keep your harvest safe and tasty. Learn more about this at Mississippi State University’s guide on 10 home canning mistakes to avoid.
Not processing jars at the correct temperature
You need to make sure your jars reach the right temperature during processing. If the temperature is too low, harmful bacteria might survive.
Using an inaccurate pressure canner gauge can cause this problem. Test your gauge every year to keep it reliable.

Storing preserved foods above 70°F for too long
If you store preserved foods above 70°F, their quality can decline faster. Heat encourages the growth of bacteria and mold even in sealed jars.
Your food’s texture, flavor, and color may change, making it less enjoyable. Try to keep your preserved harvest in a cool, dark place to extend its shelf life.

Using cold jars instead of hot jars in canners
You should always warm your jars before placing them in a canner. Using cold jars in a hot canner can cause the glass to crack or break during processing.
Warm jars help maintain an even temperature, reducing the risk of jar damage and ensuring your food preserves properly. Avoiding this mistake protects both your harvest and your equipment.

Running hot canners under cold water to cool
You might think cooling a hot canner quickly with cold water saves time. However, this sudden temperature change can crack your jars and ruin your preserves.
Instead, let the canner cool down gradually on its own. This gentle approach helps protect your jars and keeps your harvest safe. For more tips, check out common canning mistakes to avoid.
Changing ingredient amounts without adjusting processing time
When you change the amount of ingredients in a canning recipe, you also need to adjust the processing time. If you add more or less, the heat may not reach the right temperature inside the jar.
This can lead to underprocessing, which puts your preserved food at risk. Always follow tested recipes or find reliable adjustments before altering ingredients. For more details, see common canning mistakes to avoid.
Preserving butter by canning instead of freezing
Canning butter can be tricky because fats protect bacteria from heat during processing. This means you might not kill all harmful bacteria when you can it.
Freezing butter is a safer choice for long-term storage. It keeps your butter fresh without risking spoilage or health issues. For more details on this, check out advice on canning mistakes to avoid.
Ignoring small bruises or lesions on produce
You might think small bruises or lesions on your fruits and vegetables are harmless. However, these damaged spots can quickly lead to spoilage during preserving.
It’s best to carefully inspect and remove any bruised or damaged areas. This helps protect your entire batch and keeps your harvest fresh longer. Avoiding these common mistakes improves your preserving success, as explained in avoiding common canning mistakes.
Failing to discard moldy or diseased food
You should always remove moldy or diseased produce before preserving. Keeping bad food can spoil your entire batch.
Even small signs of mold mean the food is unsafe to eat or store. It’s best to discard these items completely.
Trimming minor bruises is okay, but mold and disease can spread unseen. Don’t take risks with your harvest’s safety.
