Of course, there are a few key considerations to keep in mind when canning pesto. For example, you'll want to use a water bath canner to ensure that the jars are properly heated and sealed. And don't even think about skimping on the acidity, or you might end up with a jar of pesto that's more like a science experiment gone wrong.
One of the most common mistakes people make when canning pesto is not following a tested recipe. Don't be tempted to just wing it and hope for the best – trust the experts and follow a recipe that's been specifically designed for canning. Your taste buds (and your safety) will thank you.
