Here’s one bonus: your oven is already hot, so if you’re making jam, you can slide the baking sheet of jars to the side and bake a batch of scones later. Efficiency! Your kitchen smells like warm sugar and clean glass. It’s oddly satisfying.
Another win? No sloshing water. No worrying about your stove top getting spotted with calcium deposits. Your burners stay clean, your floor stays dry, and you feel like a canning wizard. Magic, I tell you.
What If I Hear a Pinging Sound?
Don’t panic. That’s just the glass expanding. It’s normal. If you hear a crack, though—shut the oven off immediately. Let it cool down slowly. Opening a hot oven door too fast can shock the remaining jars. It’s like giving an anxious cat a bath—slow and steady wins.
To avoid cracks, always inspect your jars before baking. Check for tiny chips on the rim or hairline cracks. If you find one, retire that jar to a life of holding screws in the garage. It’s not worthy of canning.
