Home canning is easy as long as you know a few basics steps that apply to almost all canning recipes. Make sure you have the right equipment and then keep these ten simple steps in mind, no matter what recipe you use.

10 Steps for Perfect Home Canning

  1. Bringing a canning kettle of water to a boil takes awhile—up to 45 minutes over high heat. Be sure to get it on the stove before you start anything else. The canner should be about half full for pint jars and two-thirds full for quart jars.

  2. Sterilize the jars and lids by setting them in boiling water for 10 minutes or running them through the "sterilize" cycle on a dishwasher.

  3. Make sure to thoroughly rinse and pat dry the produce you're canning before you start the recipe.

  4. Ladle food into sterilized jars through a wide-mouth funnel. Make sure to leave the headspace (the space between the top of the preserves and the top of the jar) specified in the recipe. If the final jar you fill isn't full, don't process it. You can cover it can keep it in the fridge instead.

  5. Run a thin-bladed knife along the inside of the jar to release any air bubbles along the sides of the jars. Wipe top edges of jars clean with a damp cloth or the jars may not seal.

  6. When you put the lids on the jars, make sure that the sealing compound around the edges of the lids touches the rims of the jars. Screw the metal rings on firmly but not tightly and don't force them. Just screw them on, so they stay in place.

  7. Lower the jars into the boiling water (180 F to 185 F for pickles). The jars should be covered by at least 1 inch of water. Add boiling water, if needed, during processing, to keep that 1-inch buffer. Cover canning kettle to return water to a boil. Process for the time specified in the recipe.

  8. Lift jars out with tongs. Have a hot pad on your other hand, just in case you need to grab something—set jars on a flat work surface. Pat dry, if you want. Don't tighten the rings, just let them sit until completely cool to room temperature. You may hear a slight "ping" from the jars as they seal. This is a good thing.

  9. Push down in the center of each jar. If it stays down, excellent. The jar is sealed. If it pops up the jar isn't sealed. Store unsealed jars in the fridge and use contents sooner rather than later.

  10. Make sure to label jars with contents and canning date—store jars in a cool, dark place and use within a year.
