A Note About Supplies
Canning can be an economical way to store food, but you do have to purchase the supplies to get started. If you'd like to try this but aren't sure you're interested enough to invest in a canner, borrow one from a friend. Can a few things to see if you like it and if it is going to be a viable appliance for you. Then, purchase your own if you think you will can often. Canners can also be bought used—just make sure they seal properly and aren't rusted.
Mason jars can usually be found in department stores. They can be reused again and again, so you only have the initial investment unless you need more jars or yours get damaged. The bands for the lids can also be reused.
You can buy used jars. Check Ebay, Craigslist, and yard sales. The main thing to be careful of when buying used canning supplies is to check the condition of the items. You don't want rusty bands or broken or cracked jars.
Most canning experts don't recommend reusing lids (flats) because they become dented and won't have an airtight seal the second use.
Other supplies like jar lifters are very handy and make the process easier, but they aren't necessary.
The basic procedure for canning food is actually easier than you would think. The essential steps are the following:
- Prepare the food to go into the jars.
- Clean and sanitize the canning supplies.
- Add the food to the jars.
- Cook them in the canner under pressure or boil them in a water bath (high-acid foods)
- Allow the jars to cool, and you're done.
This will have some variation depending on what you are canning and your specific canner. Be sure to read the instruction manual for your canner. There are tons of variations on canning instructions. People have passed on their canning knowledge from generation to generation. Find a canning recipe that works for you and the food you are canning. Most canners come with a recipe guide also. See the step-by-step instructions below!
1. Sanitize the Supplies
Thoroughly wash the canner and all of your canning equipment. Boil the lids (flats) and the bands in a pot of water on the stove for about 10 minutes to sterilize them.
2. Prepare the Food
Wash the fruit/veggies several times to make sure they are clean. Prepare the fruit, vegetable, or whatever you are canning.
- Break the beans
- Remove stems
- Cut the fruit
3. Add the Food
At this point, the instructions will vary depending on what you are canning and what recipe you are going to follow. Some people boil the food for a few minutes before filling the jars. Other people add it cold (this is called cold packing).
Fill the jars with the food, leaving a couple of inches of space from the top. Don't pack the food too tightly or else it won't heat properly.
4. Pour in Water
Pour water into the jar up to about the same point the where the food is. An inch or inch and a half of header room is good.
5. Remove Trapped Air
Remove the trapped air by moving the food with a utensil.
6. Add Hot Water
Add about three inches of hot water to the canner. Make sure you have a rack in the bottom of the canner so the jars aren't sitting directly on the bottom.
- Check your instruction manual for your canner's specific directions
7. Place on the Lid
Put the lid on the canner and seal the lid, making sure it is secure.
8. Seal With the Band
Screw the bands on the jars to seal the contents inside.
9. Place Jars in the Canner
Carefully place the jars in the cooker.
10. Seal the Cooker
Place the lid on the pressure cooker and make sure it seals correctly.
11. Heat the Cooker
Move the canner to the stove and put it on high heat (or whatever your recipe calls for).
12. Wait for Steam
Let it cook until steam starts escaping from the valve in a continuous stream for about 10 minutes. Then, add the weights that add pressure to the canner by trapping in the steam from the valve. When the weights (jiggers) start rattling, you let it cook for the specified amount of time.
13. Let It Work
When it's done, turn off the heat, remove the cooker from the eye, and let it cool down and completely vent before touching it (about 45 minutes). Carefully remove the weights and let any more steam escape for another 10 minutes. Open the lid away from you.
14. Lift the Jars
Lift the jars out of the cooker and sit them in a safe place to cool for about 8-10 hours.
15. You're Done!
Check the lids to make sure the jars have sealed properly. Your jars of home canned food are ready to go!
