Directions:Most (not all) of the time when you are canning tomatoes you'll want to first remove the skins. Now this is an optional step. It is perfectly safe to just can them with the skins on. But the skins may be undesirable in some dishes. For the most part..... I skin them. (don't toss the skins! save them for the dehydrator, they make great tomato powder.)
Depending on the size of the tomato, blanch 4 to 6 at a time. In these pictures I am working with Roma Tomatoes. I like them for canning because they are meatier than other tomatoes. They are smaller so I can fit more in the blancher. If you have a blancher or blanching basket, that makes it easier but you can also just use a slotted spoon and a big pot of boiling water.
1- Wash tomatoes and dip in boiling water for 30-60 seconds or until you see the skins split. Start counting as soon as your tomatoes hit the water. Don't wait for the water to come back to a boil to start your count time.
2-When you remove the tomatoes, drop immediately into sink or bowl of cold water to stop the cooking.
3-Slip off skins and quarter tomatoes. The skins should just slide off in your hands.
Occasionally I'll use a knife on some stubborn spots.
If you are canning tomatoes in a water bath canner, add bottled lemon juice or citric acid to the jars. 1T per pint, 2T per quart.
Add 1 teaspoon of salt per quart to the jars, if desired.
As you skin the tomatoes slice them in halves or quarters as you prefer. I will sometimes even leave my roma tomatoes whole. Place them directly into your jars. Your jars should be warm when you are working with your tomatoes. I'll usually just have them in a sink or pan of hot water. You can also run a dishwasher rinse cycle with the jars and then leave them in the steamy dishwasher until you are ready to fill each one.
Press down on the tomatoes in the jar until spaces between them fill with juice. This will crush them slightly. Leave 1/2-inch head space.
Repeat steps until all tomatoes are skinned and chopped. You may need to let your water come back to heat in between batches in the blancher.
Remove air bubbles with a small utensil. I find an orange peeler works great for this step.
Be sure and wipe the rims of your jars clean before placing your lids on. If there are bits of food it may interfere with the seal.
Place lids on the jars and process according to Water bath or Pressure Canning instructions.
Remember how your jars were hot when you filled them? They will most likely cool when you add the tomatoes. Thus you should have the water in your canner warm/hot but not boiling hot. You don't want a drastic change in temperature. Canning jars are pretty sturdy, so they will handle some temperature change... but I'd still not risk placing cool or even room temperature jars in boiling water.
So have the canner water hot but not boiling when you fill it with the jars.
Now keep in mind these are raw packed in their own juice. You should not add water to your jars. If you add water you change the acidity and there are different processing instructions.
Also keep in mind, these tomatoes will float. It is just a fact of this method of canning. Tomatoes will end up at the top of the jars after processing with more liquid at the bottom.
It is prettier to make a tomato sauce.... but this style of whole tomatoes has it's place in many of my recipes so I always do a bunch like this. With this style you can even pull out the tomatoes in the middle of winter to put on a salad. Definitely mushier than fresh... but they still hold together well enough.
Processing directions; time and pressure requirements
Processing for a Pressure canner. Process both pints or quarts - process for 25 minutes
Be sure to adjust processing according to your altitude. For more information see this altitude adjustments page. |
