Why can ketchup at home?
Canning ketchup at home has several benefits. First and foremost is taste. It allows you to preserve the flavors of fresh, ripe tomatoes when they’re in season and enjoy them throughout the year.
Homemade ketchup also gives you greater control over the ingredients. It allows you to customize the recipe to suit your tastes.
Canning also has economic benefits, as it can be more cost-effective than buying store-bought ketchup, especially if you have access to a garden or farmers’ market to buy tomatoes in bulk.
It is also a great way to reduce food waste by using excess tomatoes that might otherwise go bad. Similarly, canning your own can be better for our planet since you are reducing plastic waste and eliminating the pollution caused by shipping
Finally, home canning is a fun project where you can use your own creativity. It can also be a great way to share your homemade ketchup with family and friends or to give as a hostess or holiday gift.
What types of tomatoes are best?
Whatever tomato you have on hand will work. But, when making ketchup, the best tomatoes are meaty, low in water content, and high in natural sweetness and acidity. Here are a few types of tomatoes that are well-suited for making ketchup:
- Roma Tomatoes: They are a popular choice for making ketchup because they’re meaty, have low water content, and are naturally sweet. They also have fewer seeds than other varieties, making them easier to work with.
- San Marzano Tomatoes: San Marzano tomatoes are another excellent choice for making ketchup. They have a dense, meaty texture and a high sugar content, which makes them perfect for creating rich, flavorful ketchup.
- Heirloom Tomatoes: Heirloom tomatoes come in various shapes, sizes, and colors and can be an excellent option for making ketchup if you want to experiment with different flavors and textures. Some heirloom varieties, such as Cherokee Purple or Brandywine, have a dense, meaty texture and a rich, complex flavor that can make delicious ketchup.
Ultimately, the best type of tomato for making ketchup depends on your preference and what’s available in your area. Regardless of which variety you choose, look for ripe, flavorful tomatoes that are in season for the best results.
What you need
- Tomatoes: Fresh, ripe tomatoes are the star ingredient in ketchup. You can use any meaty tomato that is low in water content and high in natural sweetness and acidity. Roma tomatoes, San Marzano tomatoes, and heirloom tomatoes are all good options.
- Onion: Onion adds a savory depth of flavor to ketchup. Yellow onions are the most commonly used, but you could also use red or white onions.
- Garlic: Garlic adds a pungent, aromatic flavor to ketchup.
- Vinegar: Add vinegar to balance the sweetness of the tomatoes and add tanginess to the ketchup. White vinegar, apple cider vinegar, or red wine vinegar are all good options.
- Sugar: Sugar adds sweetness to the ketchup and helps balance the acidity. Depending on your preference, you can use granulated sugar, brown sugar, or honey.
- Salt: Use as a flavor enhancer for the ketchup.
- Spices: Ground cinnamon, allspice, cloves, cayenne, celery seed, and black pepper can add depth and complexity to the ketchup. Worcestershire sauce, mustard powder, and paprika are also popular additions.
How to make it
Step One
Chop the onion and mince the garlic.
Step Two
Break up cinnamon into pieces. Use a hammer or meat mallet to crush it.
Step Three
Add spices to a spice bag.
Use a reusable produce bag or make one out of a few layers of cheesecloth.
Some of the celery seeds may fall out, which is fine.
Step Four
Add ingredients to the tomato juice.
Step Five
Mix it well. Bring to a boil. Reduce heat to a low boil and cook the sauce or 30 minutes, stirring occasionally. Turn heat down to a high simmer and cook until it is thick.
Remove the spice bag after 15-30 minutes. Taste it before you remove it to see if you can taste these spices. Remove it when you like the taste.
Step Six
Use an immersion blender to puree the onions and garlic until smooth.
You can also do this with a stand blender in batches.
Step Seven
Fill the hot jars with hot ketchup with a canning funnel leaving a ½-inch headspace.
Step Eight
Remove the bubbles with a bubble tool or a plastic or wooden chopstick.
Step Nine
Wipe the rims of the jars with a damp paper towel to remove debris.
Center lid on jar. Screw bands fingertip tight.
Step Ten
Place jars in your canning pot. Be sure the water covers them by about 2 inches.
Notice we have a clean kitchen towel in the pot. We didn’t use our canning pot, just a tall pot, and added the towel to keep the jars off of the bottom of the pot.
This is convenient when small batch canning so that you don’t have to drag out your canning pot.
Get the canner water hot, and add the filled jars. Once the water is boiling, set the timer.
Once processing time is done, remove the pot from the heat, carefully open the lid, and move it partially off the top of the canning pot. Let it rest like that for 5 minutes.
Then remove the lid and allow the jars to rest another 5 to 10 minutes in the canning pot.
After resting, remove the jars onto a kitchen towel placed on your counter and let them thoroughly cool for 12-24 hours, undisturbed. You may hear the lids pinging sometime in the next hour. This is music to a canner’s ears. It is due to the reaction of the lids being sealed to the jar.
Check the seals. Press down in the middle of the lid. If it flexes up or down, the jar is not sealed and should be refrigerated and used first.
Then remove the bands. Gently pick the jar up by the lid to further check the seal. Again, if it is not sealed, use it first.
Label jars with contents and the date. Store in a cool, dark space.
Pro- Tip: When canning, choose a reputable source for your recipe. The National Center for Home Food Preservation is one and the other is the USDA Complete Guide to Canning.
All of the recipes on this site are based on one or both of these trusted sources. We just do a more thorough job showing you how to do it, step by step.
