How to Make Tomato Paste
Ingredients
- 10 lbs fresh, ripe tomatoes (Roma or other paste tomatoes are ideal)
- 2 tablespoons bottled lemon juice per quart jar for canning safety
- 1/2 teaspoon salt per jar (or to taste)
- Optional: 1 to 2 teaspoons sugar if your tomatoes are a bit tart
Directions
- Start by washing your tomatoes really well and cut them into quarters. Remove any stems or bad spots.
- Bring a large pot of water to a boil. Quickly put the tomatoes in for about a minute to loosen the skins. Then, move them into a bowl of ice water to stop the cooking.
- Once the tomatoes are cool enough to handle, peel off their skins. You can also scoop out some of the seeds if you prefer a smoother paste.
- Crush the tomatoes by hand or run them through a food mill or blender until you get a nice, even puree.
- Pour the puree into a large heavy pot and start cooking it over medium heat. Stir it frequently so the tomatoes don’t stick or burn.
- As the tomato mixture starts to thicken, add in the salt. If your tomatoes are a bit tart, stir in 1 to 2 teaspoons of sugar.
- Keep simmering the puree until it reduces to a thick paste. This can take a long time, so be patient and keep stirring every now and then.
- Meanwhile, sterilize your quart jars by boiling them in water. Once they’re clean, add 2 tablespoons of bottled lemon juice to each jar for safe canning.
- When your tomato paste is ready, carefully ladle it into the hot jars over the lemon juice, leaving a bit of space at the top.
- Process the filled jars in a boiling water canner for about 35 minutes for quart jars to properly seal them. Let the jars cool completely before storing them in your pantry. Enjoy your homemade tomato paste!
How to Serve Tomato Paste
Tomato paste is a versatile ingredient. You can use it to enrich sauces, soups, and stews. It’s also great for making pizza or pasta sauce. Just add some herbs and spices, and you’re set! You can even mix it into marinades for meats or vegetables to give them a deeper flavor.
How to Store Tomato Paste
Store your canned tomato paste in a cool, dark place, like a pantry or cellar. Make sure to keep the jars sealed. Once opened, transfer any unused paste to the refrigerator and use it within a week. For longer storage, consider freezing the paste in small portions.
Tips to Make Tomato Paste
