Method #1: Fermenting Tomatoes (Preserve Tomatoes)
If you have extra fresh tomatoes, don’t worry! There’s an easy and healthy way to prevent them from going to waste. By combining tomatoes with salt and water, you can promote the growth of beneficial bacteria. The fermentation process enhances the flavor of the tomatoes, making them delicious and savory. You can enjoy these fermented tomatoes in salads, sandwiches, pasta, or even add them to sauces for an extra burst of flavor.

Items that will be needed:
- 2 cups fresh cherry tomatoes
- 2 cups filtered water
- 1 teaspoon salt
- 2-3 garlic cloves (optional, to taste)
- 1 teaspoon allspice (pepper, mustard seeds, or dill – optional)
- A clean glass jar (quart size works well)
- A lid
Instruction:
Dissolve 1 teaspoon of salt in 2 cups of filtered water. Mix well to dissolve. This will make the brine.
Add the tomatoes, garlic, and spices to the jar. Leave about 1-2 inches of headspace. Seal the jar.
Pour the brine over the tomatoes so that they are completely submerged. Weight them down with a small glass weight or a clean cabbage leaf to keep them submerged. Cover the jar with a lid. Leave it at room temperature, out of direct sunlight. Wait and taste. Ferment for 4 to 7 days. The longer they sit, the tangier they will become. Once you have the flavor, transfer the jar to the refrigerator. The fermented tomatoes will keep for several weeks.

Fermented tomatoes keep for a long time in the refrigerator. They are great for all kinds of dishes. They are used for salads, sauces, and pizza bases. Preserve the tomatoes before they spoil. This method of preserving is super easy and doesn’t require any fancy equipment or special skills — let me know if you try it! You’ll love how it makes these tomatoes taste.
Tips for the recipe: (Fermenting Tomatoes)
- Use ripe tomatoes –
- Sea salt, Himalayan, or kosher salt works best, meaning non-iodized salt.
- Use filtered or boiled, cold water.
- Submerge the tomatoes – always weigh them so they stay under the salt water. Exposure to air can cause spoilage.
- Start tasting after 3 days.
- Add herbs and spices – Fresh basil, dill, thyme, or chili flakes give your tomatoes a unique flavor.
- A little foam or cloudiness is normal, but a faint mold or rotten smell means you should discard and start over.
- Store in the refrigerator – Once they taste just right, refrigerate them to slow down fermentation and keep them crunchy longer.
Method #2: Freezing Pureed Tomatoes
Freezing a batch of fresh tomatoes into a puree is one of the simplest ways to preserve them for later. Whether you’re harvesting from your garden or picking up a big bunch at the farmers market, you can enjoy the flavor of summer tomatoes year-round. Here’s a simple recipe for freezing pureed tomatoes so you can enjoy them year-round:
Items that will be needed:
Instruction:
- Wash the tomatoes thoroughly and cut them into pieces.
- Place the chopped tomatoes in a blender and blend until smooth.
- (Optional) If you prefer a thick puree, simmer the blended tomatoes in a large pot for 15-20 minutes until some of the water evaporates.
- Add salt to the puree and allow it to cool completely to room temperature.
- Pour the cooled mixture into a freezer-safe jar or bag, leaving some space at the top to allow for expansion when frozen.
- Label the container with the date and contents, then place it in the freezer.

Keeps 6-8 months in the freezer without losing flavor.
Defrost in the refrigerator overnight or place the bag/container in cold water.
Whether making spaghetti sauce, adding to soup, or enjoying those summer tomatoes in the middle of winter, this will keep the garden-fresh flavor going all year long.
Tips for the recipe: (Freezing Pureed Tomatoes)
When blending tomatoes, avoid adding all of them at once. Instead, add the chunks one at a time for a smoother puree.
After refrigerating overnight, be sure to skim off the thin layer of liquid that has settled at the bottom of the jar. This step helps keep your puree thicker and more suitable for cooking later.
When storing the puree in freezer bags, leave some space at the top and lay the bags flat in the freezer. If needed, place the bags on a cookie sheet to keep them evenly spaced while freezing. This approach makes storage easier and allows for quicker thawing.
Method #3: Canning Cherry Tomatoes
Don’t forget to can cherry tomatoes even in the winter so that you can enjoy this summer flavor all year round. No matter how many tomatoes you have, you can process them in any amount. After a quick canning session, you’ll have tomatoes ready to use in a variety of dishes, such as pasta sauces, soups, or even as a flavorful topping for salads.

Items That Will be Needed:
1 kg Cherry tomatoes
Salt 1 tsp
Lemon juice 2 tsps. or citric acid ½ tsp
Fresh herbs (such as basil or thyme)
Boiling water
Instruction:
Prepare jars, lids, and bands by washing them in hot, soapy water.
Boil the jars for 10 minutes or wash them thoroughly in a hot dishwasher cycle. Keep the jars warm until they are full.
Place the cherry tomatoes in a large bowl and pour boiling water over them. Let them sit for 1-2 minutes, then drain. Now peel the tomatoes.
Place the tomatoes in the hot jars, leaving ½ inch (1.25 cm) of headspace.
Add 1 teaspoon salt if desired.
Add 2 tablespoons of bottled lemon juice or ½ teaspoon citric acid.
Now you can add a sprig of fresh herbs if desired.
Now carefully pour the boiling water over the tomatoes so that they are completely submerged.
Remove air bubbles from non-metallic containers.
To seal the jars, first clean the edges.
Place the lids on and tighten the screw to a fingertip.
Place jars in a large canner or deep pot with a rack.
Cover jars with at least 1-2 inches of boiling water.
Process:
Pints → 40 minutes
Quarts → 45 minutes
(Adjust height if necessary.)
Cool and store carefully. Remove jars and place them on a towel.
Let sit undisturbed for 12-24 hours.
Check seal: Lid should not move up and down when pressed.
Store in a cool, dark place for 12-18 months.

🌿 Tips for Canning Cherry Tomatoes
- Fresh lemons vary in acidity, so bottled lemon juice ensures safe pH levels.
- Soft or overripe tomatoes can affect texture and spoil faster.
- Skins are safe to leave on but may peel off after canning. If you want a smoother texture, blanch and peel.
- Lightly press tomatoes down when filling jars to reduce air gaps, but don’t crush them.
- Leave ½ inch at the top to allow for expansion and a proper seal.
- Slide a non-metallic spatula around the inside of the jar to release trapped air before sealing.
- Too many herbs may overpower the tomatoes. A small sprig of basil or thyme per jar is plenty.
- It adds flavor but is not required for safe canning.
- Processing times increase if you live above 1,000 feet. (Would you like me to give you the altitude chart?)
- Write the date on each jar. Use within 12–18 months for best flavor.
