How To Blanch Tomatoes For Canning

Blanching Tomatoes for Canning: A Step-by-Step Guide

Tomatoes are a versatile and delicious fruit that can be enjoyed in a variety of dishes. If you have an abundance of fresh tomatoes and want to preserve them for later use, canning is a great option. One important step in the canning process is blanching the tomatoes. This helps to remove the skin and prepare the tomatoes for canning. Here’s a step-by-step guide on how to blanch tomatoes for canning:

Step 1: Prepare the Tomatoes

Start by selecting ripe, firm tomatoes for blanching. Wash the tomatoes thoroughly to remove any dirt or debris. Remove the stems and core the tomatoes by cutting out the tough part around the stem with a small knife.

Step 2: Score the Tomatoes

Using a sharp knife, carefully score a small “X” on the bottom of each tomato. This will help the skin to peel off more easily during the blanching process.

Step 3: Boil Water

Fill a large pot with water and bring it to a rolling boil. You’ll need enough water to fully submerge the tomatoes.

Step 4: Prepare an Ice Bath

While the water is heating up, fill a large bowl with ice water. This will be used to quickly cool the tomatoes after blanching to stop the cooking process.

Step 5: Blanch the Tomatoes

Once the water is boiling, carefully place the scored tomatoes into the pot using a slotted spoon. Leave the tomatoes in the boiling water for about 30-60 seconds. You’ll notice the skin starting to peel back at the “X” mark.

Step 6: Cool the Tomatoes

After blanching, immediately transfer the tomatoes to the ice water bath using the slotted spoon. Leave them in the ice water for 3-5 minutes to halt the cooking process and cool them down.

Step 7: Peel the Tomatoes

Once the tomatoes are cool, remove them from the ice water. The skin should now peel off easily starting from the “X” mark. Use your fingers or a small knife to gently peel away the skin from each tomato.

Step 8: Prepare for Canning

Once the tomatoes are peeled, they are ready to be used for canning. You can pack them into sterilized jars, add any desired seasonings or acids, and process them in a water bath canner according to canning guidelines.

Blanching tomatoes for canning is a simple yet essential step in the preservation process. By following these steps, you can ensure that your canned tomatoes will be of high quality and ready to use in your favorite recipes throughout the year.
