Water Bath Using 2 Tbsp Lemon Juice for Heirloom Tomatoes

Asked January 24, 2020, 2:42 PM EST

What a great resource here! Thank you! I do have a question about canning tomato products. With all the newer & heirloom tomato varieties out there now that could be less acid varieties ( I do heirloom for 99% of mine) is it still safe to water bath using 2 tbsp of bottled lemon juice? Thx in advance!

Yes, tomatoes need to be acidified for this exact reason - because the acidity of tomatoes is borderline for safely water bath canning. The recommendation is 2 Tbsp bottled lemon juice per quart, or 1 Tbsp per pint. Then you are assured a proper acidity for water bath canning.
Thank you for reaching out!
