Recipe Size Alteration

💡 If you altered the ingredients above by doubling or tripling the recipe, you may also need to change the pan/dish size and adjust the cook time.

Notes

Yield and servings are estimates. A practical estimate is about 18 tablespoons tomato powder from 14 pounds of Roma tomatoes, based on common home dehydration yields.
Prep time is an estimate for washing, slicing, arranging, grinding, and jarring the tomatoes. Drying time varies by tomato thickness, humidity, and dehydrator model, so it is not included as active cook time.
Store the finished tomato powder in an airtight container in a cool, dark, dry place and use within 6 to 9 months for best quality.
Once reconstituted, refrigerate leftovers promptly and use within 3 to 4 days.

  3. what a great tip! i have hated tomatoes my whole life (im 50) but recently discovered I LOVE sun dried tomatoes. :lets-eat: I dehydrated a case last month and packed 2 jars in grapeseed oil and froze the rest in a ziplock bag.
    I’m experimenting now with other flavors like cream cheese and tomato paste topped with sundried tomatoes – YUMMY!
    Next I’m going to make tomato butter.
    I hate to think of all the beautiful tomatoes Ive past up in my life when I could of dehydrated them lol Grrrrr

  4. Hubby surprised me a couple of days ago with 15 pounds of huge, fully ripe tomatoes that he got at the farm stand for only $5 because each one had a small blemish. I have turned them into a full pint of tomato powder, and will take a sample to the woman who owns the farm stand. We get beautiful tomatoes year-round here in Florida, and it is wonderful to have this way to preserve them.

    I make a lot of soup, so it will not last an awfully long time, and I can buy large quantities as often as I wish. I even turn leftover spaghetti sauce into tomato leather and store it in vacuum packed jars or bags. I hate waste!

  5. Can someone tell me if i can dry tomatoes in an oven? I don’t own a dehydrator. They’re very expensive in my country. (The Netherlands, Europe) And herbs? Can they be done in an oven?
    Thanks for the help, in advance.
