Why My Purse is Green

Because I believe…

  • the fastest, most effective way to stop polluters is by pressuring them in the marketplace
  • women can be the world’s most powerful economic and environmental force if we intentionally shift our spending to the best green products and services
  • women have the power right now to solve many of our most serious environmental problems by using our green purses to make a difference
  • women must act – intentionally, collectively, and with the full force of our purse power behind us – if we hope to leave our children and grandchildren a better world.

    Make Your Own Delicious, Organic Tomato Sauce. Here's How.

      Tomato2 This post is for you if you: love the taste of vine-ripened locally grown tomatoes; worry about "store bought" tomatoes containing too much sugar, salt or other additives; want to avoid canned tomatoes or tomato sauce because the can linings might contain BPA; or just like the idea of making your own food.

    This recipe is also for you if you don't want to bother with canning. I'm a fan of freezing tomatoes because it's just so easy to do.

    What you'll need

     Tomatoes - I prefer to use mostly Roma, with a few beefsteak and heirloom tomatoes thrown in. I buy organic pretty much exclusively, though have also made sauce from tomatoes my neighbors give me when their gardens overflow (I don't have enough sun to grow my own.).

    Cutting board and sharp knife - You'll need to quarter the tomatoes and remove the pulpy seeds before you throw them into the food processor. Avoid using a wooden board, since all the tomato juice will soak into the wood and make it hard to clean. A serrated knife works well to slice through tomato skin and all the way through the tomato.

    Food processor -The food processor can chop the tomatoes into such small pieces that you won't need to remove the skins, which saves a lot of time and also ensures that you keep all the vitamins, nutrients and fiber that are in tomato skin.

    Colander and bowl - You'll need a colander to drain the tomatoes after you wash them, and then again to capture the tomato juice when you're seeding the tomatoes.

    Large stock pot - Use the pot to simmer the liquid out of the tomatoes before you freeze them.

    Spoons, Ladles - A long, stainless steel slotted spoon is best for stirring the tomatoes when they're in the pot so they don't burn. Use the ladle, a large serving spoon, or a stainless steel, long-handled measuring cup to transfer the simmered tomatoes to the freezer jars.

    Freezer jars - You can buy glass canning and freezer jars, or use glass jars you've saved from other foods and sauces. I prefer glass over plastic because chemicals from the plastic might seep into the food if it's hot when you put it in the jar. If you do use plastic, make sure your sauce is totally cool before you put it in the container. Leave 1/2 to 3/4 of an inch of space between the food and the jar lid so the food has room to expand when it freezes.

    Get Started ...

      Food 030 1) Get organic, locally grown tomatoes. I went to my local farmer's market and spent about half an hour visiting several of the farmers who grow their tomatoes organically. I finally settled for about 15 pounds of mostly Romas and Beefsteak. (You can also get your tomatoes from your own garden or from a nearby pick-your-own patch. If you only shop at a grocery store, choose the locally grown, organic tomatoes they should have in stock right now.)

    2) Gently wash. Once I was back in my kitchen, I carefully dumped all the tomatoes in the sink to wash them off. I let them drip dry in a colander as I was getting everything else ready.

    3) Prepare pots and jars. I like to have all my pots, jars and utensils ready before I need them, mostly because it saves time. So get out your cutting board, knife, and food processor if you're using one. Put the stock pot on the stove. Wash your jars in hot soapy water or run them through the dishwasher.

    4) Cut tomatoes into quarters and use your thumbs to take out the seedy pulp. I do this over a colander that's sitting on a wide, deep bowl, so I can capture the juice that drips out from the seeds and pulp. Every so often, dump the seeded quarters into the food processor.

       Food 029 5) Pulse at high speed. When the food processor is about half full, pulse at high speed. If you are making sauce, you can almost puree the tomatoes. Pulse less if you are aiming for diced tomatoes. (Notice the radio next to my cuisinart. I love listening to the radio or my favorite music when I'm putting food by!)

    6) Dump pureed tomatoes into uncovered stock pot. Turn heat to simmer, and let tomatoes cook down about an hour, stirring occasionally so they don't stick to the bottom of the pot.

    Food 033 7) Let tomatoes cool. I don't try to simmer all the juice out of tomatoes I'm freezing, since when they thaw later, I will be cooking them some more and want a little juice left in them for that. I also don't add any herbs or spices to the tomatoes I freeze; I prefer to add fresh seasonings when I'm actually going to eat the sauce.

    Food 034 8) Ladle cooled tomatoes into jars. Leave 1/2 - 3/4 of an inch between the sauce and the jar lid to give the sauce room to expand when it freezes.

    That's all there is to it.


    If you want to preserve tomatoes but don't have time to make sauce now, you'll still need to get the seeds out, but you'll also need to remove the skin. Take whole tomatoes and carefully drop them into boiling water for about 30 seconds. Then immediately plunge them into a bowl of ice water. The skins should slip off easily. Quarter and seed as in step 4, then put into freezer jars and you're done.

    How Much Does It Make?

    Fifteen pounds of tomatoes will make about 5 pints of delicious concentrated sauce.

    You'll also get a good 24 ounces of fresh tomato juice out of the deal. I usually make mine  into gazpacho.

    I keep a swiss knife handy in organic gardening. I use it too cut open fruits or vegetables and savor fresh bites.

    Pest control plays a crucial role in farming for without it, plants will die or not bear fruit.


    Thanks for the site!
    I seem to always get something new.
    I never knew there were freezer jars.

    glass jars

    You can buy glass canning and freezer jars, or use glass jars you've saved from other foods and sauces.

    Regarding jars, yes, absolutely, I reuse old jars quite a bit. Thanks for your comment.
