Frozen Heirloom Tomatoes: German Pink, Brandywine, Orange Blossom, Green Zebra & Russian Black
Is it me, or has summer flown by a little too quickly this year? Hard to believe that Labor Day has come and gone, and there are only 2 1/2 more weeks of summer remaining. It’s been a busy season. This is good, of course, but between professional work and other obligations, I’m finding it difficult to keep up with seasonal tasks on the home front. Last year, I managed to put up a great deal of garden-fresh produce. This season, I’m in a crunch and find myself freezing more fruits and vegetables, in order to preserve them quickly and move onto other tasks …
Wheel of Wonder: Heirlooms in Various Shapes & Colors
I love cooking with fresh tomatoes and, although the killing frost is but a month away, thanks to my freezer I will be enjoying homemade tomato sauce and the flavor of fresh tomatoes in all of my cooked recipes, all winter long. Freezing raw, heirloom tomatoes is one of the quickest and simplest ways to preserve the colors and flavors of summertime. Find your garden producing more tomatoes than you have time to eat or can? Tomatoes can be frozen cooked or raw, skin on or skin off, whole, cut into sections, pureed or juiced. I preserve tomatoes in a variety of ways, but when I’m very busy —and who isn’t?— I simply freeze tomatoes without blanching or skinning. Later, I pull the tomatoes out and then blanch them (you can remove the skin just as easily after freezing and blanching) and can them, or thaw them and use as-is in my cooking throughout the winter months (freezing does destroy the firm texture, so don’t substitute frozen tomatoes for fresh in uncooked recipes). Follow the simple steps below to freeze raw tomatoes whole, and then process or add to cooked-recipes later. This method works so beautifully, I find myself wondering… Can I find a way to zip-lock and freeze a little more summertime?
Select Only the Highest-Quality Tomatoes for Freezing; No Bruises, Gashes or Mold. Wash the Tomatoes and Gently Pat them Dry Before Freezing.
Freezing Whole, Raw Tomatoes with Skin On
1) Select firm, ripe fruits for freezing. Choose the same high-quality tomatoes that you would use for a fresh tomato salad. Avoid over-ripe fruits with bruises or holes and never freeze tomatoes with any sign of mold.
2) Wash and gently pat the tomatoes dry with a lint-free towel
3) Slice the top of each tomato with a shallow “X” to prevent bursting
4) Place tomatoes (“X” up) on a cookie sheet or in freezer-safe dish and freeze until solid
5) Remove the tomatoes from the freezer. Label and date large sized zip-lock bags (a quart sized baggie fits about 3 heirloom tomatoes). Slip the frozen tomatoes into zip-lock bags according to how you will use them: measuring by weight works well if you will be using them for sauce, or you can just fill each bag and measure later. Press out extra air and zip securely closed.
6) Return bagged tomatoes to the freezer and use within 8 months for best flavor. Try them thawed and used in sauces, stews, soups, juices and pastes. You can also blanch the still frozen tomatoes and remove skins. Use the thawed tomatoes in all cooked recipes as you would fresh tomatoes, but don’t substitute thawed, frozen tomatoes for fresh tomatoes in recipes, as the texture is ruined by freezing. See steps below for blanching and removing skins from frozen tomatoes (yes, you can postpone that step and do it later)!
Prevent Explosion Upon Re-Entry by Marking the Tomatoes with a Shallow “X”. Place with “X” Facing Up and Arrange on Cookie Sheets or Freezer-Safe Pans. Stick in the Freezer Overnight.
Remove Tomatoes from Freezer and Weigh or Bag Up According to Anticipated Use. Here, Whole Tomatoes, Bagged Up & Ready for Processing Later. Be Sure to Date and Label Your Baggies and Use Produce within 8 Months for Best Flavor.
You can also puree or juice fresh tomatoes for use in recipes later. I also like to freeze fresh, homemade tomato sauce and tomato/vegetable stock. Always use containers intended for freezing and label/date ingredients. Sun-dried tomatoes are another low-labor way to preserve these heirloom treasures.

Addendum: Yes, You Can Remove Skins After Freezing Tomatoes!
This frozen, whole tomato was blanched in boiling water for about one minute. You can see the loosened skin. As soon as the skin is loose, remove tomatoes from water with a straining ladle, as shown.
I’ve received a number of questions sent via email about removing the skins after freezing the tomatoes. Yes, you can easily remove the skins after freezing. You can do this when they are still frozen solid (works very well, actually, and is easier on your hands). Simply plunge the frozen tomatoes into boiling water for a minute or two, until the skins loosen, and then remove from boiling water with a straining ladle. Allow tomatoes to cool for a minute or two, then slip the skins off with your hands. They will come off very easily. Now, place tomatoes in a bowl and allow them to continue thawing in the refrigerator until you are ready to make dinner! You can now add them to your favorite recipe (use them for stews, tomato sauce, etc), or follow USDA instructions for canning (linked below).
Skin easily slips from the still-frozen, blanched tomato (see it there, all wrinkly and cleanly pulled?). Now, place the tomatoes in a bowl, in your refrigerator and continue to thaw until it’s time to make dinner! Add to your favorite cooked recipes. The texture of thawed tomatoes is too mushy for salsa or salad… But great for sauce. You can also can previously frozen tomatoes. Follow USDA guidelines (linked above) for safely canning food.
If you are going to preserve the tomatoes by canning, thaw them and then prepare them as you normally would. Take all of the same safety precautions. I can not stress how important it is to follow the steps for canning recommended by the USDA (linked here). This post is intended for temporarily freezing tomatoes for thawing and re-using in cooked recipes.

Frozen Herb Cubes with Olive Oil: Photographs Copyright Michaela Medina – thegardenerseden.com
At six o’clock this morning, I was rather annoyed to be awakened by a gang of squawking bluejays. But when I rose, I discovered a beautiful rainbow on the western horizon. Suddenly, I found myself feeling more than grateful for the wake-up call from the noisy, blue boys in my ‘hood. The rain has ended for now, and the morning sun is warm on the terrace, where I have set up my office for the day. But before I start work on plant lists for a garden design I’m working on, I have a neat garden project to share with you. Inclement weather kept me indoors early this week, providing me with a bit of free time and the opportunity to freeze fresh herb-cubes for winter. This project is simple and fun; easy as making fruit-pops and a great way to teach children about preserving food from the garden. If you also make a few juice pops at the same time —to reward the little helping hands— so much the better!
Fresh Herbs from the Garden
Begin by gathering empty ice cube trays (or egg cups or small freezer molds), zip-lock or other storage bags, and bundles of fresh herbs from the garden. Bring the herbs inside, and as you wash, dry and pick through the leaves, think about how you might like to use them over the coming months. Do you make lots of soup in winter? Set aside a few bundles of your favorite soup herbs. These can be frozen in cubes of room-temperature water, vegetable broth or chicken/beef bouillon. Do you like to fry or roast with herbs? Bundles of your favorite cooking herbs can be preserved by freezing them in vegetable oil (I like to use light olive oil for high-temp pan frying). If you like to use herb butters or herb-infused oils for bread dipping, you can freeze them in butter (softened or melted over very low heat and cooled a bit) or in extra virgin olive oil, to pull out of the freezer later and enjoy at room temperature all winter long.
Separating Fresh Herb Leaves for Simple Frozen Oil Cubes
Tear or chop the herbs into small pieces or individual leaves, depending upon how you plan to use them at a later date. Next, load ice cube trays, egg cups or other freezer molds with the clipped herbs. You can separate individual herbs into molds or you can mix them in combinations you frequently use together. I make both individual herb cubes and various combinations. I started with olive-oil cubes for pan-frying this time. Once my compartments were filled with herbs, I began filling the cubes with oil, topping each herb mold with one or two tablespoons of light (frying) olive oil. Then I made herb cups with melted butter and extra virgin olive oil. Finally I put away large quantities of herbs preserved in vegetable broth (you can use any kind of broth) and water (for herb tea and soup).

Once the molds are filled, freeze them overnight. You may wish to make a note of the herb content and oil/water measurement in each tray. Once frozen, it can be tricky to identify the herbs. I do freeze in batches and make notes to avoid confusion later. Once removed from the freezer, pop the cubes from the trays and slip them into labeled plastic bags. I write the name(s) of the herbs, the fluid measurement, and the date on my bags. Then, I store them flat in the freezer (they should remain in separate units, unless they melt – so work quickly!). Now, you can enjoy fresh herbs in your cooking all winter long, at a fraction of the market cost!

There are many ways to preserve and store your garden produce. This particular method of freezing herbs has been around for a long time —my mother and grandmother used to preserve them in this way— and it works very well. If you are interested in learning more about how to preserve your garden produce, I highly recommend the two books pictured and linked below, which I reviewed for Barnes & Noble’s Garden Variety Blog in June (click here to read the post on B&N, where you can also purchase either book). Both titles contain new & old ideas —freezing, drying, root-cellaring and more— for preserving the harvest.
