Home-canning strawberries to use later is easy with the directions below. Of course, freezing is superior to retain flavor, and canned strawberries are softer and less flavorful, but if this is the method you need to use, here it is! To can other types of berries, see this page!

Ingredients

  • Strawberries - preferably fresh, but frozen (without syrup) works, too. It takes about 3 pounds of fresh berries to make 1 quart (2 pints) of canned strawberries.
  • Sugar - About 1/2 to 3/4 cup of dry, granulated (table) sugar per quart of prepared berries. You may use other sweeteners, like honey, agave, etc. but I haven't tried them, so the results may not be as good. See this page for honey / sugar substitutions.

Equipment

  • Jar funnel ($2 at Target, other big box stores, and often grocery stores; and available online - see this page) or order it as part of the kit with the jar grabber.
  • At least 1 large pot; I prefer 16 to 20 quart Teflon lined pots for easy cleanup.
  • Large spoons and ladles
  • 1 Boiling Water Bath Canner (a huge pot to sanitize the jars after filling (about $30 to $35 at mall kitchen stores, sometimes at big box stores and grocery stores.). Note: we sell canners and supplies here, too - at excellent prices - and it helps support this web site!
  • Ball jars (Grocery stores, like Publix, Kroger, Safeway carry them, as do some big box stores - about $7 per dozen 8 ounce jars including the lids and rings)
  • Lids - thin, flat, round metal lids with a gum binder that seals them against the top of the jar. They may only be used once.
  • Rings - metal bands that secure the lids to the jars. They may be reused many times.

Optional stuff:

  • Lid lifter (has a magnet to pick the lids out of the boiling water where you sanitize them. ($2 at big box stores or it comes in the kit at left)
  • Jar grabber (to pick up the hot jars)- Big box stores and grocery stores sometimes carry them; and it is available online - see this page. It's a tremendously useful to put jars in the canner and take the hot jars out (without scalding yourself!). The kit sold below has everything you need, and at a pretty good price:

Strawberry Canning Directions

Yield: 1 quart per 3 pounds of fresh strawberries

Step 1 - Pick the berries! (or buy them already picked)

It's fun to go pick your own and you can obviously get better quality ones! See this page for strawberry facts and picking tips

At right is a picture of a typical strawberry field.

I prefer to grow my own; which is really easy - but that does take some space and time and can be challenging.

As mentioned in the Ingredients section; you may use frozen berries (those without syrup or added sugar); which is especially useful if you want to make some strawberry jam in December to give away at Christmas!

Above and at left are strawberries and blackberries that I picked at a pick-your-own farm. If you want to pick your own, here is a list and links to the pick your own farms.

Step 2 - Wash the jars and lids

Now's a good time to get the jars ready, so you won't be rushed later. The dishwasher is fine for the jars; especially if it has a "sanitize" cycle, the water bath processing will sanitize them as well as the contents! If you don't have a dishwasher with a sanitize cycle, you can wash the containers in hot, soapy water and rinse, then sanitize the jars by boiling them 10 minutes, and keep the jars in hot water until they are used.

NOTE: If unsanitized jars are used, the product should be processed for 5 more minutes. However, since this additional processing can result in a poor set (runny jam), it’s better to sanitize the jars.

Put the lids into a pan of hot, but not quite boiling water (that's what the manufacturer's recommend) for 5 minutes, and use the magnetic "lid lifter wand" to pull them out.  Leave the jars in the dishwasher on "heated dry" until you are ready to use them. Keeping them hot will prevent the jars from breaking when you fill them with the hot jam.

Step 3 -Wash and hull the fruit!

I'm sure you can figure out how to wash the fruit in plain cold water.

With strawberries you must remove the hulls. (the green leaves attached to the top of the berry)

 

Step 4 - Put the strawberries in a large pot, add sugar

Place the strawberries in a large pot and add 1/2 cup of sugar per quart of strawberries.  Gently stir the berries to coat them with the sugar. If they aren't all evenly coated, add more of the sugar (up to 3/4 cup of sugar per quart of prepared berries)

 

 

 

 

 

Step 6 - Let stand for 6 hours

Let the mixture stand in a cool (40 F to 60F) place for 6 hours.

 

Step 7 - Cook the berries

Cook the mixture at low to medium heat, slowly until the sugar dissolves and the strawberries are hot throughout!

Step 8 - Get the lids warming in hot (but not boiling) water

Lids: put the lids into a pan of hot water for at least several minutes; to soften up the gummed surface and clean the lids.

Step 9 - Fill the jars and put the lid and rings on

Fill them to within ¼-inch of the top, wipe any spilled berries off the top, seat the lid and tighten the ring around them. Then put them into the boiling water canner!

 

This is where the jar tongs come in really handy!

Step 10 - Process the jars in the boiling water bath

Keep the jars covered with at least 2 inches of water. Keep the water boiling. In general, boil them for 10 minutes,  See the chart below for altitude adjustment to processing times, if you are not in the sea level to 1,000ft above sea level range.

Note: Some people don't even boil the jars; they just ladle it hot into hot jars, put the lids and rings on and invert them, but putting the jars in the boiling water bath REALLY helps to reduce spoilage! To me, it makes little sense to put all the working into making the canned berries and then not to process the jars to be sure they don't spoil!

Hot Half-pints
or Pints
10min 15 20
Hot Quarts 15min 20 25

Step 11 - Remove and cool the jars - Done!

Lift the jars out of the water with your jar lifter tongs and let them cool without touching or bumping them in a draft-free place (usually takes overnight) You can then remove the rings if you like, but if you leave them on, at least loosen them quite a bit, so they don't rust in place due to trapped moisture. Once the jars are cool, you can check that they are sealed verifying that the lid has been sucked down. Just press in the center, gently, with your finger. If it pops up and down (often making a popping sound), it is not sealed. If you put the jar in the refrigerator right away, you can still use it. Some people replace the lid and reprocess the jar, then that's a bit iffy. If you heat the contents back up, re-jar them (with a new lid) and the full time in the canner, it's usually ok.

Once cooled, they're ready to store. I find they last up to 12 months. But after about 6 to 8 months, they get darker in color and start to get runny. They still are safe to eat, but the flavor and texture aren't as good. So eat them in the first 6 months after you prepare them!  Another trick is to keep the uncooked berries or other fruit in the freezer and make and can the jam as needed, so it's always fresh.


Summary - Cost of Making Homemade Canned Strawberries - makes 8 jars, 8 oz each**

Item Quantity Cost in 2009 Source Subtotal
fresh whole berries (strawberries) 10 cups $10.00/gallon Pick your own $12.00
Canning jars (8 oz size), includes lids and rings 8 jars $7.50/dozen

Lids alone are about $1.25 per dozen

Grocery stores, like Public, Kroger, Safeway and sometimes, Big Lots, local hardware stores and big box stores $5.00
Sweetener - see step 4 4 cups $1.75 Grocery stores, like Public, Kroger, Safeway and sometimes, Big Lots, local hardware stores and big box stores $1.75
Total $18.75 total
or about $2.34 per jar

(if you already have the jars, and just need new lids: $1.85 per jar

* pectin use varies - blackberry jam needs very little, raspberry a little more, strawberry the most.

** - This assumes you already have the pots, pans, ladles, and reusable equipment. Note that you can reuse the jars! Many products are sold in jars that will take the lids and rings for canning. For example, Classico Spaghetti sauce is in quart sized jars that work with Ball and Kerr lids and rings- some authorities do not recommend these, saying they are more prone to break, and while I have found that is true of mayonnaise jars, I have found the Classico spaghetti jars to be pretty sturdy.

FAQs - Answers to Common Questions

  • As my jars are cooling after i take them out of the canner, they sometimes make a popping or hissing noise.  Is this normal and safe?
    Yes, the lids are designed to flex and that's actually a key selling point.  You can tell if a jar hasn't sealed properly (after it has cooled completely) if the lid flexes and makes a popping sound when you press the center of the lid with your finger.  The popping sounds while it is cooling is the lid being sucked down by the vacuum that is forming inside the jar - which a normal part of the sealing process.  Hissing sounds are usually just escaping steam or hot water evaporating on hot surfaces, also normal!

  • Why should cooked jelly be made in small batches?
    If a larger quantity of juice is used, it will be necessary to boil it longer thus causing loss of flavor, darkening of jelly, and toughening of jelly. It really doesn't work. Trust me; I've tried many times!
  • Can I use frozen berries instead of fresh?
    Yep! Raspberries can be particularly hard to find fresh and are expensive! Frozen berries work just fine, and measure the same. Just be sure to get the loose, frozen whole fruit; not those that have been mushed up or frozen in a sugar syrup!
  • When I used store-bought strawberries, and didn't crush them much, I got separation of the fruit from the liquid, and floating fruit in the jars?  What happened?
    The problem is the store bough are much less solid; more airy – partially due to the varieties grown for shipping, partly due to being picked more unripe, and partly due to drying out a bit during shipping. So they are less dense than the sugar solution surrounding them.  Add to this that your didn’t crush them as much.. and you get floating! They should taste ok; just stir them up when you open them.
    So, if you must use store bought, crush them more and simmer them a few minutes longer (before adding the sugar) and that should at least reduce the floating!
  • Should jelly be boiled slowly or rapidly?
    It should be boiled rapidly since long, slow boiling destroys the pectin in the fruit juice.
  • What do I do if there's mold on my jam, jelly or preserves?
    Discard jams and jellies with mold on them. The mold could be producing a mycotoxin (poisonous substance that can make you sick). USDA and microbiologists recommend against scooping out the mold and using the remaining jam or jelly.
    See this page from the US Food Safety and Inspection Service for more information. (and this page for a pdf version)
  • Why did my jellied fruit product ferment, and what do I do?
    Jellied fruit products may ferment because of yeast growth. This can occur if the product is improperly processed and sealed, or if the sugar content is low. Fermented fruit products have a disagreeable taste. Discard them.
  • What happens if my jam or jelly doesn't gel?
    Remaking cooked runny jam or jelly instructions can be found on this page
  • Could you tell me why my JAM is thicker then the store bought?
    The natural pectin content of fresh fruit varies, so it is possible the the variety of fruit that you used has more natural pectin, making it thicker. But there's an easy answer - just add less pectin next time. You'll have to experiment to find how much pectin makes the consistency you like. Most people seem to like their jam thick, so you may to need to only use 3/4 of a pack of pectin per batch. 
  • Must I use a water bath method to make jam? Can I use my pressure canner or is it not really necessary?
    Yes, you should use a water bath method; it cuts the spoilage rate down to almost zero. There are people who don't, by just inverting the jars, but unless your are absolutely scrupulously clean, you will get spoilage, and there is still a risk of food poisoning, albeit it smaller than with other canned products. Jams only need 5 minutes in the water bath anyway, thanks to the very high sugar content combined with the acidity. 
    Either water bath or pressure method works. For making strawberry jam, the water bath is easier and much faster. You needn't buy a water bath canner, if you already have a pressure canner, since you can use your pressure canner as a water bath canner, by simply not sealing it (allowing the vents to remain open, not putting the weight on it).
  • What is the best way to de-seed berries for jam? I heard a few different ways. A food mill, a ricer, and cheese cloth.
    For large seeds (blackberries, apples, and larger) I find a Foley Food Mill works best - it's certainly faster and easier than the other methods. Raspberry and smaller seeds are a real pain. They get stuck in (and clog) or pass through a food mill. The Villaware mill has a smaller screen that works great for them! See this page for more information about both strainers.  Cheesecloth and jelly strainers are messy, take forever and you lose most of the pulp. For these, I find a metal sieve or colander (with small enough holes) and a spatula to help mush them and push the pulp through, is best. Also, heating the mushed up berries almost to boiling really helps to separate the seeds and pulp.
  • Do you have a recipe for strawberry-rhubarb jam using honey for sweetener and using pectin as a thickener?
    I haven't tried it, but it ought to be possible, as the primary sugars in honey are fructose and glucose. With a no-sugar pectin, it should work well, using the usual honey–to-sugar substitution ratios that you use elsewhere. I’d estimate, that with a no-sugar pectin, you could use 2 cups of honey per batch (of 6 cups of mashed fruit) and get a pretty good result. If anyone makes jam with honey and has any tips, write me, and I'll share them here.
