Making and canning your own saskatoon jam is so easy. And this saskatoon jam is incredible. Even if you are a fan of strawberry, triple-berry, blackberry, or whatever, and don't like fresh saskatoons, you MUST try this! Here's how to do it, in 12 simple steps and completely illustrated. You can also use this recipe to make a saskatoon spread (see step 5).

For more information about saskatoons, see Saskatoon Picking Tips

For other types (strawberry, blackberry, peach, raspberry, etc.) of jam click here, and for easy applesauce or apple butter directions, click on these links. And here are s imple directions to make saskatoon desserts: cobbler, coffee cakes / buckles and pie!

Ingredients

Saskatoons - 10 cups, or 2.25 liters, about 3.5 lbs, almost 1.75 kg) preferably fresh, but frozen (without syrup works, too)
Lemon juice - either fresh squeezed or bottled. 1/4 cup.
Water - 1/2 cup
Sugar - See step 6. My favorite approach is to use the no-sugar needed pectin, but still add about 4.5 cups of dry, granulated (table) sugar. It is possible to make low-sugar, fruit juice-sweetened, or Stevia (in a prepared form like Truvia, it measures same as sugar; if you use another form, you will need do your own conversion) - or Splenda, if you prefer, -sweetened saskatoon jam; I'll point out the differences below.
Pectin - 1 package (box usually) or if you get it in bulk, 8 Tablespoons, see the directions below for specifics - (it's a natural product, made from apples and available at grocery stores (season - spring through late summer) and local "big box" stores. It usually goes for about $2.00 to $2.50 per box. You will get best results with no-sugar needed pectin, whether you choose to add sugar or not! See here for more information about how to choose the type of pectin to use.

Equipment

Jar funnel ($5 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 .
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:
See here for related tools, equipment, supplies on Amazon
At least 1 large pot; I prefer 16 to 20 quart Nonstick ceramic coated pots for easy cleanup.
Large spoons and ladles,
1 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!
Half pint canning 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:

Foley Food Mill - not necessary; useful if you want to remove seeds (from blackberries) or make applesauce.
Lid lifter (has a magnet to pick the lids out of the almost-boiling water where you sanitize them. ($4 at big box stores or it comes in the kit at left)

Saskatoon Jam-making Directions

This example shows you how to make saskatoon jam! The yield from this recipe is about 10 eight-ounce jars (which is the same as 5 pints).

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

It's fun to go pick your own and you can obviously get better quality ones!

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

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

At left are saskatoons (in my yard, actually; they make a great hedge or landscaping bush) almost ripe! If you want to pick your own, here is a list and links to the pick your own farms.

Step 2 - How much fruit?

Jam can ONLY be made in rather small batches - about 6 cups of prepared berries at a time - like the directions on the pectin say, DO NOT increase the recipes or the jam won't "set" (jell, thicken). It takes about 9 or 10 cups of raw, unprepared saskatoons per batch.

Step 3 - 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 a canning recipe calls for 10 minutes or more of process time in the canner, then the jars do not need to be "sanitized" before filling them. But really, sanitizing them first is just good hygeine and common sense! See this page for more detail about cleaning and sanitizing jars and lids.

Put the lids into a pan of hot, but not quite boiling water (that's what the manufacturer's recommend) for 10 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.

Need lids, rings and replacement jars?

Get them all here, delivered:

Lids: put the very hot (but not quite boiling; around 180 F, steaming water is fine)
water for at least several minutes; to soften up the gummed surface and clean the lids. I just leave them in there, with the heat on very low, until I need them!

Step 4 -Wash the berries and sort!

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

Then you need to pick out and remove any bits of stems, leaves and soft or mushy berries. It is easiest to do this in a large bowl of water and gently run your hands through the berries as they float. With your fingers slightly apart, you will easily feel any soft or mushy berries get caught in your fingers.

Then just drain off the water!

Step 5 - Crush the berries

You can go wild, be a conquering Genghis Khan crushing the peasants.. watch them flee. Well, if they're not fleeing, the berries sure do manage to roll everywhere. You won't find them until the next time you clean behind your refrigerator!

Anyway, to crush them, you can either do one layer at a time in a pan or bowl, using a potato masher..

OR you can be lazy like me and use the slice mode on your food processor.

Either way, if you start with 10 cups of berries, you will end up with about 6 to 7 cups of crushed saskatoons. Don't go all anal-retentive and worry that you only had 6.2567 cups of crushed berries.... Just take your OCD meds and the jam will turn out fine!

Note: if you want to make a smooth saskatoon spread; instead of mushing or crushing the saskatoons, just run the saskatoons through a blender until you get a smooth consistency.

Step 6 - Measure out the sweetener

Depending upon which type of jam you're making (sugar, no-sugar, Stevia (but you will have to experiment with amount, each brand of Stevia is a different concentration), or Splenda, or a mix of sugar and Stevia (or Splenda) or fruit juice) you will need to use a different amount of sugar and type of pectin. The precise measurements are found in directions inside each and every box of pectin sold (every brand, Ball, Kerr, Mrs. Wages, etc. has directions inside). I don't recommend using Stevia (in a prepared form like Truvia, it measures same as sugar; if you use another form, you will need do your own conversion) - or Splenda, if you prefer, by itself - plain old sugar makes a big difference in the color and taste. Unless you're diabetic, for best results, try the low or lower sugar formula below.

Type of jam	Type of pectin to buy	Sweetener
regular	no-sugar or regular	7 cups of sugar
low sugar	no-sugar	4.5 cups of sugar
lower sugar	no-sugar	2 cups sugar and 2 cups Splenda (or about 1/3 that if you use Stevia, which is my preference)
no sugar	no-sugar	4 cups Splenda (or about 1/3 that if you use Stevia, which is my preference)
natural	no-sugar	3 cups fruit juice (grape, peach, apple or mixed)

Step 7 - Mix the dry pectin with about 1/4 cup of sugar or other sweetener

Keep this separate from the rest of the sugar. If you are not using sugar, you will just have to stir more vigorously to prevent the pectin from clumping.

Notes about pectin: I usually add about 25% - 30% more pectin (just open another pack and add a little) or else the jam is runnier than I like. With a little practice, you will find out exactly how much pectin to get the thickness you like.

For more about the types of pectin sold, see this page!

Is your jam too runny? Pectin enables you to turn out perfectly set jam every time. Made from natural apples, there are also natural no-sugar pectins that allow you to reduce the sugar you add by half or even eliminate sugar!
Get canning jars, rings, lids and pectin deliverd:

Step 8 - Mix the saskatoons with the pectin and cook to a full boil

Stir the pectin, lemon juice and water into the saskatoons and put the mix in a big pot on the stove over medium to high heat (stir often enough to prevent burning). It should take about 5 to 10 minutes to get it to a full boil (the kind that cannot be stirred away).

Step 9 - Add the remaining sugar and bring to a boil

When the berry-pectin mix has reached a full boil, add the rest of the sugar (see step 6) or other sweetener, and then bring it back to a boil and boil hard for 1 minute.

Step 10 - Testing for "jell" (thickness)

I keep a metal tablespoon sitting in a glass of ice water, then take a half spoonful of the mix and let it cool to room temperature on the spoon. If it thickens up to the consistency I like, then I know the jam is ready. If not, I mix in a little more pectin (about 1/s to 1/2 of another package) and bring it to a boil again for 1 minute.

Step 10 - Fill the jars and put the lid and rings on

Fill them to within 1/4-inch of the top, wipe any spilled jam off the top, seat the lid and tighten the ring around them. Then put the filled jars into the canner!

This is where the jar tongs and lid lifter come in really handy!

Step 11 - 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 5 minutes. I say "in general" because you have to process (boil) them longer at higher altitudes than sea level, or if you use larger jars, or if you did not sanitize the jars and lids right before using them. The directions inside every box of pectin will tell you exactly. The directions on the pectin tend to be pretty conservative. Clemson University says you only need to process them for 5 minutes. I usually hedge my bets and start pulling them out after 7 minutes, and the last jars were probably in for 10. I rarely have a jar spoil, so it must work.

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 jam and then not to process the jars to be sure they don't spoil!

Step 12 - Remove and cool the jars - Done!

Lift the jars out of the water 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!

Answers to Common Questions

I'd like to make a home canned saskatoon topping to use later on pancakes, ice cream and sundaes. How do I do this?
That's easy! A strawberry topping is just saskatoon jam with a loose set or "jell". You can use the recipe on this page (above) and just use less pectin - about 3/4 of a package per batch!
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!
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 jellied fruit product?
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.
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!on the U.Ga. website. Remaking uncooked jams or jellies can be found in a CES Publication from Ohio State University.
