How to make Jam - easily! With step by step photos, recipe ingredients and costs

This example shows you how to make either Strawberry jam or Strawberry - Raspberry - Blackberry Jam - also called Triple Berry Jam (my favorite, and everyone I give a jar to, says it has become their favorite, too!) But you can use this recipe to make any type of jam; where there is a difference, I will point it out! The yield from this recipe is about 8 eight-ounce jars (which is the same as 4 pints).

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

At right is a picture I took of wild blackberries - they are plentiful in late June throughout Georgia. I usually look in rural north Georgia.

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 berries (those without syrup or added sugar); which is especially useful if you want to make some 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.

How much fruit?

Jam can ONLY be made in rather small batches - about 6 cups at a time - like the directions on the pectin say, DO NOT increase the recipes or the jam won't "set" (jell, thicken). (WHY? Alton Brown on the Food Channel says pectin can overcook easily and lose its thickening properties. It is easier and faster to get an even heat distribution in smaller batches. . It takes about 8 cups of raw, unprepared berries per batch. For triple berry jam, I use 4 cups of mushed (slightly crushed) strawberries, 1 cup of raspberries and 1 cup of blackberries. For strawberry-only jam; you’ll need 6 cups of mushed strawberries.

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, the water bath processing will sterilize them as well as the contents! If you don't have a dishwasher, you can wash the containers in hot, soapy water and rinse, then sterilize the jars by boiling them 10 minutes, and keep the jars in hot water until they are used.

NOTE: If unsterilized 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 sterilized 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!

With strawberries you must remove the hulls. With other berries, just pick off any stems and leaves.

Step 4 - Crush the fruit

Then you just mush them up a bit - not completely

crushed, but mostly. Most people seem to like large chunks of fruit but crushing them releases the natural pectin so it can thicken. You'll need about 6 cups, mushed up.

If you want seedless jam, you may need to run the crushed berries through a Foley food mill (at right). They cost about $30.

It works well for blackberries, not so well for raspberries, and no one tries to remove strawberry seeds (they're so small). I suppose you could train monkeys to pick them out, but they'd probably form a trade labor union. But I digress..

Step 5 - Measure out the sugar

Depending upon which type of jam you're making (strawberry, blackberry, raspberry, apricot, peach, grape, etc.) you will need to use a different amount of sugar, jam and pectin. The precise measurements are found in each and every box of pectin sold. For most fruit; like berries, with the low sugar pectin, you'll need 4 cups of sugar. With regular pectin, about 7 cups of sugar. Mix the dry pectin with about 1/4 cup of sugar and keep this separate from the rest of the sugar. This helps to keep the pectin from clumping up and allows it to mix better!

Step 6 - Mix the berries with the pectin and cook to a full boil

Stir the pectin into the berries 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 can not be stirred away).

Why use pectin? You may run into grandmotherly types who sniff "I never used pectin!" at you. Well, sure, and their generation took a horse and buggy to work, died of smallpox and ate canned meat and green beans that tastes like wet newspapers. Old fashioned ways are not always better nor healthier. Pectin, which occurs naturally in fruit, is what makes the jam "set" or thicken. The pectin you buy is just natural apple pectin, more concentrated. Using pectin dramatically reduces the cooking time, which helps to preserve the vitamins and flavor of the fruit, and uses much less added sugar. But, hey, if you want to stand there and stir for hours, cooking the flavor away, who am I to stop you! :) We can probably find an old foot-pedal operated drill for the dentist to use when he fixes the cavities in your teeth from the extra sugar you'll need to add, too...

Notes about pectin: I usually add about 20% more pectin (just open another pack and add a little) or else the jam is runnier than I like. With a little practice, you'll find out exactly how much pectin to get the thickness you like.

Another tip: use the lower sugar or no-sugar pectin. You can add sugar to either and it cuts the amount of sugar you need from 7 cups per batch to 4 cups or less! And it tastes even better! On the other hand; I have never had success with the No-sugar pectin without adding ANY sugar. It always turned out runny and bland. You might want to try using the low sugar or no-sugar recipe with a mixture of sugar and Splenda; sugar and white grape juice, or just white grape juice - that will cut down the sugar, but still preserve the flavor.

Is your jam too runny? Pectin enables you to turn out perfectly set jam every time. Made from natural apples, there are also low-sugar pectins that allow you to reduce the sugar you add by almost half!

Step 7 - Get the lids sterilizing

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 8 - Add the remaining sugar and bring to a boil again for 1 minute

When the berry-pectin mix has reached a full boil, add the rest of the sugar (about 4 cups of sugar per 6 cup batch of berries) and then bring it back to a boil and boil hard for 1 minute...

Step 9 - Skim any excessive foam

Foam... What is it? Just jam with a lot of air from the boiling.

But it tastes more like, well, foam, that jam, so most people remove it. It is harmless, though. Some people add 1 teaspoon of butter or margarine to the mix in step 6 to reduce foaming, but food experts debate whether that may contribute to earlier spoilage, so I usually omit it and skim.

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 1/4 to 1/2 of another package) and bring it to a boil again for 1 minute.

Notes about "set" (thickening or jell): It takes 3 ingredients for jams and jellies to set: pectin, sugar and acidity. The amount of pectin that is naturally occurring in the fruit varies from one type of fruit to another and by ripeness (counter intuitively, unripe contains more pectin). See this page for more about pectin in fruit. It takes the right balance, and sufficient amounts of each of pectin, sugar and acidity to result in a firm jam or jelly. Lastly, it takes a brief period (1 minute) of a hard boil, to provide enough heat to bring the three together. Generally speaking, if your jam doesn't firm up, you were short in pectin, sugar or acidity or didn't get a hard boil. That's ok - you can "remake' the jam; see this page!

Step 11 - Optional: Let stand for 5 minutes and stir completely.

Why? Otherwise, the fruit will often float to the top of the jar. This isn't a particular problem; you can always stir the jars later when you open them; but some people get fussy about everything being "just so", so I've included this step! Skipping this step won't affect the quality of the jam at all. I usually don't bother.

You’ll also notice that the less sugar you use, the more the fruit will float (chemists will tell you it is due to the decreased density of the solution!)

Step 12 - 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 them into the boiling water canner!

Step 13 - Process the jars in the boiling water bath

Keep the jars covered with at least 1 inch of water. Keep the water boiling. In general, boil them for 10 minutes, which is what SureJell (the makers of the pectin) recommend. 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 sterilize 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 5 minutes, and the last jars were probably in for 10. I rarely have a jar spoil, so it must work. But you don't want to process them too long, or the jam will turn dark and get runny. 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 jam and then not to process the jars to be sure they don't spoil!

Recommended process time for jams in a boiling water canner.
		Process Time at Altitudes of
Style of Pack	Jar Size	0 - 1,000 ft	1,001 - 6,000 ft	Above 6,000 ft
Hot	Half-pints or Pints	5 min	10	15

Step 14 - 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.

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.

* 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.
