How to Make Blueberry Butter - Easily! With Step-by-step Photos, Ingredients, Recipe and Costs

Blueberries - 5 pints (which is: 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 is the low sugar formula, using about 4.5 cups of dry, granulated (table) sugar. It is possible to make low-sugar, fruit juice-sweetened, or Splenda-sweetened blueberry butter; I'll point out the differences below.
Pectin (it's a natural product, made from apples and available at grocery stores (season - spring through late summer) and in Wal-mart, grocery stores, etc. It usually goes for about $2.00 to $2.50 per box. See here for more information about how to choose the type of pectin to use.
Jar funnel ($2 at WalMart, Target, and sometimes at grocery stores) or order it as part of the kit with the jar grabber.
Jar grabber (to pick up the hot jars)- WalMart carries it sometimes - or order it here. It's a tremendously useful to put cars 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:

At least 1 large pot; I prefer 16 to 20 quart Teflon lined pots for easy cleanup.
Large spoons and ladles
1 Canner (a huge pot to sterilize the jars after filling (about $30 to $35 at mall kitchen stores, sometimes at WalMart (seasonal item). Note: we sell canners and supplies here, too - at excellent prices - and it helps support this web site!
Ball jars (Publix, WalMart carry then - 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 ($25) - 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 boiling water where you sterilize them. ($2 at WalMart or it comes in the kit at left)

Blueberry Butter-making Directions

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

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

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 blueberries (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 blueberries (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 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 8 cups of raw, unprepared blueberries per batch. For triple berry jam, I use 4 cups of mushed (slightly crushed) blueberries, 1 cup of raspberries and 1 cup of blackberries.

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 "sterilize" cycle, 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.

Lids: put the lids into a pan of boiling 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 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.

Step 5 - Puree the berries

The easiest way to get a really smooth blueberry butter is to puree the blueberries in a blender before cooking them. Alternatively, a hand-held food blender in the hot cooked blueberries works, too, but the risk of being burned by splattered hot blueberry puree is there.

Either way, if you start with 10 pints of berries, you'll end up with about 6.5 cups of blueberry puree.

Step 6 - Measure out the sweetener

Depending upon which type of jam you're making (sugar, no-sugar, Splenda, mix of sugar and 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 Splenda 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	regular	7 cups of sugar
low sugar	low-sugar or no-sugar	4.5 cups of sugar
lower sugar	low-sugar or no-sugar	2 cups sugar and 2 cups of Splenda
no sugar	no-sugar	4 cups of Splenda
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

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.

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

Stir the pectin, lemon juice and water into the blueberries 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).

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 (about 4 cups of sugar per 6 cup batch of blueberries) and then bring it back to a boil and boil hard for 1 minute.

This is a good time to add any spices you want: Typically, people add a small amount of cinnamon and/or cloves; say 1 teaspoon of cinnamon and 1/4 teaspoon cloves.

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 them into the boiling water canner!

Step 11 - 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 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 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 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. 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 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, the 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!
