Blackberry Syrup

August 19, 2009 | By andrea | Filed in: Breakfast, Dessert, Sauce.


In Oregon, blackberry brambles grow like weeds. They’re everywhere…sprouting up in fields, bare lots, backyards, and alongside rural or not-so-rural roads. Except for the impending scratches and pricks from the thorny vines, I love picking blackberries! I love the sweet smell emanating from the warm berry bushes on a hot summer’s day, and I love how a perfectly ripe berry burst with juice when eaten. Ahhh, it’s blackberry heaven!

The other day I stopped along a country road to pick a few berries (at least that was the plan) but ended up with a bucket of them because I just couldn’t stop myself. How could I let these precious ripe berries go to waste? I couldn’t, so I kept on picking them. Once I got home, I spread the perfect berries out on a cookie sheet, covered them with a damp towel and placed them in the refrigerator, fully intending to make a cake or a pie the next day.

Well, my schedule got busy and two days passed before I had a chance to do anything with them. Since my kids had been asking for pancakes, I decided to make syrup out of the berries. And let me tell you, it’s delicious! The only thing I did differently from the recipe was to add a teaspoon or two of fresh lemon juice to the syrup while it reduced just to cut the sweetness a bit (they were very sweet berries). I didn’t do the hot-water processing for the syrup (under the instructions for canning) but I did boil the jars to sterilize them like the recipe instructs. Syrup done this way will keep for 2 weeks in the refrigerator.

Fresh Berry Syrup
-recipe from Fine Cooking Magazine 

This master recipe works well with a variety of summer berries. The thickness of the syrup will depend on the berries you use: Some are juicier, resulting in a thinner syrup, while others, like blueberries, have more pectin, yielding a thicker syrup. If you prefer to skip the canning process, you can store the covered jars in the refrigerator for up to 2 weeks; to extend the shelf life, follow the canning instructions below. Yields 1 to 2 cups.

3 cups fresh berries (such as blueberries, raspberries, strawberries, or blackberries), washed and trimmed as needed and halved if large
1-2 cups granulated sugar

Bring water to boil in a large pot fitted with a rack. Carefully, put 2 empty half-pint (8 fl. oz.) Mason jars and their lids and screw-on bands in the water and boil for 10 minutes to sterilize them. Remove the jars, lids, and bands with tongs and set on paper towels to drain.

In a medium heavy-duty saucepan, crush the berries with a potato masher. Add 1/4 cup water (if using strawberries, add 1/2 cup water). Bring to a boil over medium-high heat, reduce the heat to medium low, and simmer until the berries are very soft and juicy, about 5 minutes.

Set a fine sieve over a bowl. Pour the berry pulp into the sieve and allow the juice to drip through. Gently press the pulp with a rubber spatula to extract as much juice as possible, but don’t press so hard that you force the pulp through.

Clean the saucepan. Measure the juice and then pour it into the saucepan. For every 1/4 cup juice, add 1/4 cup sugar. Bring to a boil over medium heat, stirring to dissolve the sugar. Reduce the heat to low and simmer until the syrup is viscous but still runny, about 1 minute. Skim the foam with a spoon and pour the syrup into the sterilized jars. If you’re not canning the syrup, put the jars on a wire rack and let cool to room temperature. Screw the lids and bands on and refrigerate the syrup for up to 2 weeks. If the syrup thickens during storage, stir to loosen it before serving. Serve warm or at room temperature.

To can the syrup:
Bring water to a boil in a large pot fitted with a rack insert. Carefully put 4 empty half-cup (4 fl. oz) Mason jars (use 8 if you’re doubling the recipe) or 2 empty half-pint (8 fl. oz.) Mason jars (use 4 if you’re doubling the recipe) and their metal screw-on bands in the water and reduce the heat to a simmer; simmer until ready to use. Heat the lids in very hot water for 5 minutes to soften the flange. (Don’t boil the lids when canning, as it might damage them and compromise the seal later.)

Remove the jars and rims with tongs, emptying the water from the jars. Pour the syrup into the jars, leaving about 1/4 inch of headroom. Wipe the rims clean of any spilled syrup and affix the metal lids onto the jars with the screw bands. Turn the bands only fingertip tight; don’t close them as tight as you can, or you may compromise the seal.

Put the jars in the pot fitted with the rack insert and add enough water to cover by 2 inches. Bring to a boil over high heat, and boil briskly for 10 minutes.

Transfer the jars to a rack. Allow them to cool for 12 to 24 hours. You should hear a popping sound as the vacuum seals the lid to the jar. When the syrup is completely cool, check the seals by pressing on the lids. The lids should be taut and pulled down toward the inside of the jar. If a lid bounces when you press on it, the seal is imperfect, and you will have to repeat the canning process with a new lid, or simply refrigerate the syrup and use within two weeks. You can also remove the bands and try to pick up the jars by holding onto the rim of the lids. If the lids are tight, your seal is good.

Keep the bands in place when transporting the jars, but you do not need to store them with the bands on. Store in a cool, dark place for up to a year. Once a jar is opened, refrigerate the syrup for up to 2 weeks.

Make ahead tips:
Syrup that’s not hot-water processed will keep in the refrigerator for up to two weeks.

Lemon Blueberry Syrup: Use blueberries and add 1/2 tsp. finely grated lemon zest to the syrup while still hot.
Raspberry Mint Syrup: Use raspberries and crush three sprigs fresh mint with the berries.
Blackberry Thyme Syrup: Use blackberries and crush three sprigs fresh thyme with the berries.
Strawberry Balsamic Syrup: Use strawberries. While they syrup’s still hot, add 3/4 tsp. balsamic vinegar per 1/2 cup of syrup.

Serving suggestions:
Berry syrups are terrific on pancakes and ice cream or stirred into plain yogurt, rice pudding, and oatmeal. Or try brushing them over baked ham or a pork roast to create a sweet, fruity glaze. And for a delicious homemade soda, add one part syrup to two parts chilled seltzer water.

    My husband has been making italian sodas with the blackberry syrup I made…not as clear as the commercially produced and artificially flavored syrups, but tasty, tasty, tasty.

    Great suggestion! I’ll have to try an Italian Soda made with the syrup! Thanks!

  3. margaret says:

    Is there any way to make the blackberry syrup a little thicker and still keep flavor?

  4. andrea says:

    You could try simmering the syrup for about 30 minutes for a thicker consistency.

  5. […] cut down on the sugar (using 3/4 cup instead of 1 cup) and served them with some easy-to-make Raspberry-Strawberry Syrup instead of the chocolate sauce. The sweet-tart syrup was perfect with them. This would be a great […]
