This Week’s Harvest: Blackberries

The Organic Prepper

We have recently moved to an area where blackberries grow wild to the extent that they are considered an invasive plant by many people. An untouched patch of blackberry bramble runs amok in the back yard and the fruit is currently a sweet daily bounty.  If you don’t have them growing in your own garden, look for them right now at your local farmer’s market. (Find a market HERE)  

Some blackberry trivia:  Ancient civilizations did not cultivate blackberries, rather they gathered them from the wild.  Folklore in the UK claims that blackberries belong to the devil after Michaelmas and thus should not be picked after Oct. 11.  Early explorers of North America found them to grow prolifically in the Southern colonies and in California.  They are a native plant on every continent except for Antarctica and Australia. Other names for blackberries include brambleberries, dewberries, and thimbleberries.

Health Benefits

Any fruit that is particularly rich in color is also particularly rich in nutrients, and the humble blackberry is no exception.

  • Blackberries are loaded with minerals, particularly potassium, phosphorus, iron, magnesium, and calcium.
  • Blackberries have one of the highest levels of antioxidants found in any fruits. Anti-oxidants improve the immune function and help lower your risk of developing cancer.
  • Blackberries are high in vitamin C, vitamin K, and folic acid.
  • The seeds of blackberries hold the key to important nutrients like omega-3 and -6 fatty acids,  as well as some protein, dietary fiber, carotenoids, ellagitannins and ellagic acid.
  • One cup of blackberries contains 62 calories, 13.8 grams of carbs, a whopping 7.6 grams of dietary fiber, and 2 grams of protein.


All parts of the blackberry plant have long been used for their medicinal properties.

  • Blackberry roots are astringent and can be used as a treatment for diarrhea.
  • The berries themselves contain high levels of salicylic acid, which gives them similar properties to aspirin, such as pain relief and fever relief.
  • The leaves can be chewed or made into a tea to treat mild inflammation of the gums or sore throats.
  • Blackberry juice is a soothing treatment for hemorrhoids.

Using Fresh Blackberries

Many of the ideas here can be used interchangeably with blackberries, boysenberries, or raspberries,  depending on your local harvest.


Gently wash your blackberries in cool water and put them in a colander to drain.  Use them immediately after washing them for the best texture.

  • Blackberries make a wonderful addition to a fruit salad, a topping for ice cream or shortcake, or as a delicious, finger-staining snack.
  • Add blackberries to iced tea or lemonade for a refreshing summer drink.  Smash them gently with a fork to release more blackberry flavor into the drink.
  • Substitute blackberries for blueberries in your favorite muffin or pancake recipe.

Blackberry Cobbler


  • 4 cups of fresh blackberries (or thawed previously frozen blackberries)
  • 1 cup of turbinado sugar, plus extra to sprinkle on top
  • 1/2 cup of butter
  • 1 cup of flour
  • 2 tsp of baking powder
  • Dash of salt
  • 1 cup of milk
  • 1 tsp of vanilla extract
  • 1/8 tsp of nutmeg


  1. Preheat the oven to 375 degrees F.
  2. Melt butter in the bottom of your cast iron frying pan.
  3. Top berries with sugar, then mash them with a potato masher.
  4. In a large mixing bowl, sift together flour, baking powder, nutmeg, and salt.
  5. Stir in the milk and vanilla.
  6. Pour this mixture into the melted butter in your frying pan and  then stir well to combine.
  7. Top the cobbler dough with berries, juice,  and sugar mixture.
  8. Bake at 375 for 45 minutes or until top is golden and a toothpick inserted into the dough comes out clean.

Top with ice cream or  fresh whipped cream.

Preserving Blackberries


To freeze fresh blackberries, wash them gently, then pat them dry. Place them on a cookie sheet in a single layer and place this in the freezer for two hours.  Store the frozen berries in large freezer bags.


Blackberries may be canned in syrup for use later in pies, cobblers or crisps.  The canned berries also make a delicious ice cream or pancake topping.

Syrup Ingredients:

  • 1cup of crushed blackberries (you can also puree them)
  • 8 cups of water
  • 2 cups of sugar

Syrup Directions

  1. Bring the water to a boil
  2. Stir in the sugar and crushed berries
  3. Continue to stir until all of the sugar is dissolved and the crushed berries are well incorporated.

This is the raw pack method for canning blackberries.  Berries are very delicate and do far better when canned using this method.


  • Blackberries
  • Lemon Juice
  • Syrup


  1. Add two tsp of lemon juice to the bottom of each sanitized jar.
  2. Place the berries into your jars, allowing 1 inch of headspace for expansion.
  3.  Cover the berries with boiling syrup.  Wipe the rim and cap your jars with snap lids and rings.
  4. Process in a pressure canner for 30 minutes, adjusting for altitude.


 Blackberry Jam


  • 8 cups of blackberries
  • 1 packet of pectin + ¼ of a package (I like to use the no-sugar-needed, but then still add sugar – just less!)
  • 4 cups of sugar (I use organic turbinado sugar)
  • 1 tbsp of lemon juice (you can use more if you want the jam to have a lemon-y flavor – up to 1/4 of a cup)


  1. Prep your blackberries by washing them.  Some people like to remove the seeds but this is a matter of personal preference.
  2. Smush your berries.  You can do this with a potato masher, food processer, blender or food mill.  Some people like to puree them and have a smoother jam and others like chunkier jam – it’s also up to personal preference.
  3. In a small bowl, use a fork to mix ¼ cup of the sugar with one packet of pectin.
  4. In a saucepan, stir the fruit, lemon juice and pectin together well.
  5. Bring the mixture to a boil over medium heat, stirring frequently.
  6. Once it is boiling, stir in the sugar and return to a boil for one minute.
  7. Test your jam…(see below!)  If isn’t the proper consistency add the other quarter packet of pectin, simmer for another minute, then retest.
  8.  Ladle the jam carefully into your awaiting sanitized jars, wipe the rim and cap your jars with snap lids and rings.
  9. Process in a water bath canner for 10 minutes, adjusting for altitude.



Jam Making Rule of Law: 

Always test your jam!!!!  


You do this by keeping a spoon in the freezer – to test, drip a bit of the hot jam into the spoon to allow it to quick cool – the consistency it reaches is the consistency your finished product will be.  At this point, I nearly always end up adding another 1/4 – 1/2 package of pectin – I use the cheaper pectin to “top it up” – return to a simmer for a couple of minutes and test again.   Omitting this step may result in a very tasty ice cream topping or waffle syrup, but not jam!

    We grew up picking wild blackberries (we called them dewberries), in TX.
    Warning to all pickers: Be VERY careful of snakes. They love the berries, too.
