Blackberry-Port Jam

I got the idea for this jam from Camilla of Culinary Adventures with Camilla fame. She was knee deep in olallieberry season at the time and was posting all sorts of wonderful berry recipes. Granted, I had no idea what an olallieberry was, but it looked to me like it was very similar to a blackberry.

I saved this recipe and her idea for Olallieberry-Port jam the first of June and just bided my time until blackberry season arrived.

Old port….luckily, no floaties. 🙂

I happened to have a very aged bottle of port.   In fact, the winery is no longer in business and I was very careful when taking out the cork.      It smelled OK, tasted OK, and I didn’t see any “floaties.”   “Besides,” I thought, “I am going to boil the heck out of it!”


Local blackberries.

Moving along, I combined Camilla’s idea with a recipe from my hero and the Queen of Jam, Rachel Saunders.

Blackberry-Port Jam
based on Olallieberry-Port Jam by Camilla and Blackberry Jam with Lemon-Basil by Rachel Saunders

3 1/2 lbs. fresh blackberries (about 3 quarts)
1 3/4 lbs. white cane sugar
3 oz. freshly squeezed orange juice
2/3 c. port

Combine all ingredients in a large kettle.   Using a potato masher, mash about half the berries as you stir in the sugar, juice and port.  Heat slowly, stirring, and bring to a boil.   After it reaches a bowl, stir often and boil for 15-20 minutes.   Be careful not to scorch the jam.   After 15 minutes, start checking for doneness.    You can go to Rachel’s site to see her frozen spoon method.   I just cook until “jammy.”

After it has reached the “jammy” state, skim off any foam if necessary.    Carefully pour hot jam into sterilized jars and seal with sterilized lids and bands.     “Gently tap the bottoms of the jars on the counter to release any air bubbles” (tip from Camilla).

Process in a water bath for 10-15 minutes.   Carefully remove  and let sit undisturbed until jars seal.   Just wait and you will start hearing popping sounds all afternoon.

This recipes makes about eight half-pint  jars.   (I did have to use two of my fake “vintage blue” pint jars.)

I love the shape of these jars, especially for gifts.

Love these vintage labels.

 “Put a bird on it!”

If you are a fan of Portlandia, you will get this reference.   If not, let me  simply tell you about these great Avery labels (#22808).   You too can make funky, vintage labels for your jam, jelly and canned-goods this summer.  (This label was made with Avery’s template maker.)


The elusive shrimp plant.

Abigail, your virtual flower for today is a little odd.   You may have them where you live, but I can only grow these during the summer months.    I fell in love with them in the rain forest exhibit at our local zoo and I try to grow one every summer.
