Sloe and Blackberry Hedgerow Jam

Capture the taste of autumn with this delicious Sloe and Blackberry Hedgerow Jam recipe. The sweet blackberries and sharp sloes make the perfect partners.

Updated post, originally published in 2016

I feel a bit of a fraud bring you a jam recipe as in the past I have had more jammy failures than I have successes. The elusive setting point that is talked about so freely is something that has to date eluded me completely. The one time my jam did set I think was by pure luck.

However, I now have a couple of tricks in my arsenal that makes me confident of nailing any future jam making extravaganza.

Firstly, and controversially within the hardcore jam making community, I used a jam sugar. This sugar already has pectin added and it’s an easy balance between equal amounts of fruit and sugar. You can find jam sugars in the supermarket quite easily these days, and as 1 kilo of sugar makes about 3 large jars of jam, it doesn’t work out too pricey either (I used the Tate & Lyle brand).

My second little trick is using the Thermapen digital thermometer. This British made gadget is essential for those that are into making preserves as it take away any guesswork.

How to Make Sloe and Blackberry Hedgerow Jam

Firstly you need to grab your foraging basket and head outdoors. Blackberries were top of my agenda, but I was open to anything else I could throw in my basket. I ended up with a good crop of sloes, a few damsons and a handful of elderberries.

When you get home, weigh out your fruit. Scatter it out on a tray or baking sheet and pick out any bugs and debris. I didn’t wash my fruit as I didn’t want to add any water to the mix but if you feel the need, be sure to dry it well afterwards. Get all your other supplies ready from your sterilised jars to jam jar discs and cellophane lids.

Pop the fruit in a jam pan, or a very large heavy bottomed saucepan. Weigh out the equal amount of jam sugar and tip that in too. Heat the contents over a medium hot heat until all the sugar has dissolved.

It’ll start out looking crystally and then turn soupy as the sugar dissolves and the juices flow from the fruits. When there are no sugar crystals on the back of the spoon, turn up the heat and bring to a boil.

At this point get ready with your Thermapen. Keep that mixture boiling until it reaches the magic number of 105c (220f). Happily it only takes 3 seconds to record the correct temperature, so you can dip in and out safely until you get up to temperature. Also, notice how the digital display is backlit? I can’t tell you how handy that is when peering over a vat of molten hot syrup and through a cloud of boiling steam!

At this point you can test it has reached the setting point by dabbing a small amount onto a chilled plate. Once cool, if the jam skin wrinkles when pushed with your finger, you have hit jam making nirvana.

Tips to Making Sloe and Blackberry Hedgerow Jam

The sloe stones will mostly have floated to the top of the jam, where they will look yellow against the mass of purpley black jam. You can either remove them carefully before potting up, or leave them in and pre-warn people before they dive in that it contains stones. If you leave yours in, or if you’re not entirely sure you got them all out, please do not feed this jam to children. Perhaps make a separate blackberry jam just for them.

You can also add in a small knob of butter which will clear the scum from the top of the jam. Personally, I didn’t bother as I wanted to keep mine fully dairy free. The scum doesn’t affect the taste at all and is perfectly safe to consume but it doesn’t look particularly pretty.

Carefully spoon or pour the jammy goodness into your hot, pre-sterilised jars. Top off with a jam disc and cellophane lid and secure with a rubber band. Let cool before squirreling away for the winter months.

Whilst this Sloe and Blackberry Hedgerow Jam is very sweet, it also has an amazing sharpness from the sloes. It’s like a bitter marmalade, the perfect balance of sweet and sour.

If you give it a go, do let me know what you think and which hedgerow fruit you managed to snag!

Jam Making Kit

Here’s a handy list for what you’ll need to have on hand before making jam:

• A large, preferably stainless steel, jam pan
• Kitchen scales, preferably digital for accuracy
• A jam or digital thermometer
• Jam funnel. These are often plastic, but I would invest in a stainless steel one that will last you forever
• Sterilised glass jars, jam discs and cellophane lid with rubber bands, or self or locking jars like Kilner jars.
• Jam jar lifter
• Labels to mark on the contents and date the jam was made
• Fabric jam covers if you wish to make your jars of jam extra pretty.
