Quick Blackberry Jam

Quick blackberry jam is so easy that you can have homemade jam in less than 25 minutes. Seriously. That doesn’t count cooling time but those extra minutes will teach you patience, young grasshopper. Good things do come to those wait!

If you’ve ever let jam making scare you, this is the recipe you’ll want to try. First, it only makes one jar, so no huge commitment. Second, it only has three ingredients. And finally, but probably most importantly, it’s quick, easy and delicious. And P.S. It's also great in muffins. Get the muffin recipe here.

Quick Blackberry Jam

As I mention in my blackberry jam muffin post, I cannot resist berries on sale. This quick blackberry jam extends their shelf life in a most wonderful, easy way.

Ingredients - for one jar - 1 3/4 cups or 414ml
3 (6 oz or 170g) punnets large blackberries (mine were Driscoll's from Mexico)
2 cups or 400g granulated sugar
2 teaspoons fresh lemon juice
zest 1/2 lemon
1 1/2 teaspoons or 7g unsalted butter - optional

Method
In your kitchen sink, sterilize one 2-cup or 480ml jar by putting a teaspoon in it and then filling it with just boiled water. Fill its lid as well. Leave to cool while you get on with the jam. I pour the boiling water over my ladle and jar funnel too, just to make sure it’s all sterilized. Once it’s cooled enough to handle, pour the water out of the jar and lid and leave to dry.

Put the clean blackberries in a heavy bottomed pot along with the lemon zest. Mash them with a potato masher until completely pulverized, occasionally using a sharp knife to cut them off of the masher grid.

Add the sugar and lemon juice. Stir well.

Put the pot on the stove over a high heat, stirring frequently, until it comes to a rolling boil. Boil for five minutes, skimming off and discarding any scum that appears with a spoon. Do not walk away from the jam at any time.

Reduce the heat to medium high and cook at a slow boil for an additional 12-14 minutes or until the jam reduces by about one-third in volume, continuing to skim scum if it keeps coming out.

You really don’t need a thermometer for this quick jam but I like to watch the temperature rise. Supposedly for jam to set, it has to reach 220°F or 104°C. This quick jam did not but it set just fine.

Remove the pot from the stove and add the butter. Stir well till the butter has melted completely.

Using a clean ladle and funnel, transfer the quick jam to your jar. Screw the lid on tightly and turn the jar upside down. Leave to cool completely. Once cool, turn the jar upright and store in the refrigerator.

Enjoy!
