Step-by-Step Instructions

Step 1: Prepare the Blackberries

Wash the blackberries under cold water, remove any stems or damaged berries, and drain well. Lightly mash about half of the berries, leaving the rest whole for added texture.

Step 2: Combine the Ingredients

Place the blackberries in a large saucepan with the sugar, lemon juice, and lemon zest (if using). Stir well and let the mixture rest for 10–15 minutes to release the natural juices.

Step 3: Cook the Jam

Bring the mixture to a gentle boil over medium heat, stirring frequently. Cook for 20–25 minutes until the berries soften and the jam thickens, skimming off any foam that forms.

Step 4: Test the Jam

If using pectin, add it according to the package directions. Test the jam by placing a spoonful on a chilled plate—if it wrinkles when pushed with your finger, it’s ready. If not, cook for a few more minutes and test again.

Step 5: Jar and Store

Spoon the hot jam into sterilized jars, leaving about ¼ inch of headspace. Wipe the rims clean, seal with lids, and let the jars cool completely. Refrigerate or process in a water bath for long-term storage.
