Wash the blackberries and plums thoroughly under cool running water. Pat them dry.
Pit the plums and chop them into small pieces.
In a large, heavy-bottomed pot, combine the blackberries, chopped plums, sugar, lemon juice, and water.
Place the pot on medium heat and stir the mixture gently until the sugar dissolves completely.
Increase the heat slightly and bring the mixture to a gentle boil. Stir occasionally to prevent sticking or burning.
Use a potato masher or spoon to mash the fruit gently while it cooks, leaving some chunks for texture if desired.
Cook for about 30–40 minutes, stirring frequently, until the mixture thickens and reaches a jam-like consistency. To test, place a small amount of jam on a chilled plate—if it forms a gel-like surface after cooling, it's ready.
Remove the pot from heat and allow the jam to cool for about 5–10 minutes.
Carefully ladle the hot jam into sterilized jars, leaving about 1/4 inch of space at the top. Seal the jars with lids.
Allow the jars to cool completely at room temperature before storing in the refrigerator for up to 3 weeks or processing for long-term storage using a water bath canning method.
