Prepare raspberries:
Wash and lightly mash the raspberries in a heavy-bottom pan.
Cook the fruit:
Add water and cook on medium heat for 5–7 minutes until raspberries soften and release juice.
Add sugar and lemon:
Stir in sugar, lemon juice, and lemon zest. Mix well until sugar dissolves completely.
Thicken the jam:
Add fruit pectin and continue cooking while stirring continuously. Bring the mixture to a gentle boil.
Add mint flavor:
Stir in finely chopped mint leaves and cook for another 2–3 minutes to infuse flavor.
Check consistency:
Cook until the jam thickens and coats the back of a spoon.
Store:
Pour hot jam into sterilized jars, seal tightly, and allow it to cool completely before refrigerating.
