Instructions

Making the Blackberry Jam
Cut the lemon, squeeze the juice, and mix with blackberries and sugar in a saucepan. Bring to a boil, simmer, stirring occasionally.

Boiling and Simmering
Allow the mixture to simmer for a few minutes until it thickens. Don't forget to stir so it doesn't stick to the bottom.

Checking Consistency
Once thick and glossy, remove from the heat.

Reducing to a Purée (Optional)
Transfer to a bowl and refrigerate. If smoother texture is desired, blend using an immersion blender.

Cooling Completely
Allow the jam to cool completely. When cold, it's ready to use.
Hint: Stirring the jam occasionally while simmering is crucial to preventing it from sticking to the bottom of the pan. Also, using an immersion blender can provide a smoother texture if preferred, but ensure it's blended before completely cooling for best results.
Substitutions
- For a low-sugar diet, you can use a sugar substitute like Stevia.
- Fresh blackberries can be used instead of frozen, but may require slight adjustment to cooking time.
Variations
- Add a pinch of cinnamon or vanilla extract for a unique flavor twist.
- Combine with other berries like raspberries or strawberries for a mixed berry jam.
Equipment
- A heavy-bottomed saucepan is best to prevent sticking.
- An immersion blender is handy for a smoother texture, but a regular blender or mashing manually will also work.
Storage
- Store in airtight containers in the refrigerator for up to 2 weeks.
