Place the halved and pitted sweet cherries, granulated sugar, and lemon juice into a medium-sized pot.
02 -
Heat the mixture over medium heat, stirring occasionally, until the sugar has dissolved completely and the syrup turns a deep red, about 5 minutes if using fresh cherries or 10 minutes if using frozen.

Increase to medium heat and bring the mixture to a vigorous boil that cannot be stirred down. Continue cooking for 8–10 minutes, until the mixture thickens and reaches 105°C. Test the texture by placing a few drops on a chilled plate; if the jam runs when tilted, cook for an additional minute and retest. Once the jam holds in place, proceed to the next step.
04 -
Remove the pot from heat. Use an immersion blender, ensuring the head remains fully submerged, and blend in short bursts until large cherry pieces are broken down and the jam reaches the preferred consistency.
05 -
Transfer the hot cherry jam into sterilized jars, seal tightly, and refrigerate. Allow the jam to cool and thicken overnight for optimal texture.
