In a large pan, cook the nectarine with the sugar until the sugar has fully dissolved on a medium heat

Cook the mixture for 15 minutes then add the lemon and grated ginger

Remove the excess foam

Cook for another 20 minutes. You can mash the fruits slightly if you prefer a smoother jam or leave as it is if you like bigger bits of fruits

Test if your jam has set by pouring a small amount of jam on a cold plate. Let it cool down, run your finger through it, if the sides crinkle, your jam is set

Sterilized two large jars, pour the jam mixture into them and let them cool down before refrigerating
