Peel and thinly slice the fresh ginger.

In a large pot, bring the sliced ginger and water to a boil over high heat.

Reduce the heat to medium-low and simmer for 45 minutes, stirring occasionally.

Strain the ginger mixture through a fine mesh sieve, pressing on the solids to extract as much liquid as possible.

Return the ginger liquid to the pot and add the sugar and lemon juice.

Stir until the sugar has completely dissolved.

Increase the heat to high and bring the mixture to a rolling boil.

Cook for 10-15 minutes, or until the jam has thickened and reached the desired consistency.

Remove from heat and let cool for 10-15 minutes.

Transfer the ginger jam to clean, sterilized jars and seal tightly.

Allow the jars to cool completely before storing in the refrigerator for up to 3 months.

Enjoy the delicious and spicy flavor of homemade ginger jam!
