Step 1: Prepare the Turnips

1. Peel the turnips and grate them using a food processor or a box grater.
2. Rinse the grated turnips under cold water to remove any excess bitterness.
3. Drain well and set aside.

Step 2: Cook the Base

1. In a large pot, combine the sugar and water over medium heat. Stir until the sugar dissolves completely.
2. Add the grated turnips, lemon juice, orange juice, and zest. Stir to mix.
3. Toss in the cinnamon stick, ginger (if using), and salt.

Step 3: Simmer the Jam

1. Bring the mixture to a gentle boil, then reduce the heat to low.
2. Simmer uncovered, stirring occasionally, for about 45-60 minutes or until the turnips become translucent and the mixture thickens.
3. Remove the cinnamon stick and check the consistency—if it coats the back of a spoon, it’s ready.

Step 4: Blend and Store

1. For a smoother jam, use an immersion blender to puree the mixture. If you prefer a chunky texture, leave it as is.
2. Pour the hot jam into sterilized jars, leaving about ¼ inch of space at the top.
3. Seal the jars and let them cool completely before storing in the refrigerator or processing in a water bath for longer shelf life.
