Peel and de-seed pumpkin. Chop into very small pieces (less than 1cm x 1cm)
Place pumpkin pieces into a large baking tray. Sprinkle over all of the sugar and lemon juice and rind. Cover with a clean tea towel and allow to sit overnight.
Transfer everything from the baking tray to a large saucepan and add the rest of the ingredients.
Place over low heat on the stovetop and stir until any remaining sugar crystals have dissolved.
Bring to a steady simmer, increasing heat and then decreasing again if necessary. Continue to stir from time to time and simmer for about 15 minutes or until jam has set (see post above and notes below for more information about how to tell when jam has set).
Place hot jam into a sterilised jar and seal.
Notes
Storing: Once cooled, place the jar in the fridge and store for up to 4 months (unopened) or 2 months (once opened). There is the option of "canning" this jam so you can store it for longer periods on the shelf in your pantry. However, you'll need to rely on your own knowledge of canning and preserving as the process is too extensive to cover here.Nutrition: The nutrition information is an automatically generated estimate and is not guaranteed to be accurate.Jam-making tips: You'll know the jam has reached setting point when a wooden spoon dragged along the bottom of the saucepan shows the bottom of the saucepan for more than a few seconds (without the jam spreading back across the cleared area). The pumpkin will also appear to be more translucent and glossy.
