1 liter of milk
400g of sugar
In a saucepan, cook over medium heat the milk and sugar for 40 min to 1h. If you want a really thick jam you can go up to 3h.
In the meantime, boil 1l of water and pour in the jam jars and their lids. Let them soak for a minute in the boiling water then pour the water out and dry the jam jars.
Pour the jam in the jam jars.
In a preheated oven at 150°C/300°F bake the jam jars for 15 min.
Then, take them out and allow them to cool down upsidedown.
Comment: can be used as a spread on bread, or as a good stuffing in cakes or pies, see here for example: toffee bakewell tart.
