- 3.2 kg berries, small and firm if possible, stems removed, unwashed
- juice of 2 lemons
- 2.7 kg raw unprocessed sugar
Prep: 20 minutes | Cook: 30 minutes
Put the berries and lemon juice in a preserving pan or large, heavy-based stainless steel saucepan.
Heat gently until the juices start to run, then use a potato masher to mash into the required texture, keeping some of the strawberries whole if you like. Continue cooking and stirring often until the mixture is reduced to a thick slush.
Add the sugar to the saucepan and stir continuously over a low heat until completely dissolved.
Bring the mixture to the boil and boil steadily for 15–20 minutes, stirring frequently, until the setting point is reached (105°C on a sugar thermometer).
Ladle the jam into warm, sterilised jars, then cover and seal. When cold, label, then store in a cool dark place.
Use within 1 year of making.
Once opened, store in the fridge and use within 1 month.
