For the best jam, you should use nice ripe strawberries. The more naturally sweet the fruit, the better your jam will be.

*You can macerate the strawberries and sugar overnight - a common step, but one that can be left out if you're pressed for time.

To add a sophisticated touch or if your berries are a bit bland, add a spoonful of Grand Marnier to each jar just before sealing.

1. In a strainer, wash the strawberries well under running water and drain thoroughly.
2. Hull the berries.
3. Place the whole berries in a jam pot or large saucepan; add the sugar and mix.*
4. Bring the mixture to the boil and cook for 20 minutes, stirring often with a wooden spoon so that the mixture doesn't stick.
5. After 20 minutes of cooking, test to see if the jam is ready: place a drop on a cold plate. If it sets immediately, it's cooked. If not, continue cooking over medium heat and test again after 5-10 minutes.

Finishing

1. Sterilize the jars and lids and let dry.
2. Ladle the jam into the jars, seal and invert. When cooled, turn right side up.
