600 gr sugar
zest and juice of 1 lemon
1 kg of sliced strawberries
In order to sterilize jars put them in boiling water and ''cook'' them 10 to 15 minutes. Remove them from the water and place it upside down on a clean surface to dry.
Put the sugar, lemon zest and juice in a cooking pot. Let it simmer until the sugar has melted.
Add the strawberries and stir gently. When it boils, stir for another 5 to 10 minutes.
Remove the foam and allow to cool slightly. Fill sterilized jars and close.
