Peel the strawberries, then wash them, drain them well, add sugar over them, cover and leave overnight to leave syrup.
On the 2nd day we drain the syrup obtained with the help of a sieve.
Put the syrup in a saucepan, add the juice from 1/2 lemon, add the other half slices, put it on the fire to boil for 10 minutes, frothing as many times as needed.
Pour hot into bottles, close them well and then add them to a saucepan, add enough water to cover them and boil for 25 minutes,
We take them out of the hot water and wrap them in beds until they cool.
