Note: start 24 hours before
Clean the strawberries. Dip each strawberry in the rum and place on a large plate. Sprinkle with half of the sugar and refrigerate for 24 hours.
A day later, make the syrup. Boil the water with the remaining sugar, add the strawberries and boil three more times. Carefully skim off the foam repeatedly. Continue to boil gently over low heat until the strawberries no longer taste sour and the jelly is covered with a skin.
Cool before bottling. For this purpose, it is best to fill into faience or earthenware dishes.
Note: Offer the skimmed foam to the tea as well.
