Strawberry Fruit preserve - Made from sun-ripened, aromatic strawberries. The Senga Sengana variety cultivated and used by Alpe Pragas is medium early ripening with medium sized, dark red fruits and was bred around 1950 by Reinhold von Sengbusch. Strawberries contain so much vitamin C that 150 g of it cover the daily requirement. They contain more vitamin C than oranges or lemons.
