LBJ preserves are made in small batches, and cooked for a shorter time compared to generic brands.The flavour is honest and unadulterated; it is fruit-driven, rather than sugar-driven. When tasting LBJ preserves you will always taste the fruit first followed by the sugar and a special complimentary flavour. We use natural, unrefined sugars and no commercial pectins. LBJ preserves contain no more than 4 ingredients and are dairy free & vegan.
