Top Secret Boilies Maple Cream Now it’s getting creamy! Visually, the Maple Cream is really “old-school”. Its natural light colour, fine flours, high birdfood content and its absolutely characteristic Maple Cream flavour are reminiscent of the pioneers of carp fishing from days gone by. However, the composition of the boilies is anything but “old-school”. Fresh, enzymatically pre-digested cereal flours, Brocacell yeast extract, a generous portion of highly aromatic butter vanilla bisquit, milk protein, NHDC Sweetner and the legendary Maple Cream Flavour.
