Instead of buying the tinned variety. Buy a bag of frozen corn. Get a plastic bag and add the flavouring rub the bag between your hands to spread this around the bag. Add the required amount of frozen sweetcorn and shake the bag well to ensure the corn gets coated with the flavouring. Seal the bag and allow to thaw. As it thaws the corn pulls the flavouring in.
I once bought a Tin of Sensas Red Sweetcorn think it was tutti frutti thinking it was just normal corn. Couldn't fail to get a bite on it. The carp and Tench went mad on my club pool for it. Never tryed it for a while now hmmmmm.
