Crushed sweetcorn powder is a relatively new groundbait ingredient. Sweetcorn in its natural and dyed state is very popular bait, so it makes sense to utilise this fish attractor in groundbait too. Sweetcorn based groundbaits work well for carp, bream, barbel, chub, big roach and tench. Some anglers even liquidise sweetcorn and then add it to groundbait, but this needs to be done in moderation, otherwise the feed turns very mushy.
