Tomo,
If it was Basmati rice then it was mine ( PJ wasn't allowed to use his wife's expensive rice )
Definitely works though ( although not for my boat yesterday ). I dropped in some ground bait and 1 min later watched the boat behind us haul up a bream.
Repeated this feat around 3 or 4 times.
Dont have the flashy bait dropper in use by Marineboy's team but the tesco carrier bag trick worked fine.
My groundbait mix was rice, mackeral, squid and some tropical fish pellets
Boat at Wick had around 30 bream ( onboard )
