Are you talking about a groundbait called TNT Porridge - if so I havent used it myself but it is marketted by Steve Gregory one of the best match carp anglers in the UK. If this guy uses it it has to be good
me it was on old lancaster my granddad said to try it so i did and it worked it breaks down pretty slow so theres a thick bed of bait at the bottom also tryed it on my local res mixed with brown crumb. this may sound missleading but court nowt on the canal but i did on the res but my grandad court on a private stretch on six arches. also i just added water to make a firm mix it sticks all over mind
I soaked mine overnight and in the morning it looked like the dog had been bad
It was used on a stillwater,and nothing more than brown sugar put in it when soaking previously.Red maggot fished over the top,and on occasion a small red worm.
