I USED to catch on this method for boris, very rewarding with what Graham favors, hemp and tares. Also with a giant grain of hemp on a size 14. (spades only for this game)
The feed needs to be trickled in, little and often. Sometimes bait-dropping a pint or so from when you first arrive at the peg.
Go easy with the tares, and take time practicing hooking the stuff, before your outing, if you've not used this method. (bought prepared tares are inferior)
I always cook my hemp with a little dark soft brown sugar, then strain off the liqueur after it's cooked and cook my tares in the same liqueur, adding a teaspoon of bicarb, just as the tares start to boil. They need to only to be just be boiling, a gentle simmer. Always cook in a much larger pot than what would seem normal, as the water fizzes when you add the bicarb.
When your tares are cooked, (no where as long as hemp), strain them off and spread them over a baking sheet or tray, never cool them in cold water, as this will wash flavour and some colour away.
A few red, dyed pieces of corn make an alternative to the tare, but don't feed the corn, keep just for the hook.
