The best way of preparing creed wheat is to first of all buy the very best you can get hold of. It's dirt cheap.
Fill a saucepan with water and then put in the wheat, about a third of the saucepan. Then let it soak overnight.
Next day bring the wheat to the boil and allow it to simmer slowly until the wheat swells and just starts to split. some anglers used to like it when split right open.
Another way is to put a little wheat - not too much - into a thermos flask, fill it 3/4 full with boiling water and leave it overnight.
But the quality of the wheat will not be as good as the slow stewing method.
Covering it with boiling water and letting it cool will not do!
Creed wheat is a classic roach bait and will tend to select the better fish. Be careful not to use too much of it when feeding as it is extremely filling.
For a single grain use a 16 hook, for two grain when the roach are really having it, use a 14 hook. In the old days, anglers used to prefer using a gilt hook for wheat.
It's a great bait for roach in rivers such as the Trent or The Idle, especially in late summer and early autumn during harvest time.
