The correct pellet size is 2 or 3 mm for the method-feeder. This size will hold the cast perfectly and leave the bait easily. A dip will be useful to boost the wetting.
Pour the desired quantity of pellets into a container and pour a little soaking liquid over them.
Homogenize the liquid on the pellets and leave them to soak for a few minutes.
Pour the pellets, soaked in the soaking liquid, into a sieve.
Put water in a container and leave the pellets to soak (covering them completely with water). Leave for 1 to 5 minutes, depending on the texture you want. The longer you leave them in, the more water they'll soak up. The longer you leave them, the more water they'll soak up, and the softer and stickier they'll be, the longer they'll come off the method-feeder. I usually leave them in for a minute or so.
Drain the pellets and place them in a container. Cover and leave for a few minutes to swell.
Stir the pellets to loosen them from each other (I use a fork for this). You can add a little more soaking liquid if you want to boost them, or add a little more oil to the water column in the station.
The pellets are ready for fishing. Prepared in this way, they will easily hold together and on the method-feeder (the mould is easily used), but they will loosen well from the method and keep a pellet shape while remaining a little hard in the water.
I use wet pellets like this when I want a bait that feeds the fish on the spot. Unlike flour (groundbait), pellets are more nourishing and keep the fish active on the spot. On the other hand, because they are less "volatile", they take longer to attract carp to the spot and to the method-feeder.
