Nashbait Flake, developed by Kevin Nash, is made from whole boilies that are cooked and then processed to create two components: irregular sliced fragments and a finely ground crumb. This combination not only enhances the bait's flavor and scent but also generates a cloud in the water, making it an essential additive for grubbing mixes, boat feeding, and spod mixes, effectively keeping carp feeding actively over various substrates like weed and silt.
