'Washed out bait problems'...hmmmm...that reminds me.
During my time in carping, I tried many ways of producing skinned baits. One particularly successful method (can't for the life of me remember where I got the idea from) was to produce small 'bricks' (roughly 200mm x 60mm x 25mm) of boilie mix, wrap them tightly in cling film, and microwave them for varying times on each side. The timing was trial and error for differing mixes or effects, but as I recall, 25/30 seconds per side worked well, often enough.
This certainly did away with the loss of certain ingredients due to 'washing out' during boiling, though I assume the problem of denaturing by heat of certain elements was much the same.
Obviously, once cool, the resulting bricks could be cut up into cubes, or cut or broken into whatever shape grabbed you...except round of course
This did mean that you were severly limited in the distance baits could be catapulted out, but if you needed distance, a spod would get them there just the same.
What you did get was a very interesting mix, or choice, of bait types with each brick. Depending on cooking times, the outside layer would vary between a firm skin, to actual floaters, if you cooked them for long enough (especially the corners) The rest varied between set to still soft, with an interesting 'set one side, soft the other' layer, much like bread crust, towards the centre.
I caught an awful lot of fish using these baits...but the smell during the cooking process was absolutely astounding, resulting in the familiar 'me or it' scenario with the good lady. Still not sure if I made the right decision on that one...but I guess bait bricks would be **** in bed
