Here’s how I do it!
At home I pick out either all my left over boilies from the freezer any odds or sods, then in the kitchen, (after they have thawed) I just give them a quick blast in a food processor, with the metal chopping blade, just like in the photo, you get a nice blend of chops with some crumb attraction. The only draw back with the frozen baits is trying to air dry them, you need to hang them in a nylon bag, (the cheaper the better) with a loose weave rather than a net style air dry bag, we use for our boilies. Obviously the shelf life boilie chops are easily stored in a bucket for example, as this will not go off.

Here's how I do it at the Lakes
Chopping up boilies on the bank, particularly the amount needed to spod out, is a right pain, breaking them up with fingers, pliers or snipping with scissors can all lead to blisters!.. Me being a lazy sod, I get my boilies in a sack or air-dry bag, take it to the lodge and get on of the lads to drive over the bait a couple times to crush it for me, its that simple!!! Just make sure the bags are zipped up, don’t try it with a plastic bag, that just splits. I use DLSpecials for this, 50-50 Tiger Nut and Pineapple coated with the same bait dips, this can be spodded or put into P.V.A. bags or mesh.
