Well, first of all, I believe boilies generally have enough flavour - sometimes too much in fact.
Secondly, by air-drying I prolong the their life-span, but in doing so practically all their flavour goes with the drying out process, and so by glugging these I achieve two things: (1) I rehydrate them to a degree, and, (2) I reflavour them (should I feel the need).
Eh?????
