I've used strawberry Coolaid and other sweet smelling drinks/liquids on them. I've caught some fish that way, but I'm not sure I haven't caught just as many without the soaking. Just cut 'em up in one inch chunks and put them on the hook. I've even sprayed them with garlic scent, WD-40, etc. and caught fish. I'm not sure the added liquid/spray scent does any good but it makes me feel better.
