I got into heat treating frozen boilies for a bit, straight into a bucket from the freezer, tip a couple of cups of recently boiled water on them and some hydro liquids and give em a good shake, as they defrost they soak in the liquids leaving you with a nice soft washed out looking bait full of sexy liquids, I found these could help with getting quicker bites,
Haven't bothered since switching to shelf life though, maybe I should still 🤔
