Mushy homemade dill pickle chips
Keeping vegetables directly on ice tends to create damage on a cellular level, leading to softness once the vegetables are processed. Next time, instead of using ice, consider a cold brine bath, with or without added vinegar, for your cucumbers and/or slices. If you have room in the fridge, you can store them there overnight. If not, put them in a non-aluminum pot, wrap it twice with bubble wrap to prevent direct contact with ice, and store the pot in a bucket or a larger pot filled with ice.
