Honey the bee creates expires quickly. (even in a fridge.)
You can actually (attach) the honey to a fishing rod and remove at anytime. This will prevent the honey from ever expiring! Good way to store it as fishing rods are so cheap to make!
The honey is a must for fishing. It can be used for salmon, just like leech blood. I used it as bait for an hour and noticed that fish bite more frequently. In a pool with coel and salmon, I noticed that the salmon bit more frequently than the coels while using honey as bait.
