Honeyfin

It sits in the top group of pre-hardmode recovery items alongside the restoration potion and eggnog. All three return the same health per second of potion sickness, so choosing between them is really about pacing. This is the one that gives you the most in a single use and then keeps you waiting longest before the next, which is the wrong trade in a fight where you need the bar full immediately and the right one when you are exploring.

Outside of an Angler quest catch, this is the only thing you can pull out of honey. That makes a bee hive in the underground jungle a single purpose fishing spot: nothing else is competing for the hook, so you are not sorting junk out of your catches.

Because nothing dilutes the catch, honey is the fastest place to build up the fish you need for seafood dinners rather than doing it a few at a time between other trips.
