I've long been of the opinion that to be happy cooking on boats it is needful to take a step back and think before you try to recreate the sort of kitchen and cooking gear you are accustomed to on land. Which, is not so hard when you consider that most of the gear in your land bound kitchen never ever actually gets used if you are like most people. The trick is not to change the way you cook but to simply take note of how you really cook and the tools you use.
All of us who cook tend to use the same tools all the time and the rest just gets stuck back in a cabinet and waits till the urge to pull them out and do something with them... Face it, when was the last time you used that set of jello molds?
On "So It Goes" I use three pans and a pressure cooker that get constant use and a corner of my galley storage has some pans that never get used so why are they there? The fact is, If I had a huge kitchen with all the room in the world I'd still use those three pans because that is what works.
The point it... You don't really have to change how you cook or what you use simply work out what you don't use and give them to the goodwill or some such and they might actually wind up with someone who will use them (well maybe not those Christmas Jello molds...) but you get the idea!
