love to cook and as far as I'm concerned this is really nothing more than cooking just with different ingredients.
Yes, indeed. That it is.
Unlike you, I haven't played around with taking the malt I have and changing it into something different. However, I would think there is a difference between taking base malt and toasting it one way or another and completely changing the character of the base malt you're starting with.
The character of the base malt is dependent on the type of barley used to make it and the process it goes through to become malted barley. I don't think there's a lot you can do to change that basic process once it's occurred. MO isn't going to be able to be transformed into pilsner malt no matter what you do to it. And I think the same would apply going the other way, trying to turn pilsner malt into a darker, richer base malt. I think you'll end up with a crystal-type pilsner, not MO.
Just my thoughts. I don't really know.
