My wife's Dad did about the same thing in Connecticut. He collected and burned more soft wood making maple syrup than he did heating the house.I burn about 7-10 full cords of wood cooking every year. Cooking maple syrup, that is... I suppose that's not what we're talking about though.
I cook pretty often on my Morso during the winter. Certainly not exclusively, but when it's hot and I'm cooking, we usually work together.
On the topic of wood cook stoves in summer heat, though, I learned a great term for softwood: "biscuit wood". The name coming from when wood was used for cooking, and the cook needed to heat the oven to make biscuits but didn't want a lasting fire. Softwood or biscuit wood was the firewood of choice. That's pretty much what I refer to softwood as now. When I remember anyways.
The "softwood" that I collect today is for campfires that people burn at the parks -- cottonwood, willow, soft maple, linden, etc. Unfortunately, they use that for cooking also and ignore my oak, hickory, locust, hard maple, ash, and so on.
