Fujis, Cortlands, and Gala are all nice crisp, firm, juicy, reddish eating apples.
Granny Smiths are great for baking. (Supposedly Fujis are good baking apples too.)
McIntosh and Delicious make good apple sauce, and probably good cider too. (I find they don't stay firm and crisp very long, which is why I don't recommend for eating or baking.)
Only wild nuts worth eating around NH are hickory nuts, and they're a lot of work. I have about a dozen American Chestnut trees (courtesy of the American Chestnut Cooperator's Foundation) that might start bearing in a couple of years if they turn out blight resistant. I think they're third generation, pure American crosses. They are NOT the Chinese hybrids that the ACF is doing.
