We grow around 80% of our meat, and hover around 25-30% of our overall food needs. We probably peak at 75% in the summer and fall when lots of veg is coming in. Easy enough to grow plenty of food on 6 acres of fertile land in zone 7, but things get hard when it comes to cooking and preserving it for the off season. The rest of the family is not remotely interested self sufficient food production. My wife enjoys a hobby level of production/preservation and the kids couldn’t care less, so I mostly go it alone on many larger scale food production/cooking endeavors. Last winter, I ate homegrown stewed/frozen pears and eggs for breakfast almost every day. I do most of the cooking just so I can include home grown foods, which might otherwise become compost or artifacts for future generations in our home.
In terms of calories, good old meat and potatoes do the heavy lifting. We’ve raised beef, lamb, pork, rabbits, ducks, and a handful of other poultry. Lamb and chicken eggs have proven to be the best fit for animal protein in our system. I’ve never been willing to commit to dairy, so we buy a good bit of it. I could be happy with dairy on occasion, but it is a staple for the rest of the family. We grow a pretty standard veg garden. Pumpkins and winter squash preserve easily, and we have eaten a lot of them over the years, but even I am a bit burned out on them.
Mulberries, blueberries, and figs have probably been our best producing perennials. I can only eat so much of them though due to their high fiber and sugar content. Our chestnuts are starting to produce meaningful quantities. I have experimented with roasting them and they are okay, but this fall, I want to try using them like potatoes in soups and stews. I’ve planted a lot of pecans and walnuts that are just beginning to bear. I think they could be an excellent staple food for us, if they ever produce in large quantities.
