Give my garden 10 years and I will hopefully have it down pat. Rotating seasonal crops, a rich soil from a well established compost system and established fruit trees. Much like my father's. Dinner will look very much like what we had growing up - hearty stews and home made pies. Having the wh*** family around, and anyone who imght be extended family because they need a feed. The door will always be welcome and there will be plenty to go around because we will plant for excess.
And, as happens now, the excess will be shared - trays of eggs or bags of tomatoes given to my neighbours. We won't have tomato soup from a can, we will make it to use up what we have.
I will tell you a curious thing - when you do have seasonal veg, and a lot of, everyone cooks the same thing, but in their own way, so there is a community built around competitive cooking. Whose soup is best? Who bakes the best mulberry pie? Who was cleverest in using the off-cuts? A convergence on what is in season that creates a community or strengthens a family.
In 2020 I hope to be impressing my father with a desert made of the fruit of the sapote tree. I've not tried to cook with them before, so it will be some kind of experimental dessert, but since they are the "chocolate pudding fruit" I'm pretty confident it will be delicious!
