That can be tricky, but there are great cookbooks out there that cover that. One is:
You also have to be WILLING to eat or preserve what's available when it IS available, and that's yet another skill set to learn along the way.
My Mom grew up dirt-poor. She will never, willingly, eat another stewed tomato in her life, LOL! Though , she's a sly one at raiding my garden in season! I've never seen my Mom 'grow' anything, other than her daughters. Mom taught us to sew, about art and theater and religion. She's the complete opposite of her Mother, my Grandma Anita, who taught me a LOT about growing food, cooking, butchering, making sausage, raising chickens, buying direct from farms, (in inner-city Milwaukee, no less!) so I more than make up for that and Mom loves that aspect of our lives. "Being with you is so much like being with Ma," she always tells me when she's out here at the farm, helping me weed the garden and stealing vegetables, LOL! :)
