My parents used to do that when I was growing up and here and there through the years I also grew "some" of what I enjoyed in winter, but I no longer have a garden, so I buy most things unless someone had an over abundance in the summer and shared. It's always so much better when it is home grown and stashed for winter.
Your snow and your soup look fun and delish.
My mother and her cousin grew and preserved a lot of foods. For many years I bought absolutely everything, but when it started to look as if I would be denied access to my money (covid con, unjabbed) I started growing my own food. A big unexpected benefit has been that I am healthier!
It's not quite free, because there is a lot work involved. But the work is outside, in the summer and for that I am grateful. I don't often has excess, but when I do, it's fun to give give give. This year I gave peaches. To everyone.
I wish you a space you can grow food in, if only a tiny bit.
