Last Christmas, supermarkets had a special on certain vegetables, much cheaper than usual; this has happened for a few years in a row and we knew to stock up. So for about four days, we went in and bought around 10 kg of various fresh veg; we froze some, dehydrated some, and kept the rest for fresh eating. It was mostly carrots, parsnips and swede, but a few kgs each of potatoes, cabbage and Brussels sprouts too. So obviously, 10 kg a day for four days was about 40 kg in less than a week. We were in production mode for several weeks afterward, keeping the dehydrator and freezer trays going.
But here's the thing: we still have nearly all the dehydrated carrots, parsnips and swede in the cupboard. It's not that it's inconvenient to use; on the contrary, it's so easy to just tip some into a stew (and we eat plenty of stew!), curry, stir fry, whatever. And I haven't forgotten it's there either--it's just that this year I've had so much fresh veg from the garden, my dehydrated veg hasn't been needed.
In past years I've done a no-buy vegetable challenge for several months at a time, eating only veg we grew ourselves, were given/traded, or otherwise got for free. The longest we officially went without eating bought vegetables was seven months (however, I did buy some veg at the six month mark, which officially broke that challenge). This is something for myself, setting and keeping my own rules; I stopped doing it after Brexit because of food security worries (luckily unfounded, at least so far).
So this year yet again, no official challenge, yet we really have gone nearly all year without buying much veg; the only vegetables I've put on the list are onions, something I still haven't succeeded with yet--and one weekly carrot for the small daughter's lunchbox (somehow I didn't buy carrot seed until too late for this spring).
We really could have gone without these two, although I would have missed onions, as I use them every day (I'm trying again next year). My freezer is a third full of garden/allotment veg (the other two thirds are meat and berries); I have two shelves in my cupboard full of dried, pickled and preserved fruit and veg; and my fridge is half full of jars of fermented vegetables/kimchi. Not to mention the fresh veg still standing, waiting for harvest at both the allotment and garden.
Will I restart the Challenge next year? Can I officially go the whole year? I'm not sure! But maybe 2025 will be the year to try.
