I’m forever battling with DP over this. He’ll see the date on tomatoes or that they’re a bit wrinkly and start piling them by the food waste instead of chucking them in the oven to roast down into a sauce, or jiggling the meal plan to push back something less urgently in need of being eaten.
On the whole we’re pretty good – egg shells and coffee and banana peels get used for roses in the garden, we have a couple of “odds and sods” meals in the plan each week to use up random leftovers, and if we plan something like a bolognaise that needs celery, as pp example, we’ll make sure the next 800 meals include celery (WHY are celery packs so huge?!)
But DD is another “no crusts” git who also loves apples but hates the peel
and changes her mind on likes constantly. We definitely buy too much but busy lives don’t help – like a lot of environmental factors it comes back to households built around two people working full time, and commuting: where is the time to buy small quantities, daily? I’d love to be Nigel Slater just picking up something in the butcher then going to the baker then the grocer then my veg garden and orchard to get exactly what I need, but for most people a big shop once a week is much more doable.
I’ve had luck with the Olio app though, that’s reduced our waste a lot, and doing a big shop fortnightly instead of weekly. And going vegetarian – we’re now much more likely to root around the fridge and gather everything up to use. Whereas when we were eating meat it was more “cook meat, a carb, some vegetables”, and lots went wasted.
