I rarely buy fresh produce from supermarkets. Most of mine comes from Riverford which is a group of organic farms in the UK, and their food reminds me of the stuff that used to come out of my parents' garden when I was much, much younger, but mainly because I like to know where my food comes from. They do buy some of their fruit and veg from abroad, but it is all traceable and has to meet strict UK organic standards (which are the same as or better than EU standards). I tend to buy their meat too, in spite of the price, but as I only eat meat occasionally the price does not matter.
I find that most supermarket fruit and veg, even their organic produce, is watery and pretty tasteless, although there are a few exceptions. Sainsbury's organic potatoes are very good, and the onions and cucumbers I get delivered by the milkman are excellent, but from either source their tomatoes are only ever any good for making sauces or putting in highly spiced foods such as curries - they are very similar to the "frying tomatoes" we used to get from our local greengrocer, I.e. too soft for eating but not soggy enough to bin (or plant). I did give in to temptation and bought a couple of pears from Tesco a fortnight ago for ripening up but they are still like bricks. I should have known better - I made it a rule some time back never to buy fresh from Tesco. Sainsbury's also do a nice organic bacon too - good for when I get the urge to eat bacon and don't want enough meat to warrant getting it from Riverford. I do buy class A human grade chicken from the supermarket (and also sausages) but they are for the dog, although I must admit to pinching some of the chicken drumsticks for myself on the odd occasion.
Tinned foods I usually get from the supermarket - the organic equivalents can be quite or very expensive - although our town market and our local pound shops are good for some items, all well-know grand names and usually a few days off their best before dates but very good for batch cooking.
I am writing this as I crunch through what is supposed to be a Granny Smith apple.
You would love the Granny Smiths I have in my fridge. I won them in a raffle (!) along with pears, sweet apples, a marrow, a pumpkin, all grown by fellow greyhound owners on their allotment and all organic. They are exactly how Granny Smiths ought to be.
…..because of the no-frills approach to the store (BYOB bags, products sold out of shipping containers)…..
There used to be shops like this locally in the 1980s, but they weren't Aldi or Lidl. I can't even remember what the company name was, but they seemed to take over empty shops and pile them with boxes of all sorts of packets and cans. There are 3 Aldi stores, all about 3 miles away, and a Lidl just up the road but I rarely buy food from them, although for non-food items (and in the case of Aldi electrical items) they are fine. To me their food seems to be the cheap supermarket equivalent of a KFC - for desparate emergencies only (even my dog won't eat anything from a KFC!).
I do miss the food I used to have in Austria. My friend's mum owned a village store. Fruit and veg were all local produce. The milk used to come in churns from the village dairy and the cream used to be scooped from the top of the churns as and when required. Butter and cheese came in huge blocks to be weighed out as required. Anything left over at the end of the day was used to feed us with a generous helping of locally produced beer to wash it down (or good old-fashioned Fanta - not the chemicals that are sold under that name now). The highlight of our day was to scoop the milk out of the bottom of the churns - it was thick and yoghurt-like, but not "off". As for when I was in other villages, I do miss the SPAR grocers that abounded - a group of local stores that sold locally produced fresh produce, although their milk came in bottles and their butter and cheese ready weighed and wrapped. The SPAR grocers in the UK were never like that. Even the small village stores here vary so much, but some are superb.
