I’m in southern Europe and I’ve been abroad for ages so don’t really miss anything much nowadays. Except Marmite. I have to trawl a load of Chinese supermarkets or specialist grocery stores to find it and it now costs me almost €10 a jar! Before Brexit it just wasn’t that pricey.
I also miss the root veg, swede, parsnip, the different types of beets and “proper” potatoes.
I also sometimes miss Cheddar, the local cheeses aren’t quite so melty and with a strong flavour, which i prefer for some dishes. I end up buying it from British week at Lidl, which is not great quality but hey ho.
Indian pickles, PG tips tea, that dodgy Nestle sterilised cream from the 70s etc. can all be found in the local Chinese supermarkets, so in that front we want for nothing.
crisps etc I prefer the local ones now, with a glass of wine, as is the norm here. In fact, I don’t think I could eat them without wine now!
Yes to less of a snacking culture and the food generally is better quality here and more seasonal, and there is less processed crap, which I really do not miss. I placed an order with the British corner shop for a gift for a friend and was shocked at how processed and low quality many of the products on offer were. Except for some of the zM&S biscuits. Although the crumpets were disappointing and tasted plasticky, but then maybe they were like that before and now my palate’s changed I don’t like them anymore? I think when you get out of the habit of eating something it never quite tastes as nice as you remembered it.
