A man has made social media users nostalgic for old-school crisps after finding a Golden Wonder packet from what he believes to be the 1970s. Taking to X, Donnie Maclean, from Scotland, explained that he found the crispy bacon-flavoured crisps while renovating his kitchen.'Hey @GoldenWonderUK, I'm renovating the house I bought recently. I just pulled a kitchen unit away from the wall and found these beauties,' he wrote, adding 'I'm estimating late 1970s. What do you reckon?!'The post gained one million views, with people marvelling at the packs’ fullness and the seemingly shorter ingredients list, made of five elements, compared to crisps these days.One said: 'A bag that's filled to the brim? You definitely don't see that now!' A second added: 'It's the lack of unnecessary ingredients that impresses me.''The good old days when a crisp packet had crisps in it,' said a third user. Another agreed, saying: 'That's a very generous portion of crisps in that packet.'It comes as ingredients from the 1970s have made a comeback, with some even being touted as health foods.While recipes such as prawn cocktail and spam fritters might not sound like an obvious staple for fitness fanatics, some favourites from the decade are proving popular with gymgoers. Donnie Maclean, from Scotland, found a nostalgic pack of Golden Wonder crisps when renovating his kitchenAmong the items making a return is tripe, a cheap butcher's cut that was traditionally boiled and served with onions, which is also becoming a trendy ingredient for foodies to incorporate into a curry or Korean-inspired BBQ.Tripe, the lining of a cow's stomach, was once a British comfort meal. It was cut into pieces and cooked down in onions, milk and water. It was then thickened with butter and flour, and dressed with parsley, cheese and vinegar.With more young people turning away from meat cut snobbery and to more divisive animal parts like trotters and chicken feet, tripe is enjoying an increased interest. However, boiling is no longer the go-to way to enjoy it.Now, its distinct taste is used in flavourful curries or grilled for East Asian-inspired BBQs. Meanwhile, corned beef was also often enjoyed in sandwiches in the 1970s - or at times served with mash and veg.This year, however, it’s become trendy, especially when cooked down into a crispy 'hash' and served with rice and eggs in a Filipino breakfast.Another ingredient making a return is condensed milk from Carnation, which was popular in desserts, often used as a key ingredient in creamy jellies or poured over them.Condensed milk is still used to make things nearly impossibly sweet - but now, the focus appears to have switched from desserts to drinks. One popular recipe is a Vietnamese-inspired coffee. Social media users marvelled over the 'generous' amount of bacon-flavoured crisps in the packet Nicknamed 'frog spawn' due to its pearly appearance, Tapioca Pudding - tapioca mixed in with milk or cream - was a popular school dinner staple from the 1950s to the 1980s. However, while the dessert itself is enjoying a comeback, too, it's now more popular as another sweet treat.These days, you'd be more likely to buy tapioca to make your own 'boba' pearls - the key ingredient in cult-favourite 'bubble tea'. It consists, in its most basic form, of black or green tea, milk, ice and tiny chewy balls of tapioca dough - shaken together like a cocktail and served with a wide straw.Originating in Taiwan in the 1980s, bubble tea 'cafes' and bars offering a dizzying array of creations have been on British High Streets and in shopping centres since the early 2010s and have become a fashionable hang-out spot for teenagers.But recently, they've been experiencing stratospheric growth - proliferating at an extraordinary rate, and all thanks to a surge in popularity on social media platforms such as TikTok, where these drinks have become a new viral trend.
