Gen Z are spicing up the traditional Sunday roast - with hot sauce, kimchi and avocado fast replacing roasties, gravy and Yorkshire puds.A survey of 2,000 people found people aged 18 to 29 are changing the traditions of a roast dinner more than any other generation.Lightspeed, which conducted the research, found two in five Gen Z respondents (39 per cent) like to add ketchup, a quarter (26 per cent) dollop on mayonnaise and just under one in four (23 per cent) are opting for hot spice.Almost one in five (19 per cent) regularly use chili oil, one in seven (14 per cent) smear hot honey on their Sunday favourite, while the same amount do not use gravy. Some 12 per cent have also ditched the Yorkshire Pudding altogether.In a further blow to tradition, 14 per cent have swapped out roasties for mash.Other regular Gen Z roast additions include kimchi (9 per cent), avocado (7 per cent) and sriracha (7 per cent).However, it's not just the younger generation changing the timeless tradition.Brits of all ages are swapping roast potatoes for sweet potatoes (12 per cent), adding jalapenos (8 per cent) or a traditional side for mac & cheese (11 per cent). The traditional Sunday roast is being spiced up by younger people, a new survey has found Gen Z are spicing up the traditional Sunday roast with more exotic dishes like kimchi Seven per cent of Gen Z respondents said they like to add avocado to a Sunday roast (file pic)More than a third of those making changes say it is to eat more vegetables (35 per cent), make the meal healthier (34 per cent), have more protein (22 per cent) or more fibre (20 per cent).But in defence of the old favourites, more than two thirds (68 per cent) insist roast potatoes should never be removed, followed by meat (65 per cent), gravy (63 per cent) and Yorkshire puddings (60 per cent).The traditional roast itself remains as popular as ever, with the average Brit already tucking into 11 Sunday dinners this year. Beef is the nation's favourite roast meat on 32 per cent, ahead of chicken (25 per cent) and lamb (19 per cent).When asked which one classic dish restaurants should never mess with, Brits still put the Sunday roast top (18 per cent), ahead of the full English breakfast (15 per cent) and fish and chips (14 per cent).Four in five Brits (81 per cent) want more restaurants, pubs and cafés to bring back traditional British dishes which remind them of childhood, while more than three quarters (77 per cent) would pay extra for meals made using British ingredients.More than a quarter (27 per cent) would even pay over £5 extra, while 71 per cent are more likely to order a dish if the menu tells them where in Britain its ingredients came from.Award-winning chef Sally Abé, who has recently opened her first standalone restaurant Teal, a high-end British bistro reimagining traditional dishes, said: 'Diners are far more adventurous than they were ten years ago.'Ingredients that might once have felt niche, like celeriac, fermented vegetables or offal, are now much more widely accepted when they're presented well.'Younger diners in particular have grown up with a wider range of global flavours, so experimenting with traditional dishes doesn't necessarily feel unusual to them.'Even something as familiar as a Sunday roast can evolve, whether that's through different vegetables, spicier flavours or new accompaniments.'But at the same time, there has been a real return to comfort and nostalgia.'People still want dishes that remind them of childhood or classic British cooking, but they expect them to be made with great ingredients and executed really well.'
