Those attending any sort of festival or outdoors wedding during the summer months can usually expect to detect the whiff of hog roast in the air, or the tempting aroma of a burger van.

However, organisers and chefs who cater some of Britain’s top outdoor events say these traditional festival foods are falling out of fashion in favour of dinky sharing plates and light salads.

Daniel Maycock, who organises the Great British Food Festival, which takes place all summer across Britain’s country houses, said: "Old traditional things seem to be struggling, especially heavy foods in the summer heat – so hog roasts, big burgers, meat pies and mash that sort of british classic festival food. In, are lighter things, hallomi, falafel, even salads!"

Those who went to Wilderness last weekend were more likely to opt for crunchy radishes and colourful vegetables over a piece of charred pork, Caroline Hall, whose company Rocket Food has catered the upmarket festival.

She said: “Due to the heat wave, we’ve seen an increase in demand for lighter food at our parties this summer. Big hits were: Secret Smoked Salmon carving station, Lydersfarm Oyster beds with bespoke garnishes and seafood bars.
