It is among the most controversial and divisive ingredients chefs can add to a savoury dish.
But now an American pasty containing pineapple has been named one of the best on Earth at the World Pasty Championships.
The Pure Pasty Company from Virginia, US, trumped British entries with a dish it describes as the "Hawaiian pizza" of pasties in the competition's "Open Savoury Company" category.
It is the first time someone from the US has won the prestigious accolade at the awards, which are held every year at the Eden Project in Cornwall.
Its barbecue pulled chicken-filled pastry is made with sweet potato, courgette, red pepper, sweetcorn and pineapple, and aims to deliver both sweet and spice on one mouthful.
Behind it in second place was the Warrens Bakery from Cornwall with another unusual entry, this time a vegan yellow Thai pasty.
In previous years the category has been dominated by traditional British entries.
Mike Burgess, founder at the Pure Pasty Company, said: "We have always been focussed on fusion. We love to combine the traditional Cornish pasty with American dishes to come up with new ones.
"The chicken recipe is a progression on some barbecue pork we made and we wanted it to be different from the pork. We were aiming for something spicy with the barbeque sauce and sweet, but not too sweet.
"We wanted an element of fruit flavour, a bit like Hawaiian pizza. The pineapple is an important element of our chicken pasty, definitely.
"It is very bright inside, it has a normal deep brown but also reds and yellows as well as the orange of the sweet potato."
Eden Project spokesman David Rowe said: “There was a great spirit today at our seventh World Pasty Championships. The pasty bakers made heroic efforts to be here despite everything the weather could throw at them this week.
“Huge thanks to our friends from the Cornish Pasty Association for helping us deliver the event as fitting end of the first-ever Cornish Pasty Week.”
