She says: “Doctors don’t understand. I’ve never been referred to a specialist or given any help. They think I’m just fussy and should change.” Bizarre as it sounds, Debbie, 30, has eaten nothing but crisps for 10 years, and for the past two, beef flavour Monster Munch have been every meal. Debbie says: “Gerald wanted to take me out to dinner or cook for me at home but, whatever he did, I couldn’t eat anything. Despite cheese and onion being a bonafide classic, not a single taster guessed it correctly. Four detected cheese (though one commented it was “bad cheese”), but the sweetness of the caramelised onions threw most off. Someone even guessed these were ‘strawberry’ flavoured crisps. Manomasa Chipotle And Lime 0/12 correctly identified the flavour

Debbie says: “I know people must think it’s strange but it’s not hurting anyone else and my heart hasn’t stopped yet.Even when she started seeing Gerald in 2003, she couldn’t change her diet and it caused awkward situations in their relationship’s first months.

Pringles, Spence says, are designed to work with the fact that 75 to 95 per cent of what we think we are tasting we are really smelling. “With a crisp like that, it goes into the mouth in a particular way, so you can just add more of the aromatic stuff to one side of the Pringle, and more of the taste to the side that’s likely to go on the tongue.” It involves breaking down foods to a molecular level to identify flavours that go together, such as apple pie and cheese or banana and bacon.

Prosciutto isn’t the strongest flavour in the world, and all taste testers found it was entirely overpowered by the formaggio cheese. There were a few left-field options too. “Cranberry sauce” and “strawberry” were two of the kinder suggestions, while one suggested a brand new flavour which might set the culinary world alight: “mould.” M&S Maple Bacon 5/12 correctly identified the flavour Debbie doesn’t take any vitamin supplements and hasn’t eaten anything green since she was a child, but nonetheless she insists she feels fine. He says: “It used to scare the living daylights out of me when we first got together, I worry about the damage she’s doing to her body.I would like to change, I just don’t know when it’s going to ­happen and what it’s going to take. I worry about the future, I would like to eat normally but I don’t know how to get there.” At 5ft 3ins, she looks to be around a size 10 or 12, but she hides her figure under shapeless clothes and never buys new outfits.

She says: “I was ­terrified of flying but also very worried that I wouldn’t find any Monster Munch in Spain. It may also explain why crisp ingredients seem to vary so little. “You only need a very small added aroma to give a big effect on taste and flavour. A tiny percentage of an odorant can completely change how you identify it, if you can identify it at all,” says Spence. Overall the results were as follows… Waitrose West Country Cheddar And Caramelised Onion 0/12 correctly identified the flavourWe usually add some sweets and Coke in that trolley for Luke – sometimes the cashiers ask if we’re having a party!” How can it be that you can buy almost any kind of crisp flavour – from chilli to cappuccino – and yet the ingredients that go into them boil down to the same few chemicals and seasonings? Why, indeed, as Kevin asks, do all beef crisps taste roughly the same – and usually without having come from anywhere near a cow? Crisp companies, Spence says, consider more than just the ingredients when they are developing recipes. Crunch, for instance, is a clever marketing ploy, he says. “Noisy food can help draw attention into our mouths when we’re eating so we pay more attention to the flavour and tend to get more from it.”

Currently, Walkers have made all of the flavours vegetarian but not vegan, so not right now, but above you’ll find a good option if you’re craving something very similar or how about finding out the answer to can vegans eat wotsits.For the next eight years she only ate Walkers crisps and for the past two years beef flavour Monster Munch has been the only meal she could stomach. She insists she doesn’t know her size and, unlike her teenage years, doesn’t any longer obsess about her weight or starve herself. A good crisp, then, will bring the perfect balance of sweetness, sourness, saltiness, bitterness, savouriness (also known as umami), and the sixth taste: richness (also called kokumi). It’s umami and kokumi that “give that mouth filling, satisfying sensation when you put them in foods”, says Spence. Crisps can be political, too. “It’s the ultimate bastardisation of any cuisine,” says Sainsbury. “If you think of a Thai green curry, a Thai green curry crisp is as far removed from Thai green curry as you can possibly get. It’s just the essence of that on a crisp.”
