Tomlinson points to the amalgamation of crisp companies as a reason for the decline in unusual flavours after the 80s (Smith’s, for example, was bought in the 90s by PepsiCo, which owns Walkers; its Bovril flavour didn’t make the cut). From there, crisp flavours became fairly standardised. Sarah Lawson, the marketing manager for the British brand Tyrrells, says 70% to 80% of its sales come from four flavours: lightly salted, salt and vinegar, cheddar and chive, and sweet chilli. I’d suggest keeping things rather simpler in the form of salt and a sprinkling of smoked paprika, though feel free to substitute spices of your choice, or indeed a little lemon zest, which is always a good match with leafy greens. I’m less keen on Baxter and Dimbleby’s final squeeze of lemon juice though, simply because it undoes all my previous hard work on the crispness front. You can add any flavouring you like…. I am totally going to be experimenting with this. But youhave the freedom to think up any number of random crisp flavour concoctions as you like, perhaps even some that aren’t available commercially. We try to make as many of our recipes adaptable as we can, because everyone has different tastes.

Don’t omit the soaking process of your potato crisps. I recommend leaving them for at least 30 minutes but you can leave them for a couple of hours before rinsing your potato slices. Paul said: "I was supposed to be filming for Channel 5 the next day, a film called ‘Hard Work Pays Off’, but I had to call them to say I couldn't come in. Kale crisps: the best thing since sliced sourdough, or a massive hipster swizz? Can anyone explain the secret of kale’s success – and suggest what I should do with all my leftover curly kale? How is it possible that, in 60 years, British shops have gone from selling one crisp flavour to selling hundreds – and why are seasonings becoming more unusual? What led Kettle Chips to release a “truffled cheese and a splash of English sparkling wine” flavour in October? Was there a mad scientific breakthrough that caused Walkers to release bratwurst, paella, haggis and spaghetti bolognese crisps in 2010?There isn’t a single member of my family who doesn’t like crisps. I mean, there aren’t manycrisp hatersin the entire world, surely!?So, I knew these would go down well. Adding your Own Flavour to Homemade Crisps

Hovey works on roughly 12 new flavours at any one time, but he says only half of these see the light of day. “I spend a lot of time working in the future. It takes me eight months to make a seasoning, so I’m trying to make something that’s going to be bang on trend in eight months’ time.” Sometimes this means the chef misses the mark – his team have been known to cry: “What are you making?!” – while other flavours make it to taste-testing groups that ultimately disapprove. So, what is next for crisps? Hovey believes the demand for “bolder and bigger” flavours isn’t going anywhere, while Berenstein says that nothing – not even a climate apocalypse – can break the seasoning spirit. There are many different types of kale. The leaves can be green or purple, and have either a smooth or curly shape - we used green curly kale in this recipe, which is what gives it the vibrant green colour. But you can use a mixture of purple and green, which would give a lovely mixture of colour. Put the kale in a large bowl and add the oil. Massage it into every dimple in the leaves, then toss with the seasoning. Spread out in a single layer on two large baking trays lined with baking parchment and bake for about 30 minutes, turning the trays round half way through cooking. Of course there are so many options like these lemon and tomato potatoesor even some simple roast potatoes. But, I wanted something new.

Kale might just be one of the most nutrient dense foods on the planet, which is why it is often referred to as a "superfood". A member of the cabbage family, kale is a cruciferous vegetable like cabbage, broccoli, cauliflower, collard greens and Brussels sprouts.

It’s also super simple to make these baked crisps, albeit a little more time consuming than simply grabbing a bag of crisps from the cupboard. However, it’s a good way to control the portion; you’re less likely to eat so many if they take time to prepare. Original and best? Despite the plethora of choice, traditional flavours are still popular. Photograph: Les Gibbon/Alamy But the market changed again, Berenstein says, roughly a decade ago. “It’s not that there’s been any kind of technological breakthrough that has allowed for these things that were previously only dreamed of,” she says. “It’s a new understanding of consumer desires and a new pace of production. It’s a bloodbath out there in the supermarkets.” New, limited-edition and mystery flavours attempt to capture the market by “promising something new and different”, she says.Tassy Goodall, a chef who works with Sainsbury’s to develop its Taste the Difference crisps, says that the UK crisp market has been influenced by global food trends. “Because the UK is so multicultural and we’re quite well connected with different cultures through restaurants specialising in different cuisines like Middle Eastern food and regional Indian dishes, it gives us more leeway to use more unusual or interesting flavours.” For reasons of hygiene and safety, personal grooming products, cosmetics or items of intimate clothing cannot be returned. Climate change is going to change agricultural production: people will eat less meat, there will be finite availability of certain kinds of produce, or at least a higher cost to pay,” she says. “But I think, because flavour is potent in very small quantities, it’s one of the things you’ll be able to expand.” As our food options shrink, Berenstein argues, artificial flavourings could become more prevalent as we look to mix up our limited diets.
