EXCLUSIVE I've been arrested at the airport for eating fermented foods including 10-year-old butter and seal blubber - why I do it
The thought of eating any fermented food - let alone the likes of seal blubber or cheese - is enough to make anyone gag.
But Dr. Johnny Drain, from Birmingham, has been doing so for years - having devoured everything from whale mouth and seal blubber to artichokes and stingless bee honey, all fermented.
The chef's passion for fermentation - in which microorganisms such as bacteria and yeast convert the carbohydrates in foods to create a preserving effect - started as a child, when he and his grandma tried the process on yoghurt.
He then took it a step further after getting a PhD in Materials Science at University of Oxford, combining his passions with food, working in Michelin-star restaurants all over the world.
Ahead of the release of his debut book, Adventures in Fermentation, Johnny tells MailOnline: 'I had this real epiphany of like, f**k, everything delicious is fermented.
'And basically spent the last the 10 years of my life since researching fermentation, pushing pioneering new techniques within fermentation and also teaching.'
But Johnny's love of fermenting food has got him into trouble at the airport on a number of occasions - due to the sheer amount of equipment he has to lug around, and he jokingly describes his suitcase as 'a cross between a drug smuggler and a bomb maker'.
He explains: 'There are little sachets of white powders which contain spores for fungi that I teach people to grow that you can make soy sauce or miso paste with.

'And there's white powders, and then there's little machines that bubble air through things and temperature devices. So I look very dodgy.'
Johnny admits he was even arrested at Gatwick Airport on suspicion of drug smuggling in 2020, on the way to Portugal, having just returned from Paraguay via Madrid.
'I got stopped,' he tells us. 'They told me they found traces of drugs on my on my bag, and then they had all of this stuff.
'And when someone asks you "So, what do you do?" And you explain to them, "Well, I just sort of go around the world eating food and helping people ferment things".
'They were like "Well, that's a that's not a proper job!"'
Johnny continues: 'They were very polite.
'They said "Can we arrest you?" And I sort of said "Yeah, okay".'
The chef was detained by police and given a full body scan to check if he was carrying drugs inside his body.
'I was formally arrested, and then they switched on this giant X-Ray machine,' he recalls. 'I went in there and obviously I hadn't swallowed any drugs. So they let me go.'
With his connecting flight looming, Johnny was given a police escort to the awaiting aircraft, as his fellow passengers cautiously watched on.
He laughs: 'I was flanked by these two policemen with machine guns, and everyone else on the flight was like "Who's this guy?"'
Johnny has tried plenty of different fermented foods over the years, including tiny icefish in Japan, and canonical French cheeses in Patagonia.
But it was ten-year-old butter that really left a lasting bitter taste for Johnny, when he tracked it down in Marrakesh.
Describing the soured taste, he says: 'It really slaps you in the face, like a blue cheese, but with this bitterness and pungency. It's acrid.
'It's like this real spice that slaps the back of your throat.
'It's not for everyone, but definitely really interesting.'
Johnny's debut book Adventures in Fermentation will be released on June 12
Although it's unlikely many people are going to follow in Johnny's footsteps of carrying around fermentation equipment, there's one must-have travel item he uses that actually makes things taste better.
Johnny never flies without his Aeropress, a compact coffee maker, in his suitcase.
He says: 'I just take that and a bag of good quality coffee grounds with me.
'And it means that I can be in the airport, I can be in the world's s**ttest hotel, and, instantly in the morning, all I need is a kettle and I can make an unbelievably decent cup of coffee.'

NHS spent £100 million on post last year
The NHS spent at least £102 million on posting letters last year despite pledging to go digital because of unreliable deliveries. The amount spent on sending mail, which can regularly arrive late and cause missed appointments, was up by 12.5 per cent on the year before, according to new research by the Taxpayers' Alliance. The research results have been released as the health service is about to get £30 billion more over three years in Rachel Reeves's spending review this week, to the detriment of other public services. They also revealed the NHS could make major savings in electricity and laundry costs, as well as reducing the eight million missed appointments that occur each year. The Telegraph previously revealed that the Royal Mail was introducing a new NHS barcode to cut late deliveries and the risk of missed appointments. But health officials have also pledged to do more to communicate with patients online and through the NHS app. Last week, the Department of Health said the app would become the default method of communication for patients seeking appointment reminders, screening invitations and test results as part of a major investment that would mean 50 million fewer letters are posted each year. The research from the Taxpayers' Alliance found that at least £102 million was spent in 2023-24 across 120 NHS hospital trusts, an average of £850,000 each. The researchers said this was a 'growing expense' with the costs rising by 12.5 per cent on the £90.3 million spent in 2022-23. Previous research found that as many as one in four of the eight million appointments that patients miss each year were because letters to patients arrived after the date of the planned appointment. Simon Cook, a research fellow of the Taxpayers' Alliance, said the public 'expect the NHS to double down on cutting any inefficient and wasteful expenditure'. 'With the health service facing financial pressures, there are huge savings to be made through simple, common sense changes,' he said. 'Ministers must recognise that sometimes the biggest savings don't always require major reforms, just the will to act.' The research paper also found that the NHS could save more than £150 million on electricity costs if it utilised its buying power. It said the average cost of electricity across NHS trusts in England was 30.5p per kWh in 2023-24, which was 'typically the rate that medium-sized businesses pay'. £154m potential laundry savings The NHS is the biggest single employer in Europe and 'if every NHS trust paid the average extra-large non-domestic consumer price of 22.6p, the saving would amount to £154 million in 2023-24,' the researchers said. The researchers also found significant discrepancies across the country in the amount being spent on laundry. While the NHS spent £270 million to launder 555 million items at an average cost of 48.7p per item, some areas achieved lower costs of 25p per item, while others spent £1.20. A Department of Health and Social Care spokesman said: 'This government inherited a broken NHS with wasteful spending, in desperate need of reform. 'Yesterday, we announced major investment in the NHS app to turbocharge our digital revolution – saving hundreds of millions in taxpayers' money spent on stamps and envelopes, and enabling push notifications and reminders to help cut missed appointments. We are also cutting NHS energy bills through solar power and renewable energy – delivering further savings for the taxpayer. 'Through our Plan for Change, we are reforming the NHS to ensure that every penny is spent on what matters most.' An NHS England spokesman said: 'Millions of patients are already receiving appointment reminders, screening invitations, and test results direct to their smartphones from the NHS, saving millions of pounds, avoiding the need for letters and freeing-up resources for patient care. 'People without access to smartphones and elderly patients will still receive messages through traditional routes such as letters to ensure they don't miss important information. 'The NHS is continually exploring ways to achieve the best possible value for taxpayers, including making targeted investment in technologies that can enable us to optimise our resources and boost productivity.'

Real risk Rachel Reeves's spending review will be about the departments that have lost out
"It's a big deal for this government," says Simon Case. "It's the clearest indication yet of what they plan to do between now and the general election, a translation of their manifesto. "This is where you should expect the chancellor to say, on behalf of the government: 'This is what we're about'." As the former cabinet secretary, Mr Case was the man in charge of the civil service during the last spending review, in 2021. On Wednesday, Rachel Reeves will unveil the Labour government's priorities for the next three years. But it's unclear whether it will provide all that much of an answer about what it's really about. Unlike the Autumn budget, when the chancellor announced her plans on where to tax and borrow to fund overall levels of spending, the spending review will set out exactly how that money is divided up between the different government departments. Since the start of the process in December those departments have been bidding for their share of the cash - setting out their proposed budgets in a negotiation which looks set to continue right up to the wire. This review is being conducted in an usual level of detail, with every single line of spending assessed, according to the chancellor, on whether it represents value for money and meets the government's priorities. Budget proposals have been scrutinised by so called "challenge panels" of independent experts. It's clear that health and defence will be winners in this process given pre-existing commitments to prioritise the NHS - with a boost of up to £30bn expected - and to increase defence spending. On Sunday morning, the government press release trumpeted an impressive-sounding "£86bn boost" to research and development (R&D), with the Science and Technology Secretary Peter Kyle sent out on the morning media round to celebrate as record levels of investment. 14:18 We're told this increased spending on the life sciences, advanced manufacturing and defence will lead to jobs and growth across the country, with every £1 in investment set to lead to a £7 economic return. But the headline figure is misleading. It's not £86bn in new funding. That £86bn has been calculated by adding together all R&D investment across government for the next three years, which will reach an annual figure of £22.5bn by 2029-30. The figure for this year was already set to be £20.4bn; so while it's a definite uplift, much of that money was already allocated. Peter Kyle also highlighted plans for "the most we've ever spent per pupil in our school system". I understand the schools budget is to be boosted by £4.5bn. Again, this is clearly an uplift - but over a three-year period, that equates to just £1.5bn a year (compared with an existing budget of £63.7bn). It also has to cover the cost of extending free school meals, and the promised uplift in teachers' pay. In any process of prioritisation there are losers as well as winners. We already know about planned cuts to the Department of Work and Pensions - but other unprotected departments like the Home Office and the Department of Communities and Local Government are braced for a real spending squeeze. We've heard dire warnings about austerity 2.0, and the impact that would have on the government's crime and policing priorities, its promises around housing and immigration, and on the budgets for cash-strapped local councils. The chancellor wants to make it clear to the markets she's sticking to her fiscal rules on balancing the books for day-to-day spending. But the decision to loosen the rules around borrowing to fund capital investment have given her greater room to manoeuvre in funding long-term infrastructure projects. That's why we've seen her travelling around the country this week to promote the £15.6bn she's spending on regional transport projects. The Treasury team clearly wants to focus on promoting the generosity of these kind of investments, and we'll hear more in the coming days. But there's a real risk the story of this spending review will be about the departments which have lost out - and the promises which could slip as a result.

Northampton General patient records to go digital
All patient records at a hospital are to go digital as part of a major step "in modernising patient care".The new Electronic Patient Record (EPR) will be switched on at Northampton General Hospital (NGH) from Saturday 28 June. It has been developed by the software system Nervecentre, and is designed to bring all patient notes and information into "one single, secure digital format".William Monaghan, from NGH, described it as a "pivotal moment" and said he hoped it would mean "safer and more co-ordinated care". A hospital spokesperson said the electronic system would "enable clinical teams to access real-time information about a patient's care, helping them make quicker, safer and better-informed decisions". 'Teething problems' Patient records are currently stored in a combination of paper files and digital systems, but will be replaced by "a central, streamlined platform that enhances efficiency and reduces duplication". Mr Monaghan, group chief digital information officer, said: "This is a pivotal moment for NGH and our patients. "The new EPR system puts essential information at our clinical teams' fingertips, helping them deliver safer, more co-ordinated care."While there may be a few teething problems as we go live, this investment in digital infrastructure will transform how we work, giving our teams more time to focus on what matters most: caring for patients."The hospital said staff would be using secure, hospital-owned mobile devices, like tablets and iPhones, at patients' bedsides. It means staff will be able to view the latest medical information instantly, spend less time on administration, avoid asking patients to repeat their history many times - and improve co-ordination between departments and patient information will be kept secure, it confirmed.
