Bad waiters, bum tables, little rip-offs, big cons, old fish, cheap meat, yesterday’s soup and tomorrow’s gastroenteritis… The splenetic humorist tells us how to avoid the lot, and even come out of it with free champagne and a dish named after you by way of apology.

There are moments in our lives, and throughout the year, when we come together with our friends and family, and food plays a huge part in turning these moments into something special. Traditionally, many of these occasions call for meat – whether it’s roast beef for Sunday lunch, or burgers at a BBQ – but Mary wants to show us that vegetarian cooking can be just as celebratory and special.

Our food system is in crisis: soaring rates of obesity and diet related ill-health, environmental degradation and escalating greenhouse gas emissions as well as record levels of waste which deny food to the hungry. How do we create a system that enables all citizens to eat affordable, healthy food regardless of where they live and what they earn?  Could Brexit create a solution? Is a Food Act an answer?  Boycott proposes a complete reimagining of how we farm, how we shop and how we eat. Rosie Boycott chairs the Mayor of London’s food policy unit. Chaired by Dan Saladino, presenter/producer of BBC Radio 4’s The Food Programme.

For a number of years The Parson and The Publican have travelled the highways and byways in search of refreshment for body and soul. With many years between them of accumulated wisdom on matters pertaining to pew and pump it was but a short step to committing their experiences to print. The authors have scoured Worcestershire, Herefordshire and The Wye Valley to amass these tales, which are delightfully illustrated with watercolour sketches from the brush of the Publican. Some of the places in their delightful book are well known, while others are more obscure but, never discouraged, our plucky pilgrims get out the map, freely exchange opinions and then do precisely what the driver wishes. Not for them the wonders of the 'Sat Nag'. Rather, instinct and an unwavering nose for musty hassocks, malted barley or fermented apple juice draws them ever onwards.

We look at the future of farming in Britain and ask what ‘better’ might look like: better for farmers, better for people who need food. What are the issues that matter most? Diversification, ‘big-agri’ ownership, the relationship with supermarkets, the mental health of the people who work the land, the land itself or the quality of produce? Hughes is the National Trust's General Manager for Pembrokeshire, overseeing more than 30 tenanted farms, Blackmore (Harper Adams) specialises in farm engineering, Boycott is Food Advisor to the Mayor of London and Carrington is a young farmer from Hereford.

Many of our own gardens contain an abundance of edible and medicinal plants, grown mainly for their ornamental appearance. Most gardeners are completely unaware that what they have actually planted is a rather exotic kitchen garden. The Garden Forager explores some of the most popular garden plants that have edible, medicinal or even cosmetic potential. Nozedar’s recipes and remedies are exquisitely illustrated in watercolours by Lizzie Harper. She talks while Harper illustrates live.

With an increasing population, climate change and concerns about food (in)security, new and innovative farming methods are required. Steve Dring started the UK’s first underground farm based in disused air raid shelters, growing herbs and salad plants.

The extraordinary story of Mary’s Meals: after watching a news bulletin about war-torn Bosnia, two brothers agreed to take a week’s hiatus from work to help. What neither of them expected is that what began as a one-off road trip in a beaten-up Land Rover rapidly grew to become Magnus’s life’s work – leading him to leave his job, sell his house and direct all his efforts into feeding thousands of the world’s poorest children. He talks to Sarah Crompton.

An hour of beer tasting with one of Britain’s most entertaining connoisseurs.

The author of Let Me Tell You About Beer is living the beer dream. Not only does she write extensively about the world's favourite drink, she also works with chefs to create beer and food extravaganzas in venues as diverse as Michelin-starred restaurants to local pubs, and is invited to judge at beer competitions from London to Brussels and Amsterdam to America.

Her reputation for having a fine palate and fun approach to all things brewed also translates to actually making beer, and some of her collaborative beers have gone on to become huge successes for the breweries Melissa made them with, never profiting herself.
