While some might rely on a sachet of quick oats for their daily porridge fix, there are oat aficionados who will happily steam, roll, cut or grind their own. There's a world of flavour and texture to explore, and for the most accomplished out there, Scotland hosts an annual World Porridge Making Championship — The Golden Spurtle. 

Eating can be a simple pleasure, but for some it's a struggle. Food aversions manifest in many ways, from simple picky eating to outright disgust. Very few of us don't have at least one or two foods that we avoid. Sometimes it's about taste or texture, other times it's attached to a bad memory, such as a bout of food poisoning. Whatever the cause, is it possible to shift our aversions?

Digging for truffles is like digging for buried treasure: a good haul can earn you a pretty penny and the activity can attract a rogues' gallery of characters keen to keep the booty for themselves. Rather than relying on competitive (and sometimes dangerous) foraging, Australia is a world-leader in truffle farming. But growing these fickle fungi is a years-long endeavour, and harvesting them requires the assistance of a four-legged friend.

Who doesn't love a passionfruit sponge, jam roly-poly or nice fluffy scone? Many of these classic recipes have been shared via community cookbooks, compiled by community groups and sold to raise funds for different causes and organisations. These books can become time capsules, revealing much about the social and political fabric of a community at a particular point in time.

Cyclists at the Tour de France consume unfathomable amounts of food as they compete in the nearly 3,500-kilometre race over 21 days. Consistent eating can make the difference between securing the yellow jersey or suffering an early exit. But as they wend their way around France, can cyclists enjoy the regional cuisine? Or does the local fare remain tantalisingly out of reach?

Everyone's a critic, but there's an art to the well-considered, expert restaurant review. Besha Rodell is an award-winning writer and the chief restaurant critic for The Age. She's written for The New York Times, Food & Wine, Bon Appetit and many others. Now she's written a memoir, Hunger Like a Thirst, which is about her life, her love of food and how good criticism can become an integral part of a city's culinary life.

In episode two of our series on food in space, we're travelling beyond the exosphere to discover how we might feed ourselves during voyages into deep space and how that technology could change what we eat here on Earth. We learn about new farming techniques optimised for hostile environments, the Australian plants hitching a ride to the Moon in 2026, and a protein source that can be manufactured 'from thin air.'

Space: The final gastronomic frontier. For the brave souls who venture far above the world, when they get peckish, can they rely on more than a floating tin can of food? The first meal in space was beef and liver paste squeezed from a tube, but what do we find in the space kitchen of today? Food in space is our next culinary adventure.

What's on the menu this week? For many Australians, food is an adventure with limitless potential. A lamb roast on Sunday, a meat pie at the football, and perhaps a toastie with warrigal greens, kimchi and burrata at the local café. Our palate embraces everything from meat-and-three-veg simplicity to unique flavour combinations incorporating foods from all corners of the globe. How did we get here?

What would a birthday or a wedding be without cake? Celebration cakes are a signifier of occasion, sometimes requiring superhuman effort to bake and decorate. We explore the surprisingly recent history of the celebration cake, uncovering the role of the British royal family, The Australian Women's Weekly Children's Birthday Cake Book, and our evolving relationship with time itself.

You say tomato, I say… bleurgh. How is it that we can have such different experiences of the same foods? Taste and flavour: What are they and how do they work? We meet some of the top flavour scientists working today, including the researcher who discovered that there are 'supertasters' among us.

What characterises Australian food? We're a nation adept at making first-rate versions of food drawn from all corners of the globe, but our palates are less familiar with the foods of our own backyard. For millennia, Aboriginal and Torres Strait Islander people have cultivated and enjoyed uniquely Australian foods. So, why are these ingredients still so hard to find on supermarket shelves?

Many of us imagine that an athlete's diet consists of sports supplements providing carefully calibrated doses of carbohydrates, protein and electrolytes, but for ancient Olympians, a diet of cheese or figs was seemingly enough. In truth, whole foods are still the most important part of an athlete's diet today, as we discover on our culinary tour of the sporting world.

The egg is an extraordinary thing. In the pantheon of miraculous food chemistry, it takes on a range of essential roles. From helping cakes and soufflés to rise, to bringing disparate ingredients and flavours into a unified whole. They can also take on a starring role, whether fried, scrambled or poached. Eggs frequently appear in art, literature, design, and philosophy, too, and they are at the heart of the age-old paradox: Which came first, the chicken or the egg?

Australians don't always see eye to eye on election day, but there is one unprepossessing foodstuff that seems to straddle divides of age, geography, ideology and class: the sausage. How did the humble sausage come to be the food that fuels election days in Australia, with its name now synonymous with the democratic act?

What is appetite? Many happily succumb to it, while others struggle against it through willpower or even pharmaceuticals. But what are the biological, cultural and psychological mechanisms that make us want to eat? These questions are increasingly complicated in this era of unprecedented abundance and ubiquitous food.

In times of war, food and nourishment can determine victory or defeat. Welcome to the world of military food. Armies once lived off the land, but now they can live off a sealed, freeze-dried pouch. Imagining, making and storing combat-ready food leads global food science, which means that each and every one of us eats a little like a soldier.

In many religions, the key moments of ritual centre around food. Whether it's Eid al-Fitr, Passover or Easter Sunday, these feasts mark the passing of time and have bounty and renewal at their heart. In this episode, we pull up a chair at Easter and Passover celebrations around Australia and abroad, and en route we learn about some of the more ancient rituals that underpin these feasts of faith.

If you were to list the world's best bakers working today, Richard Hart's name would have to be right near the top. After honing his craft at big-name bakeries in California, he teamed up with the world-famous Noma to open Hart Bageri in Copenhagen. His skills with sourdough are so well-known, he was even namechecked on The Bear. Richard recently published his first book. It's called Richard Hart Bread.

When the bread baking craze took off during the pandemic, many of us encountered sourdough starter for the first time: a concoction of flour and water playing host to a colony of micro-organisms — most importantly: yeast. Without this single-celled fungus, we would have no leavened bread, no wine, no beer and no spirits. So, what role does it play? And how long have humans partnered with this miraculous organism?
