St Brigid of Kildare is one of the three patron saints of Ireland and has a strong connection with food and farming. St Brigid’s day falls on 1 February and traditionally marks the beginning of spring and the start of the agricultural year.

In 2023, the Republic of Ireland designated the day a public holiday if it falls on a Friday, and failing that the first Monday of February, but the day has long been celebrated in a variety of ways. People make St Brigid’s crosses to a variety of traditional designs, using them to protect farm animals and ensure a good harvest. There are special foods too, and other ritual celebrations, some of which delve in the pagan past.

Caitríona Nic Philibin has studied the folklore surrounding St Brigid and shared some of the stories with me.

No apologies for once again casting my net in the fruitful waters of Basque cuisine and history.

There is a pintxo — those tasty bites of stuff on a toothpick — that consists of a plump Cantabrian anchovy, a pickled guindilla pepper and an olive. Some people reckon it is the original pintxo, invented by one of the regulars at a bar in San Sebastián. Others are not so sure. Everyone agrees, however, that it owes its name — the Gilda — to Rita Hayworth, who starred in the movie of that name.

Last time I spoke to Marcela Garcés, we didn’t have time to talk about the Gilda. This episode fixes that omission.

I also had to contact Chris Beckman again, to see if he could enlighten me on what he calls the Swedish Anchovy Conundrum.

A thorough trawl in 2020 brought to light more than 40 different kinds of policies around the world designed to improve diets to deliver better nutrition and health. And yet, the vast majority of people do not eat within dietary guidelines. If anything, diets — and with them health — are getting worse in many places. What’s the problem? Maybe, it is that the people who devise the policies are too far away from the lives of the people they’re trying to help.

That’s the gist of a new paper from a group of researchers in the UK. They argue that “a fresh approach is needed, one that considers the full picture of people’s realities”. Corinna Hawkes, lead author on the paper, took me through some of those realities.

For a long time people have suspected that there is a kind of logic to what people buy as they have a bit more to spend on food. First, they change from coarse grains — things like sorghum or millet — to fine grains, wheat and rice, maybe corn. Then they switch up to protein from animal-sourced foods. This logic was even considered something of a law, Bennett’s Law, after Merrill Bennett, the agricultural economist who formulated the idea in the early 1940s. But it wasn’t really a law, because no-one had actually studied income and food purchases under controlled conditions.

Now someone has, with the first empirical test of Bennett’s Law. For Marc Bellemare, the lead author, the research, “changes your view of how the world works”.

Let’s assume that people understand what they ought to eat to keep themselves healthy over the course of their lives and that the nutritious food to deliver good health is available in the market. More than one in three of the world’s people simply cannot afford a healthy diet. We know because the Food Prices for Nutrition team at Tufts University has developed tools that allow countries to use data that most of them are already collecting (to compile their Consumer Price Index) and from them calculate the cost of a healthy diet. The results have been alarming for some policy-makers, with encouraging results in at least one country.

Anna Herforth, who first told me about the cost of a healthy diet in 2021, was in Rome recently for a workshop on diet cost metrics with her colleagues Will Masters, who leads the Food Prices for Nutrition team, Olutayo Adeyemi, from Nigeria, and Imran Chiosa from Malawi. A chance too good to miss, despite the roar of the traffic beneath us.

The Spanish are the world’s greatest anchovy eaters. They get through about 2.69 kilograms each a year, more than a tin a week. So you might be forgiven for thinking that anchovies have always been a part of Spanish cuisine. Not so, with the exception of the good people of Malaga, who developed a thing for deep-fried fresh anchovies. The rest of Spain resolutely ignored anchovies as food, spreading them instead on their fields as fertiliser. All that started to change in the late 19th century, when Italians, expert in the ways of salting fish, fetched up on the Basque coast to buy up all the fish that nobody else wanted. Among them, Giovanni Vella, who invented the modern tin of anchovy fillets in olive oil.

It was, according to Chris Beckman, author of A Twist in the Tail: how the humble anchovy flavoured Western cuisine, a win for everyone.

Anchovies can be very divisive; some people absolutely cannot stand them. I can’t get enough of the little blighters. What’s the difference? It might be as simple as the way they’re stored.

At the Dublin Gastronomy Symposium this past summer, I was delighted to learn one crucial way to improve any tin of anchovies: keep it in the fridge until you’re ready to use it.

Marcela Garcés is a professor at Siena College in New York, and as a side hustle she and her husband Yuri Morejón run La Centralita, a culinary studio that aims, among other things, “to teach guests about anchovies as a gourmet food in context”. As a result of our conversation, I now hold anchovies in even higher regard.

If only we could get over our squeamishness, insects can save the planet, banish hunger, protect the rainforests and reduce the climate catastrophe. At least, that’s what article after article tell us as they sing the praises of feeding our food waste to insects like the larvae of the black soldier fly. Insects can grow 5000-fold in 12 days, producing prodigious quantities of protein in less than 100th the space of soya beans.

There’s just one fly in the ointment, so to speak. Most of the food that insects are fed isn’t waste at all, and after absorbing large amounts of investor cash, some of the biggest companies have gone bust. Dustin Crummett, executive director of the Insect Institute, shared his many reasons for saying that eating insects will not save the planet.

Xylella fastidiosa is a bacterium that attacks all manner of plants. It prevents water getting to the leaves, so the plant essentially dies of drought. It probably arrived in Italy in 2008 but wasn’t really noticed until 2013, attacking a few trees around the town of Gallipoli in the Salento, the heel of the boot of Italy. Thanks to badly botched responses it spread, carried by spittlebug insects that live in the plants under the olives. By 2019, efforts to control the spread of Xylella were more or less abandoned, and the disease had killed 10 million olive trees in the Salento.

People – including me – thought it might be the death of olive oil production in the Salento and the rest of Puglia. In the past couple of years, however, literal green shoots of resistant olive varieties have taken hold, and with them the opportunity for a new industry focused on high-quality, profitable olive oil. To learn more, I went to visit Silvestro Silvestori, who runs The Awaiting Table cookery school in Lecce.

Some universal truths did emerge from our conversation. Fruit and veg is almost always better for the planet than meat, and homegrown is generally preferable to imported. Exceptions, however, are not uncommon, and in the end questions outnumber simple answers.
