Casting off and casting forward: an eco-friendly Tashlich on the Rio Grande

Under a wide desert sky in Albuquerque, dozens of families gathered along the bosque that hugs the Rio Grande as the afternoon light turned the water to pewter. Children clutched small mesh bags filled with rounds of dough that looked more like birdseed balls than the torn-up heels of yesterday's challah. A rabbi's voice carried across the cottonwoods, calling out the words of Tashlich, the ancient Rosh Hashanah ritual in which Jews cast breadcrumbs into a flowing stream as a way of shaking loose the mistakes of the year gone by. This time, those breadcrumbs had been replaced by compostable bread balls, baked specifically to feed the river without feeding a problem.

The shift from stale loaf to biodegradable spheres is a small but telling sign of how Jewish communities are rethinking long-held customs in light of the climate realities unfolding around them. For readers watching from across the Pacific, the scene in New Mexico offers a useful prompt: if a desert congregation can rework one of its most symbolic practices for the sake of the watershed beneath its feet, what might similar groups gathered around Sydney Harbour or the Yarra find possible?

The ancient ritual behind the breadcrumbs

Tashlich takes its name from the Hebrew word for "you will cast," drawn from the closing verses of the Book of Micah, where the prophet urges the people to cast their sins into the depths of the sea. The custom became codified in Jewish practice by the late medieval period, and most communities perform it on the first day of Rosh Hashanah, or the second if the first falls on Shabbat. The act is meant to be both communal and personal: a physical gesture paired with private reflection, a reminder that growth begins with letting go.

Bread became the medium of choice partly because it is the staff of life in Jewish tradition, the substance of blessings, the centrepiece of every Shabbat table. To toss it into a river is to acknowledge both the abundance we have been given and our tendency to mishandle it. The bread does the symbolic heavy lifting so the soul can travel light.

Why bread balls became a point of concern

For generations, the practical matter of what kind of bread to use barely registered. A few slices of white loaf, ripped into irregular chunks, drifted downstream and largely disappeared. But as rivers across the world face mounting stress from pollution, drought, and invasive species, communities have started asking sharper questions about what they are feeding their waterways. Mass-produced bread, with its preservatives and salt, can harm aquatic life and add to nutrient overloads. In some urban streams, the seasonal flotilla of Tashlich bread has even drawn grumbles from environmental officers.

The New Mexico organisers decided to do something about it. Working with a local baker who specialises in heritage grains, they developed a tightly formed ball of simple dough — flour, water, a pinch of salt — designed to dissolve quickly in moving water without leaving residue. Each participant received one ball rather than a fistful of crumbs, which both reduced waste and made the casting itself feel more deliberate.

The Rio Grande as gathering place

The Rio Grande is more than a backdrop for this ceremony. It is one of the great rivers of the American Southwest, stretching from the Colorado Rockies to the Gulf of Mexico, and it has been a gathering place for Indigenous peoples for thousands of years. Jewish settlers in New Mexico arrived in waves from the late nineteenth century onward, building synagogues and Hebrew schools in towns from Santa Fe to Las Cruces. The decision to mark the Jewish New Year on its banks ties a relatively young community to a much older sense of place.

On the day of the ceremony, families spread blankets among the cottonwoods. Teens helped younger siblings cup the bread balls in their palms. Someone had brought a guitar, and the soft strumming drifted over the water between prayers. A few passersby on the bike path paused to watch, curious about the circle forming by the river's edge.

How the eco-friendly ceremony unfolded

The structure of the service remained recognisably traditional. Participants recited the thirteen attributes of mercy, paused for personal reflection, and then approached the water's edge to cast. The difference was in the details. Instead of a crowded shoreline littered with breadcrumbs, the banks stayed clean. Each bread ball sank cleanly, and the current took it within minutes. A volunteer with a mesh net lingered at the back of the gathering, ready to retrieve any debris that did drift back.

After the casting, the group shared apples dipped in honey, a Rosh Hashanah tradition meant to usher in a sweet new year. Children ran along the trail while adults lingered, chatting about school pickups and summer plans. The atmosphere felt less like a solemn ritual and more like a community fair that happened to include prayer, which is precisely the tone many congregations are chasing these days.

Reflections from participants

Several attendees said the bread ball format made the moment feel more meaningful, not less. One mother of three told a reporter she had spent years worrying about the trail of breadcrumbs her family left behind at their local creek, and that having a cleaner option removed a small but persistent guilt. A teenager admitted he had almost skipped the ceremony that year, but the idea of doing something good for the river got him off the couch. A grandfather, who had been attending Tashlich services for six decades, simply shrugged and said the symbolism worked just as well with a ball as with a crumb.

There was also a quiet acknowledgement that Rosh Hashanah itself is about new beginnings, and that reshaping an old habit to fit a new ethic felt true to the spirit of the holiday. The new year, after all, is supposed to look different from the one before.

A parallel across the Pacific for Australian Jews

Australian Jewish communities have been weighing similar questions for years, especially in Sydney and Melbourne, where the population is concentrated around harbours, bays, and winding rivers. Congregations in the Eastern Suburbs have made Tamarama Beach a Tashlich site for decades, while Melbourne groups gather along the Yarra or at the Japanese lake in nearby Caulfield. The conversation about bread and breadcrumbs has surfaced there too, often over a quick cuppa at the kiddush following Yom Kippur.

For families thinking about how to mark the chag this year, the New Mexico example is a fair dinkum reminder that small choices can carry real weight. Replacing mass-produced loaves with homemade rolls, using less bread per person, or switching to bird-friendly seed balls are all within reach for a shule with a bit of planning. The Aussie tendency to make do with whatever is on hand, the same ingenuity that turns a Bunnings snag into a community event, translates neatly into this kind of thoughtful adaptation.

Stewardship as a continuing practice

A single afternoon by the river is a small thing in the long ledger of environmental work. What makes the New Mexico ceremony worth noting is the way it links a moment of personal reckoning to a wider ethic of care. Rosh Hashanah teaches that the world is judged as a whole, and the Talmud adds that whoever destroys a life is as if they had destroyed the entire world. Casting a biodegradable ball into a living river is a small gesture in the direction of that teaching.

For congregations looking to follow suit, the practical steps are refreshingly straightforward: partner with a local baker, source plain dough, keep portions small, and brief participants on what should and should not go in the water. The organisers in Albuquerque have begun sharing their recipe and playbook through life and culture features online, so other groups can adapt the idea without starting from scratch.

The bread ball dissolves, the prayer is said, and the year begins again. What stays with a community is not the dough itself but the shared willingness to mark the new year in a way that respects both the tradition and the watershed beneath it. That, perhaps, is the most honest kind of starting over.
