Opito Bay Salt: from the Coromandel to the world

by | Nov 16, 2023 | At Home Featured, Opinion

Salt has been a vital part of human civilization throughout history, valued as a means of preserving food and enhancing flavour. Like wine it has long been associated with a sense of place. Solnitsata, the oldest known town in Europe, was built around a salt producing facility. The port of Liverpool grew from a sleepy village into a global powerhouse because of its proximity to the Cheshire salt mines. The Polish Empire rose and fell with the fortunes of the rock salt on which its wealth depended.

Today, salt is plentiful and cheap. It is a mass-produced product, usually iodized to prevent caking (thus Cerebos salt’s famous ‘see how it runs.’ slogan, reflecting the ease with which it could be poured). But not all salts are created equal, and the best salt today is capable of enhancing and elevating food with a near-magical alchemy. The best salt also speaks of the place from which it was harvested and the people who carefully extract it from the ocean or the earth.

Opito Bay is a special place. It lies 40kms from Whitianga on the east coast of the Coromandel Peninsula and 15km from the nearest shop. According to Sustainable Coastlines, Opito Bay is one of the three cleanest beaches in New Zealand. Perry Cornish, co-founder of the Opito Bay Salt Company, refers to it as his “happy hunting ground”.

Perry and his business partner Erin Mone hatched the idea of starting a salt making venture in Perry’s Grey Lynn kitchen while enthusing over an artisan salt that Erin had procured. Perry was already cooking with Himalayan salt at home, but he saw this artisanal sea salt as a step beyond that in terms of flavour and texture.

The Opito Bay Salt Company was born.

Erin, an Irish ex-pat, was working in corporate finance at the time having spent years operating a cinema chain in Ireland. Perry came from a marketing and advertising background and had lived in Europe for many years. At the time he was also working in finance in Auckland. His father was John Cornish, the well-known chef and charcutier, so Perry always had brine in the blood.

After several months experimenting with salt-making out the back of Perry’s bach at Opito Bay, the pair packed in their corporate jobs and moved to the Coromandel fulltime. At which time the country went into its very first Covid lockdown.

During lockdown Erin and Perry continued to experiment with making salt and built their first full-sized greenhouse to aid with the evaporation of seawater. Using the sun to gently evaporate seawater (as opposed to boiling) was not only kind to the environment but also retained the trace minerals that are so integral to the salt’s flavour and health benefits.

The pair discovered that their salt was made up of 6% trace minerals compared with only 1% in most sea salts. That meant less sodium (bad) and more flavour and health-giving minerals (good). This purity and mineral wealth sets Opito Bay Salt apart, not only from bog-standard table salt, but also the majority of artisan salt makers around the world.

With the importance of the ocean and the beach to the business, Perry sees it as vital to look after their environment as much as possible. With the sun doing most of the work, the business is mostly carbon neutral. Their pumps are electric to minimise fuel usage. They have worked hard to make sure their packaging is as sustainable as possible and have installed permeable weed matting on the floors of their greenhouses so that the main by-product of the salt-making process, pure water, is returned to the earth.

Perry and Erin are enthusiastic about blending their sea salt with the finest ingredients New Zealand (and ideally Coromandel) has to offer. Their range has featured black garlic, smoked chilli, black truffle, rosemary, dry gin (for all your venison needs), as well as seasoning blends like furikake (with Coromandel kelp) and a delicious sazon. Wherever possible they will use local products and even, in the case of the rosemary salt, grow the produce themselves, with the help of a homemade seaweed fertilizer from the same beach they draw their seawater.

Artisan salt is still a fairly new concept to many New Zealanders, and it can be a challenge to convince people that it is worth the extra money to go beyond the see-how-it-runs blandness of iodized table salt. That’s why you can find Erin and Perry at farmer’s markets around the upper North Island most weekends.

For Perry, getting people to try the product is the best marketing available.

“It’s a different experience to whatever salt you may have had before,” he says. It’s not just the flavour of the salt but also the texture. When seasoning a steak, for example, a finer marine salt will quickly be absorbed into the meat. But “different sized particles give you a crunch,” says Perry, “a flavour explosion”.

Numerous gold medals from the Outstanding New Zealand Food Producer Awards and Artisan Food Awards confirm what Perry and Erin already know: that Opito Bay Salt is a special product that will enhance the cooking of any home chef. The challenge now is to get their salt into New Zealand kitchens and eventually, to the kitchens of the world.
