You've just sat down at a tasca in Lisbon. The waiter brings your bacalhau à brás, and with the first bite, your taste buds are hit with an intense wave of salt. This isn't a kitchen accident – it's exactly how it's meant to be. In fact, if you think Portuguese food seems saltier than other European cuisines, you're absolutely right. Official health statistics confirm what your palate is telling you.

Here's a sobering fact that might make you reach for a glass of water: Portuguese adults consume an average of 10.7 grams of salt per day, according to European health studies. That's more than double the World Health Organization's recommended maximum of 5 grams. To put this in perspective, a 2019 study in the journal Nature found that Portugal's salt intake exceeded that of Spain, Italy, and France – countries not exactly known for bland food.

The situation is so significant that Portugal became one of the first European countries to legally mandate maximum salt levels in bread back in 2009. Why bread? Because the Portuguese eat it with practically every meal, and it was identified as a major hidden source of their excessive salt consumption.

 

 

At the heart of Portugal's salty soul lies bacalhau – dried, salted cod that has somehow become the national dish of a country where cod doesn't even swim in local waters. This culinary paradox begins in the 15th century, when Portuguese sailors ventured into the frigid North Atlantic and discovered endless schools of cod off Newfoundland.

Here's where necessity became tradition: these explorers needed food that could survive months at sea without refrigeration. Their solution? Pack the fish in so much salt that bacteria couldn't possibly survive. When Portuguese sailors reached Newfoundland, in today's Canada, they came across a bigger species with bountiful white flesh, which they proceed to salt so that they'd have food for their ongoing voyages, but also to bring back home.

The process was brutally effective. The cod was so thoroughly preserved that it could last for years. Even today, despite refrigeration making such extreme preservation unnecessary, salting bacalhau has little to do with preservation and it is more about flavour development. The Portuguese have developed such a taste for it that fresh cod seems bland by comparison.

Portugal's geography made it the perfect salt producer. With endless sunshine, coastal winds, and shallow tidal areas ideal for evaporation ponds, the country became Europe's salt powerhouse. By 1178, the Rio de Aveiro became particularly important by creating enough salt for both the whole country and for exporting.

This abundance created a feedback loop: Portugal had salt, so they used salt – liberally. Portuguese salt was considered a quality product in various parts of the world. When you have a valuable commodity literally crystallizing in your backyard, you tend to find uses for it.

Walk into any Portuguese mercearia (grocery store) and you'll understand that bacalhau was just the beginning. The meat section resembles a museum of salt-cured products: chouriço, presunto, morcela, farinheira – each one saltier than the last. Before this, meat was preserved using salt, spices, dry air, smoke… and prayer. Y

These aren't just ingredients; they're the building blocks of Portuguese cuisine. That innocent-looking caldo verde? It gets its punch from a slice of salty chouriço. The hearty feijoada? Built on a foundation of various salt-cured meats. Even the simple bifana (pork sandwich) relies on meat that's been marinated in – you guessed it – a salt-heavy mixture.

Here's what many people don't realize: Portugal's salt obsession made perfect economic sense. Before the invention of salt mining, Portugal's sea salt production helped to solidify its place as a world power. Salt wasn't just a seasoning – it was currency, preservation method, and export commodity rolled into one.

Roman soldiers were often paid in salt, which is believed to be the origin of the word "salary." In Portugal, entire communities developed around salt production. The famous marnotos (salt workers) of Aveiro and the Algarve didn't just harvest salt; they created a culture around it.

Here's something Portuguese grandmothers won't tell you: after centuries of heavy salt use, Portuguese palates have adapted to require more salt to taste "normal." What seems oversalted to a French or Italian diner might seem perfectly seasoned to someone from Porto.

This adaptation shows up in unexpected places. Portuguese restaurants routinely place salt shakers on tables serving already salt-heavy dishes. Watch locals dining, and you'll often see them adding extra salt to their bacalhau – a dish that's already been soaked for 24-48 hours just to remove enough salt to make it edible.

Ironically, as health authorities battle to reduce salt consumption, Portugal's artisanal salt industry is experiencing a gourmet renaissance. Flor de sal (flower of salt) from the Algarve now commands premium prices in fancy food stores worldwide. Flor de sal is harvested in Portugal, mostly in the Aveiro District and in the Algarve using methods unchanged for centuries.

This creates a peculiar contradiction: Portugal simultaneously has a salt consumption health crisis and a booming artisanal salt export industry. It's like being the world's premier wine region while having the highest alcoholism rates – except that's kind of true too.

Understanding Portugal's salt story changes how you approach the cuisine. That overwhelming saltiness isn't a mistake or poor cooking – it's the echo of centuries of maritime history, economic necessity, and cultural evolution. When you taste that salty bacalhau, you're literally tasting history.

But here's a practical tip from someone who's made this mistake: when ordering Portuguese food, especially traditional dishes, go easy on the couvert (those "free" appetizers that aren't actually free). If you fill up on salty bread, olives, and cheese before your salty main course arrives, you'll need a swimming pool's worth of water to get through dinner.

For centuries, salt detained a preponderant role in worldwide economy and had a great influence on the culture of those connected with it. In Portugal's case, that influence went bone-deep. The saltiness of Portuguese food isn't a bug – it's a feature, programmed by centuries of survival, prosperity, and taste.

Yes, Portugal consumes too much salt by modern health standards. Yes, it can be overwhelming for visitors. But it's also an authentic expression of a culture shaped by the sea, preserved through salt, and unwilling to dilute its identity for anyone's palate. When you understand the why behind the salt, that overwhelming first bite of bacalhau transforms from a shock to a story – one that stretches from Roman salt pans to Viking traders to lonely sailors on the North Atlantic, all crystallized in a single, salty, spectacular bite.
