If you’ve ever visited a traditional Portuguese tasca in Portugal, you’ve likely encountered a bowl of yellow, slightly salty legumes. This is a Portuguese Snack called Tremoços. Often served alongside a cold beer, are a staple of Portuguese culture and cuisine. But what exactly are tremoços? How are they eaten, and what is their journey to becoming a beloved snack in Portugal? Let me tell you all about them in this post!
What are Tremoços?
Tremoços, known in English as lupin beans, are the seeds of the Lupinus albus plant. Once found growing wild in Portugal, tremoços have a long history and a special place in Portuguese culture and cuisine. Today, they are cultivated both for agricultural use and human consumption, remaining a staple in breweries and homes across the country. A distinctive feature of these legume beans is their bright yellow colour and unique flavour, which is both slightly nutty and subtly bitter. They are typically preserved in a brine solution, giving them a satisfying, salty taste that makes them incredibly moreish.

How are Tremoços Eaten?
Eating tremoços is an art in itself. Traditionally, they are enjoyed as a petisco (a Portuguese term for a small snack) in bars and restaurants throughout Portugal. Here’s a step-by-step guide on how to savour these tasty beans:
- Pinch and Squeeze: Hold a tremoço between your thumb and forefinger.
- Pop and Peel: Gently bite into the rind to rupture it then squeeze until the bean pops out of its skin and into your mouth.
- Enjoy: Discard the skin and relish the slightly crunchy texture and salty flavour of the bean.
They are often served chilled, making them a refreshing accompaniment to a warm day’s drink. You might also find them in salads or as part of a larger tapas spread.

The Journey to Portugal
The history of tremoços in Portugal dates back centuries. Historically, they grew spontaneously in the Portuguese landscape. Over time, farmers began to farm them intentionally, valuing them for their agricultural benefits and nutritional value. In fields, tremoços are often planted to be ploughed back into the soil or ensiled, serving as nutritious fodder for livestock. This practice not only feeds animals but also improves soil fertility, highlighting the versatility and multiple benefits of the lupin plant.
Over time their popularity as a human snack soon took off. In Portugal, we’ve perfected the art of preparing tremoços by soaking and boiling them this is to remove their natural bitterness, followed by preserving them in brine. This method makes them both delicious and safe to eat, cementing their place in Portuguese culinary traditions.
Are Tremoços Popular in Other Countries?
While tremoços are quintessentially Portuguese, they have found fans beyond Portugal’s borders. In Spain, they are known as altramuces and are similarly enjoyed as a bar snack. In Italy, lupin beans are called lupini and are popular in southern regions, often served during festive occasions. They are also consumed in various Mediterranean and Middle Eastern countries, where they are appreciated for their nutritional benefits, including high protein and fibre content.
However, it is in Portugal that tremoços have truly become an integral part of social and culinary life. Their presence in the country’s food culture is a testament to the Portuguese ability to transform simple ingredients into something delicious and memorable.

Despite their agricultural uses, the tradition of enjoying tremoços with beer is so ingrained that in Portugal, they are affectionately referred to as the “poor man’s seafood.”
Conclusion
Tremoços are more than just a snack; they are a piece of Portuguese heritage, connecting the present to the rich agricultural practices of the past. Whether you’re enjoying them in a bustling bar or incorporating them at home, these lupin beans offer a taste of Portugal’s enduring love for simple, yet delicious, foods.
