The short version
Big, flat, golden beans sold in brine, like olives. They're firm, salty and mild, and the fun is popping each bean out of its skin with your teeth. They're cheap, high in protein and almost nobody puts them on a board, which makes them a great surprise in the briny corner.
What it is
Lupini (or tremoços in Portugal) are the seeds of the white lupin plant. Raw, they're very bitter and inedible. They're soaked and boiled, then rinsed in changes of water for days to leach out the bitter alkaloids, then stored in salted brine. They're a classic Italian bar snack and a Portuguese beer partner.
- Taste
- salty, mild and nutty, a little like a firm chickpea
- Texture
- firm and snappy, with a chewy skin
- Look
- flat, round, bright golden-yellow beans
Leaching is the mechanism. The bitter compounds in lupin are water-soluble, so days of soaking and rinsing wash them out and leave a mild, protein-rich bean. Brining then seasons it and keeps it. The skin stays intact, which is why lupini keep their snap in a bowl for hours.

How to prep it for the board
- Drain and rinse them. The jar brine is very salty.
- Soak for 10 minutes in fresh water if they still taste too salty.
- Toss with olive oil, lemon zest and chili flakes for an easy upgrade.
- Serve about 1 oz per person.
- Put them in a bowl with a second small bowl for skins, and show guests how to pop them.
- Fix: if they've gone soft in the fridge, a 30-minute soak in cold salted water firms them back up.
