Coming to the Alentejo (or indeed the Extremadura) region in late spring, you’ll be greeted by a sea of yellow flowers. The plants responsible for this spectacular view are yellow lupins, or Lupinus luteus. Lupins are great nitrogen fixers and improve soil texture and drainage because of their deep roots. And while they play an important role in creating fertile soil, they are also prized for their seeds, the quintessential Portuguese snack: tremoços. Made popular by the Romans, the lupin beans have to be soaked in brine for a few days before they become edible. Once prepared, the “tremoços” are a high protein and fibre snack, with lots of antioxidant power packed in wile being relatively low in fat. You can ask for them at virtually any bar in Portugal, and they are great together with a cold beer on a warm spring evening.
