We’re in Os Papagaios, the restaurant Joaquim Saragga oversees in Lisbon’s Arroios neighborhood, where we’ve asked him to show us how to make one of Lisbon’s more iconic dishes: ervilhas guisadas, peas braised with Portuguese sausages, typically crowned with poached eggs. Come spring, Portugal revels in green-hued produce: fava beans, asparagus, artichoke, spinach and other leaves. Peas feature in this bounty, but the ubiquity of frozen peas means that the dish makes frequent appearances on tasca and restaurant menus during all times of year.

Start with stale, leftover bread. Add to this some of Portugal’s most decadent, richest ingredients, and you have açorda de gambas, a dish that manages to bridge the gap between poverty and indulgence. The Portuguese are masters at transforming leftover or stale bread into new dishes. In the north, leftover slices of bread are dipped in eggs, fried in oil and sprinkled with sugar in the dessert known as rabanadas. In the south, açorda is a soup made from slices of day-old bread topped with hot water, garlic, herbs, and a poached egg. The south is also home to migas, bits of stale bread and fat that are cooked into an almost omelet-like form.

“This is the best time for bivalves,” says Portuguese chef João Rodrigues. It’s late February, and we’re speaking in the dining room of Canalha, his award-winning Lisbon restaurant. “Usually you think of bivalves as something you eat in summer, but you shouldn’t. During the months with no letter R, you shouldn't eat them.” We had asked the chef to share a seasonal dish, but since proper spring produce hadn’t yet quite arrived, he suggested razor clam rice served with deep-fried hake – a fish related to cod, although with a more delicate flavor – creating a dish that takes advantage of those plump, non-summer bivalves.
