Alongside chef and restaurateur André Magalhães in his Lisbon restaurant Taberna da Rua das Flores, we stare down a rustic clay vessel piled with a mixture of steaming clams, fragrant cilantro and garlic, wedges of lemon…and not a whole lot more. As recommended by André (“It’s tastier if you use your hands”), we pinch the clams with our fingers and, after eating the meat, use the shells to scoop up the mixture of olive oil, clam broth, herbs and lemon juice that coats the bottom of the dish. It’s savory, rich, salty, tart and fragrant, and as with many Portuguese dishes, we’re left wondering how it’s possible that so much flavor came from so few ingredients.
