You might wonder how Nannini creates that delicate crunch, fragrant crumble and subtle sweetness. The secret? A blend of sweet and bitter almonds is harvested from Italy's sun-kissed groves and blended into dough. This is then hand rolled and gently baked until fine cracks appear and, while still oven-warm, dusted with icing sugar. It’s all there in the Nannini family recipe that’s barely changed since the 14th century.
