Sbrisolona Mantovana al Mais
Mantua, Lombardy
Mantua's crumble cake — a coarse-textured shortbread made from a mixture of coarse maize flour (farina gialla grossa), plain flour, butter, lard, sugar, toasted almonds, eggs, vanilla, and lemon zest. Unlike standard shortbread which is pressed and cut, sbrisolona ('sbrisolare' = to crumble) is deliberately crumbled — the dough is made by rubbing fat into flour until it resembles coarse crumbs, then this mixture is pressed loosely into the pan without cohesion. It bakes into a rough, fragile sheet that must be broken by hand at the table — cutting with a knife is wrong.
