Amaretti di Mombaruzzo

A late-18th-century tradition attributed to Francesco Moriondo, a steward of the House of Savoy said to have brought a recipe learned from a Sicilian pastry cook back to his home village of Mombaruzzo (Asti). The Moriondo family has produced the biscuits continuously since; the product is listed in Italy's Traditional Agri-food Product (PAT) registry for Basso Monferrato.

A slight crisp skin yields to a dense, moist interior — almost fudge-like — perfumed with bitter almond and followed by long sweet-floral warmth; far more yielding than the hard Saronno type.

Armelline (apricot kernels) retain benzaldehyde volatiles after baking — responsible for the characteristic bitter-almond perfume — while amygdalin enzymes are denatured by heat, eliminating toxicity. Sweet almonds supply oleic acid: fat molecules coat protein particles during grinding, acting as a built-in tenderizer. Egg-white proteins denature and coagulate at 160°C, trapping nut oils into a firm exterior skin. Without flour, the crumb lacks gluten scaffolding; retained nut oil keeps the interior dense and moist, necessitating individual paper wrapping to prevent post-cooling surface hardening.
