Ostie Piene

Agnone, the old craft town of the Alto Molise famous for its bell foundry and coppersmiths, has a confectionery tradition of its own, and the ostie piene are among its best-known sweets, made for Christmas and feast days. The wafer itself — the ostia — is the same thin baked communion wafer cooked between hot irons, and the filling of honey, almonds and walnuts is the kind of nut-and-honey confection long made across central and southern Italy, where wafers were a common way to carry a sticky praline. Filled-wafer sweets of this type are documented in the south, the best known being the ostie ripiene of Monte Sant'Angelo in Puglia; the Agnone version belongs to the same family but is a distinct local specialty, its precise origins a matter of town tradition rather than firm record.

Crisp, brittle and intensely sweet. The thin wafers crack at the first bite to reveal a glassy, sticky layer of honey-bound nuts — toasted almonds and walnuts with their warm, oily, slightly bitter depth set against the floral sweetness of caramelised honey, often lifted with cinnamon and a little citrus zest. The texture is the pleasure: the dry snap of the ostia, the brittle shatter of the set praline, the crunch of the nuts. It is rich and best in small pieces with coffee or a sweet wine; freshly made it is crisp, but in damp air the wafers soften and lose their snap, so it is kept dry.

The filling is a honey praline: honey is heated with sugar until it reaches a high caramel stage, where most of the water has boiled off and the sugars brown and develop flavour, then toasted nuts are folded in and the mass is spread while still hot and fluid. As it cools, the concentrated sugar sets to a hard, brittle, glassy sheet that snaps cleanly — the same setting as in torrone or croccante — while toasting the almonds and walnuts first drives off moisture and develops their flavour through Maillard browning. The wafers, baked thin and dry between irons, are crisp and hygroscopic; they cap the sticky filling, are pressed so it spreads in an even layer, and keep the praline manageable to hold and cut — but because both wafer and caramel draw moisture from the air, the finished sweet must be kept dry to stay crisp.
